Cyber Crime
Cyber Pornography
Cyber pornography is believed to be one of the largest businesses on the
Internet today. The millions of pornographic websites that flourish on the
Internet are testimony to this. While pornography per se is not illegal in
many countries, child pornography is strictly illegal in most nations today.
Cyber pornography covers pornographic websites, pornographic
magazines produced using computers (to publish and print the material)
and the Internet (to download and transmit pornographic pictures,
photos, writings etc).
Illustration 1
A school student from Delhi (India),
who was regularly teased for having
a pockmarked face, used a free
hosting provider to create
www.amazing-gents.8m.net.
He regularly uploaded “morphed”
photographs of teachers and girls
from his school onto the website.
He was arrested when the father of
one of the victims reported the case
to the police.
Illustration 2
The CEO of online auction website
bazee.com (a part of the ebay
group) was arrested by the Delhi
police for violating India’s strict laws
on cyber pornography. An
engineering student was using the
bazee website to sell a video
depicting two school students
having sexual intercourse.
Bazee.com was held liable for
distributing porn and hence the
CEO was arrested.
Illustration 3
The CEO of a software company in
Pune (India) was arrested for
sending highly obscene emails to a
former employee.
Sale of Illegal Articles
It is becoming increasingly common to find cases where sale of illegal
articles such as narcotics drugs, weapons, wildlife etc. is being facilitated
by the Internet. Information about the availability of the products for sale
is being posted on auction websites, bulletin boards etc.
It is practically impossible to control
or prevent a criminal from setting up
a website to transact in illegal
articles. Additionally, there are
several online payment gateways
that can transfer money around the
world at the click of a button.
The Internet has also created a marketplace for the sale of unapproved
drugs, prescription drugs dispensed without a valid prescription, or
products marketed with fraudulent health claims.
Many sites focus on selling
prescription drugs and are referred
to by some as “Internet
pharmacies.” These sites offer for
sale either approved prescription
drug products, or in some cases,
unapproved, illegal versions of
prescription drugs. This poses a
serious potential threat to the health
and safety of patients.
The broad reach, relative
anonymity, and ease of creating
new or removing old websites,
poses great challenges for law
enforcement officials.
Illustration
In March 2007, the Pune rural
police cracked down on an illegal
rave party and arrested hundreds of
illegal drug users. The social
networking site Orkut.com is
believed to be one of the modes of
communication for gathering people
for the illegal “drug” party.
Online Gambling
There are thousands of websites that offer online gambling. The special
issue with online gambling is that it is legalised in several countries. So
legally the owners of these websites are safe in their home countries.
The legal issues arise when a person residing in a foreign country like
India (where such websites are illegal) gambles on such a website.
Illustration
The website ladbrokes.com
permits users to gamble on a
variety of sports such as cricket,
football, tennis, golf, motor racing,
ice hockey, basketball, baseball,
darts, snooker, boxing, athletics,
rugby, volleyball, motor cycling etc.
Additionally it also features an
online casino. The website has no
technical measures in place to
prohibit residents of certain
countries (where online gambling is
illegal) from betting at their website.
Intellectual Property Crimes
These include software piracy, copyright infringement, trademarks
violations, theft of computer source code etc.
Illustration 1
A software professional from
Bangalore (India) was booked for
stealing the source code of a
product being developed by his
employers. He started his own
company and allegedly used the
stolen source code to launch a new
software product.
Illustration 2
In 2003, a computer user in China
obtained the source code of a
popular game - LineageII from an
unprotected website. This
proprietary code was then sold to
several people in 2004. One of
those people set up a website,
www.l2extreme.com, to offer the
“Lineage” game at a discount.
Despite legal warnings from the
South Korean company that owned
the Lineage source code, the
suspect did not shut down the site.
He rented powerful servers -
enough to accommodate 4,000
simultaneous gamers - and solicited
donations from users to help defray
the costs.
The loss in potential revenues for
the South Korean company was
estimated at $750,000 a month. The
US FBI arrested the suspect and
the website was shut down.
Email Spoofing
A spoofed email is one that appears to originate from one source but
actually has been sent from another source e.g Pooja has an e-mail
address pooja@asianlaws.org.
Her ex-boyfriend, Sameer spoofs her e-mail and sends obscene
messages to all her acquaintances. Since the e-mails appear to have
originated from Pooja, her friends may take offence and relationships
may be spoiled for life.
Illustration 1
In an American case, a teenager
made millions of dollars by
spreading false information about
certain companies whose shares he
had short sold.
This misinformation was spread by
sending spoofed emails, purportedly
from news agencies like Reuters, to
share brokers and investors who
were informed that the companies
were doing very badly.
Even after the truth came out the
values of the shares did not go back
to the earlier levels and thousands
of investors lost a lot of money.
Illustration 2
A branch of the erstwhile Global
Trust Bank in India experienced a
run on the bank. Numerous
customers decided to withdraw all
their money and close their
accounts.
An investigation revealed that
someone had sent out spoofed
emails to many of the bank’s
customers stating that the bank was
in very bad shape financially and
could close operations at any time.
The spoofed email appeared to
have originated from the bank itself.
Forgery
Counterfeit currency notes, postage and revenue stamps, mark sheets,
academic certificates etc are made by criminals using sophisticated
computers, printers and scanners.
Illustration 1
In October 1995, Economic
Offences Wing of Crime Branch,
Mumbai (India), seized over 22,000
counterfeit share certificates of eight
reputed companies worth Rs. 34.47
crores. These were allegedly
prepared using Desk Top
Publishing Systems.
Illustration 2
Abdul Kareem Telgi, along with
several others, was convicted in
India on several counts of
counterfeiting stamp papers and
postage stamps totalling several
billion rupees.
Cyber Defamation
This occurs when defamation takes place with the help of computers and
/ or the Internet. e.g. Sameer publishes defamatory matter about Pooja
on a website or sends e-mails containing defamatory information to
Pooja’s friends.
Illustration 1
Abhishek, a teenaged student was
arrested by the Thane police in
India following a girl’s complaint
about tarnishing her image in the
social networking site Orkut.
Abhishek had allegedly created a
fake account in the name of the girl
with her mobile number posted on
the profile.
The profile had been sketched in
such a way that it drew lewd
comments from many who visited
her profile. The Thane Cyber Cell
tracked down Abhishek from the
false e-mail id that he had created
to open up the account.
Illustration 2
The Aurangabad bench of the
Bombay high court issued a notice
to Google.com following a public
interest litigation initiated by a
young lawyer.
The lawyer took exception to a
community called ‘We hate India’,
owned by someone who identified
himself as Miroslav Stankovic. The
community featured a picture of the
Indian flag being burnt.
Illustration 3
Unidentified persons posted
obscene photographs and contact
details of a Delhi school girl.
Suggestive names like ’sex teacher’
were posted on the profile.
The matter came to light after the
girl’s family started receiving vulgar
calls referring to Orkut.
Cyber Stalking
Cyber stalking refers to the use of the Internet, e-mail, or other electronic
communications devices to stalk another person.
Stalking generally involves harassing or threatening behaviour that an
individual engages in repeatedly, such as following a person, appearing
at a person's home or place of business, making harassing phone calls,
leaving written messages or objects, or vandalizing a person's property.
Most stalking laws require that the perpetrator make a credible threat of
violence against the victim; others include threats against the victim's
immediate family.
Illustration 1
In the first successful prosecution
under the California (USA) cyber
stalking law, prosecutors obtained a
guilty plea from a 50-year-old
former security guard who used the
Internet to solicit the rape of a
woman who rejected his romantic
advances.
He terrorized the 28-year-old victim
by impersonating her in various
Internet chat rooms and online
bulletin boards, where he posted,
along with her telephone number
and address, messages that she
fantasized about being raped.
On at least six occasions,
sometimes in the middle of the
night, men knocked on the woman's
door saying they wanted to rape
her.
Illustration 2
An honours graduate from the
University of San Diego in USA
terrorized five female university
students over the Internet for more
than a year.
The victims received hundreds of
violent and threatening e-mails,
sometimes receiving four or five
messages a day.
The student, who pleaded guilty,
told the police that he had

committed the crimes because he
thought the women were laughing
at him and causing others to ridicule
him. In reality, the victims had never
met him.
Illustration 3
In 2005, a minor from
Massachusetts (USA) was
convicted in connection with
approximately $1 million in victim
damages.
Over a 15-month period, he had
hacked into Internet and telephone
service providers, stolen an
individual’s personal information
and posted it on the Internet, and
made bomb threats to many high
schools.
Web defacement
Website defacement is usually the substitution of the original home page
of a website with another page (usually pornographic or defamatory in
nature) by a hacker.
Religious and government sites are regularly targeted by hackers in
order to display political or religious beliefs. Disturbing images and
offensive phrases might be displayed in the process, as well as a
signature of sorts, to show who was responsible for the defacement.
Websites are not only defaced for political reasons, many defacers do it
just for the thrill. For example, there are online contests in which hackers
are awarded points for defacing the largest number of web sites in a
specified amount of time. Corporations are also targeted more often than
other sites on the Internet and they often seek to take measures to
protect themselves from defacement or hacking in general.
Web sites represent the image of a company or organisation and these
are therefore especially vulnerable to defacement. Visitors may lose faith
in sites that cannot promise security and will become wary of performing
online transactions. After defacement, sites have to be shut down for
repairs, sometimes for an extended period of time, causing expenses
and loss of profit.
Illustration 1
Mahesh Mhatre and Anand Khare
(alias Dr Neukar) were arrested in
2002 for allegedly defacing the
website of the Mumbai Cyber Crime
Cell.
They had allegedly used password
cracking software to crack the FTP
password for the police website.
They then replaced the homepage
of the website with pornographic
content. The duo was also charged
with credit card fraud for using 225
credit card numbers, mostly
belonging to American citizens.
Illustration 2
In 2001, over 200 Indian websites
were hacked into and defaced. The
hackers put in words like bugz,
death symbol, Paki-king and
allahhuakbar.
In the case of 123medicinindia.com,
a message was left behind which
said – “Catch me if uuu can my
Asian School of Cyber Laws

deraz lazy adminzzz” – challenging
the system administrators to trace
the miscreants.
The offenders were allegedly a
group of hackers who go by the
name of ‘Pakistani Cyber Warriors’.
Illustration 3
In 2006, a Turkish hacker using the
handle iSKORPiTX was able to
breach the security of a group of
web servers, containing more than
38,500 web sites in less than a day!
Illustration 4
The first Defacers Challenge took
place on Sunday, July 6, 2003.
There was a special prize for the
first contestant to deface 6,000 web
sites.
The contest was conducted over a
six-hour period. Points were
awarded based on the server’s
operating system.
Windows: 1 point,
Linux: 2 points,
BSD: 2 points,
AIX: 3 points,
HP-UX: 5 points
Macintosh: 5 points
Email Bombing
Email bombing refers to sending a large number of emails to the victim
resulting in the victim’s email account (in case of an individual) or mail
servers (in case of a company or an email service provider) crashing.
Email bombing is a type of denial-of-service attack. A denial-of-service
attack is one in which a flood of information requests is sent to a server,
bringing the system to its knees and making the server difficult to access.
Illustration 1
A British teenager was cleared of
launching a denial-of-service attack
against his former employer, in a
ruling under the UK Computer
Misuse Act.
The teenager was accused of
sending 5 million e-mail messages
to his ex-employer that caused the
company's e-mail server to crash.
The judge held that the UK
Computer Misuse Act does not
specifically include a denial-ofservice attack as a criminal offence.
Illustration 2
In one case, a foreigner who had
been residing in Simla, India for
almost 30 years wanted to avail of a
scheme introduced by the Simla
Housing Board to buy land at lower
rates. When he made an application
it was rejected on the grounds that
the scheme was available only for
citizens of India.
He decided to take his revenge.
Consequently, he sent thousands of
mails to the Simla Housing Board
and repeatedly kept sending e-mails
till their servers crashed.
Data Diddling
One of the most common forms of computer crime is data diddling -
illegal or unauthorized data alteration. These changes can occur before
and during data input or before output. Data diddling cases have affected
banks, payrolls, inventory records, credit records, school transcripts and
virtually all other forms of data processing known.
Illustration 1
The NDMC Electricity Billing Fraud
Case that took place in 1996 is a
typical example. The computer
network was used for receipt and
accounting of electricity bills by the
New Delhi Municipal Council.
Collection of money, computerized
accounting, record maintenance
and remittance in the bank were
exclusively left to a private
contractor who was a computer
professional.
He misappropriated huge amount of
funds by manipulating data files to
show less receipt and bank
remittance.
Illustration 2
A keyboard operator processing
orders at an Oakland USA
department store changed some
delivery addresses and diverted
several thousand dollars worth of
store goods into the hands of
accomplices.
Illustration 3
A ticket clerk at the Arizona
Veterans' Memorial Coliseum in
USA issued full-price basketball
tickets, sold them and then, tapping
out codes on her computer
keyboard, recorded the transactions
as half-price sales.
Salami Attacks
These attacks are used for committing financial crimes. The key here is
to make the alteration so insignificant that in a single case it would go
completely unnoticed.
For instance, a bank employee inserts a program, into the bank’s
servers, that deducts a small amount of money (say Rs. 2 a month) from
the account of every customer. No account holder will probably notice
this unauthorized debit, but the bank employee will make a sizeable
amount of money every month.
The attack is called “salami attack” as it is analogous to slicing the data
thinly, like a salami.
Illustration 1
Four executives of a rental-car
franchise in Florida USA defrauded
at least 47,000 customers using a
salami technique.
They modified a computer billing
program to add five extra gallons to
the actual gas tank capacity of their
vehicles.
From 1988 through 1991, every
customer who returned a car
without topping it off ended up
paying inflated rates for an inflated
total of gasoline.
The thefts ranged from $2 to $15
per customer - difficult for the
victims to detect.
Illustration 2
In January 1997, Willis Robinson of
Maryland USA, was sentenced to
10 years in prison for “having
reprogrammed his Taco Bell driveup-window cash register - causing it
to ring up each $2.99 item internally
as a 1-cent item, so that he could
pocket $2.98 each time”.
The management assumed the
error was hardware or software and
only caught the perpetrator when he
bragged about his crime to coworkers.
Illustration 3
In Los Angeles USA four men were
charged with fraud for allegedly
installing computer chips in gasoline
pumps that cheated consumers by
overstating the amounts pumped.
The problem came to light when an
increasing number of consumers
claimed that they had been sold
more gasoline than the capacity of
their gas tanks!
However, the fraud was difficult to
prove initially because the
perpetrators programmed the chips
to deliver exactly the right amount of
gasoline when asked for five- and
10-gallon amounts (precisely the
amounts typically used by
inspectors).
Denial of Service Attack
Denial of Service attacks (DOS attacks) involve flooding a computer with
more requests than it can handle. This causes the computer (e.g. a web
server) to crash and results in authorized users being unable to access
the service offered by the computer.
Another variation to a typical denial of service attack is known as a
Distributed Denial of Service (DDoS) attack wherein the perpetrators are
many and are geographically widespread.
Illustration 1
A series of distributed denial of
service attacks in February 2000
crippled many popular websites
including yahoo.com, amazon.com
and cnn.com
Illustration 2
A series of more than 125 separate
but coordinated denial of service
attacks hit the cyber infrastructure
of Estonia in early 2007.
The attacks were apparently
connected with protests against the
Estonian government's decision to
remove a Soviet-era war memorial
from the capital city.
It is suspected that the attacks were
carried out by Russian hackers. The
attack lasted several days.
Virus / Worm Attacks
Computer viruses are small software programs that are designed to
spread from one computer to another and to interfere with computer
operation. A virus might corrupt or delete data on the victim’s computer,
use the victim’s e-mail program to spread itself to other computers, or
even erase everything on the victim’s hard disk.
Viruses are most easily spread by attachments in e-mail messages or
instant messaging messages. Viruses can be disguised as attachments
of funny images, greeting cards, or audio and video files. Viruses can
also spread through downloads on the Internet. They can be hidden in
illicit software or other files or programs.
Worms, unlike viruses do not need the host to attach themselves to.
They merely make functional copies of themselves and do this
repeatedly till they eat up all the available space on a computer’s
memory.
Brain (in its first incarnation written in January 1986) is considered to be
the first computer virus for the PC. The virus is also known as Lahore,
Pakistani, Pakistani Brain, Brain-A and UIUC. The virus was written by
two brothers, Basit and Amjad Farooq Alvi, who lived in Lahore,
Pakistan. The brothers told TIME magazine they had written it to protect
their medical software from piracy and was supposed to target copyright
infringers only.
The virus came complete with the brothers' address and three phone
numbers, and a message that told the user that their machine was
infected and for inoculation the user should call them.
When the brothers began to receive a large number of phone calls from
people in USA, Britain, and elsewhere, demanding them to disinfect their
machines, the brothers were stunned and tried to explain to the outraged
callers that their motivation had not been malicious.
They ended up having to get their phone lines cut off and regretted that
they had revealed their contact details in the first place. The brothers are
still in business in Pakistan as internet service providers in their company
called Brain Limited.
Illustration 1
The VBS_LOVELETTER virus
(better known as the Love Bug or
the ILOVEYOU virus) was
reportedly written by a Filipino
undergraduate. In May 2000, this
deadly virus became the world’s
most prevalent virus. Losses
incurred during this virus attack
were pegged at US $ 10 billion.
VBS_LOVELETTER utilized the
addresses in Microsoft Outlook and
e-mailed itself to those addresses.
The e-mail, which was sent out, had
“ILOVEYOU” in its subject line. The
attachment file was named “LOVELETTER-FOR-YOU.TXT.vbs”.
People wary of opening e-mail
attachments were conquered by the
subject line and those who had
some knowledge of viruses, did not
notice the tiny .vbs extension and
believed the file to be a text file. The
message in the e-mail was “kindly
check the attached LOVELETTER
coming from me”.
Illustration 2
Probably the world’s most famous
worm was the Internet worm let
loose on the Internet by Robert
Morris sometime in 1988. The
Internet was, then, still in its
developing years and this worm,
which affected thousands of
computers, almost brought its
development to a complete halt. It
took a team of experts almost three
days to get rid of the worm and in
the meantime many of the
computers had to be disconnected
from the network.

In 2002, the creator of the Melissa
computer virus was convicted. The
virus had spread in 1999 and
caused more than $80 million in
damage by disrupting personal
computers, business and
government computer networks.

In 2006, a US citizen was convicted
for conspiracy to intentionally cause

Between 2004 and 2005, he
created and operated a malicious
software to constantly scan for and
infect new computers.
It damaged hundreds of US
Department of Defence computers
in USA, Germany and Italy. The
software compromised computer
systems at a Seattle hospital,
including patient systems, and
damaged more than 1,000
computers in a California school
district.

Logic bombs are event dependent
programs. This implies that these
programs are created to do
something only when a certain
event (known as a trigger event)
occurs. e.g. even some viruses may
be termed logic bombs because
they lie dormant all through the year
and become active only on a
particular date (like the Chernobyl
virus).
Trojans and Keyloggers
A Trojan, as this program is aptly called, is an unauthorized program
which functions from inside what seems to be an authorized program,
thereby concealing what it is actually doing.
Keyloggers are regularly used were to log all the strokes a victim makes
on the keyboard. This assumes sinister proportions, if a key logger is
installed on a computer which is regularly used for online banking and
other financial transactions. Key-loggers are most commonly found in
public computers such as those in cyber cafes, hotels etc. Unsuspecting
victims also end up downloading spyware when they click on “friendly”
offers for free software.
Illustration 1
A young lady reporter was working
on an article about online
relationships. The article focused on
how people can easily find
friendship and even love on the
Internet. During the course of her
research she made a lot of online
friends. One of these ‘friends’
managed to infect her computer
with a Trojan.
This young lady stayed in a small
one bedroom apartment and her
computer was located in one corner
of her bedroom. Unknown to her,
the Trojan would activate her web
camera and microphone even when
the Internet was switched off. A
year later she realized that
hundreds of her pictures were
posted on pornographic sites
around the world!

The network administrator in a
global bank received a beautifully
packed CD ROM containing
“security updates” from the
company that developed the
operating system that ran his bank’s
servers.
He installed the “updates” which in
reality was Trojanized software. 3
years later, the effects were still
being felt in the bank’s system!
Internet Time Theft
This connotes the usage by an unauthorized person of the Internet hours
paid for by another person.
Illustration
In May 2000, the Delhi police
arrested an engineer who had
misused the login name and
password of a customer whose
Internet connection he had set up.
The case was filed under the Indian
Penal Code and the Indian
Telegraph Act.
Web Jacking
Just as conventional hijacking of an airplane is done by using force,
similarly web jacking means forcefully taking over control of a website.
The motive is usually the same as hijacking – ransom. The perpetrators
have either a monetary or political purpose which they try to satiate by
holding the owners of the website to ransom.
This occurs when someone forcefully takes control of a website (by
cracking the password and later changing it). The actual owner of the
website does not have any more control over what appears on that
website.
How does web jacking take place?
The administrator of any website
has a password and a username
that only he (or someone authorized
by him) may use to upload files from
his computer on the web server
(simply put, a server is a powerful
computer) where his website is
hosted.
Ideally, this password remains
secret with the administrator. If a
hacker gets hold of this username
and password, then he can pretend
to be the administrator.
Computers don’t recognize people –
only usernames and passwords.
The web server will grant control of
the website to whoever enters the
correct password and username
combination.
There are many ways in which a
hacker may get to know a
password, the most common being
password cracking wherein a
“cracking software” is used to guess
a password. Password cracking
attacks are most commonly of two
types.
The first one is known as the
dictionary attack. In this type of
attack the software will attempt all
the words contained in a predefined
dictionary of words.
For example, it may try Rahim,
Rahul, Rakesh, Ram, Reema,
Reena … in a predefined dictionary
of Indian names. These types of
dictionaries are readily available on
the Internet.
The other form of password
cracking is by using ‘brute force’. In
this kind of attack the software tries
to guess the password by trying out
all possible combinations of
numbers, symbols, letters till the
correct password is found. For
example, it may try out password
combinations like abc123,
acbd5679, sdj#%^, weuf*(-)*.
Some software, available for
password cracking using the brute
force technique, can check a huge
number of password combinations
per second.
When compared with a dictionary
attack, a brute force attack takes
more time, but it is definitely more
successful.
Illustration
In an incident reported in the USA,
the owner of a hobby website for
children received an e-mail
informing her that a group of
hackers had gained control over her
website. They demanded a ransom
of 1 million dollars from her.
The owner, a schoolteacher, did not
take the threat seriously. She felt
that it was just a scare tactic and
ignored the e-mail.
It was three days later that she
came to know, following many
telephone calls from all over the
country, that the hackers had web
jacked her website. Subsequently,
they had altered a portion of the
website which was entitled ‘How to
have fun with goldfish’.
In all the places where it had been
mentioned, they had replaced the
word ‘goldfish’ with the word
‘piranhas’.
Piranhas are tiny but extremely
dangerous flesh-eating fish. Many
children had visited the popular
website and had believed what the
contents of the website suggested.
These unfortunate children followed
the instructions, tried to play with
piranhas, which they bought from
pet shops, and were very seriously
injured!
Email Frauds
Dear Mr. Justin Williams, I'm Vikas Manjit Singh from
Punjab (India). I belong to a city named Ludhiana.
Mr. Williams, I am having a brother in Canada who is also
named Justin Williams. He was adopted from my parents
by some Mr. William Ram of Welland. Me and my mum
came over to Canada to leave Justin to his new family
(William Ram's Family). It happened in June 1985.
So Mr. Justin Williams, if you are the same person I'm
talking about. Then please give me some time so that I
can let you know the realities.
Imagine the thoughts going through Mr. Justin William’s head after
reading this email. Is he really adopted? Where are his birth parents? Is
this email from his birth brother?
In reality, this is a scam email originating from a college in Sangroor
(India)! Canadian citizens are targeted with these emails. If the targets
start believing the sender to be their brother, they are asked to send
money so that their “brother” can travel to Canada with the proof of the
victim’s adoption!
This is just one of the hundreds of email scams being perpetrated on the
Internet. These scams are commonly referred to as Nigerian 419 scams.
These scam emails are believed to originate from Nigeria and section
419 of the Nigerian Penal Code relates to cheating (like the famous
section 420 of the Indian Penal Code).
The 419 letter scams originated in the early 1980s as the oil-based
economy of Nigeria went downhill. In the 1990s, letter scams gave way
to email scams.
In 2007, Asian School of Cyber Laws conducted a 3 month intensive
investigation of hundreds of scam emails. The results were very
surprising to say the least. Less than 10% of these emails had actually
originated from Nigeria!
A majority of these emails (more than 60%) have originated from Israel,
followed by the Netherlands, UK and other European countries. The
“birth brother” email was the only one originating from India.
Most of these scam emails promise the receiver millions (or sometimes
billions) of dollars. Most commonly the email says that some rich African
bureaucrat or businessman or politician has died and left behind a lot of
money.
The scamster states that the Government is going to confiscate the
money. The only way out is to transfer the money to the bank account of
the email recipient. All that the email recipient has to do is send his bank
account details. For this a generous fee of a few million dollars will be
paid!
If someone actually falls for this scam and provides the bank details, he
is sent some official looking documents relating to the bank transfer of a
huge sum of money. Once the victim is convinced of the “genuineness”
of the transaction, something appears to go wrong.
The victim is informed that a small amount of money (ranging from US$
100 to 2500) is needed for bank charges or other paper work. This
money is the motive behind the elaborate scam. Once the victim pays
this money, the scamster disappears from the scene.
The lottery scam emails inform the recipient that he has won a million
dollar lottery run by Microsoft, Yahoo or some other well known global
company. The winner is asked to provide his bank details and pay a
small sum for bank charges and other processing fees.
Another scam email begins with “This is to inform you that we are in
possession of a consignment, deposited by British National Lottery which
is to be couriered to you”. The email asks for 470 pounds to be sent to
the courier company so that the cheque for the lottery prize can be sent.
Another scam email comes with the subject line “Blessed is the hand that
giveth”. The sender claims to be a widow on her deathbed. She wants to
donate her wealth to someone who will pray for her.
Another scam email comes from an “employee of the Euro Lottery”. The
“employee” claims to be in a position to carry out a lottery fraud and is
willing to share the money with the email recipient.
What is common in all these scams is that scanned versions of official
documents are emailed to potential victims. Once the victim is convinced
of the genuineness of the transaction, a small fee is requested for
meeting bank charges / legal fees / courier charges etc. It is this small
fee that is the motive behind the scam.
It is believed that thousands of people are defrauded of billions of dollars
every year through these scams.
Illustration 1
In 2005, an Indian businessman
received an email from the Vice
President of a major African bank
offering him a lucrative contract in
return for a kickback of Rs 1 million.
The businessman had many
telephonic conversations with the
sender of the email. He also verified
the email address of the ‘Vice
President’ from the website of the
bank and subsequently transferred
the money to the bank account
mentioned in the email. It later
turned out that the email was a
spoofed one and was actually sent
by an Indian based in Nigeria.
Illustration 2
A new type of scam e-mail
threatens to kill recipients if they do
not pay thousands of dollars to the
sender, who purports to be a hired
assassin.
Replying to the e-mails just sends a
signal to senders that they’ve
reached a live account. It also
escalates the intimidation.
In one case, a recipient threatened
to call authorities. The scammer,
who was demanding $20,000,
reiterated the threat and sent some
personal details about the
recipient—address, daughter’s full
name etc. He gave an ultimatum:
“TELL ME NOW ARE YOU READY
TO DO WHAT I SAID OR DO YOU
WANT ME TO PROCEED WITH
MY JOB? ANSWER YES/NO AND
DON’T ASK ANY QUESTIONS!!!”
Some emails claim to be from the
FBI in London and inform recipients
that an arrest was made in the
case.
The e-mail says the recipient’s
information was found with the
suspect and that they should reply
to assist in the investigation. These
emails are part of the scam!
Cyber Terrorism
Computer crime has hit mankind with unbelievable severity. Computer
viruses, worms, Trojans, denial of service attacks, spoofing attacks and
e-frauds have taken the real and virtual worlds by storm.
However, all these pale in the face of the most dreaded threat – that of
cyber terrorism.
Asian School of Cyber Laws has defined cyber terrorism as:
Cyber terrorism is the premeditated use of disruptive
activities, or the threat thereof, in cyber space, with the
intention to further social, ideological, religious, political or
similar objectives, or to intimidate any person in furtherance
of such objectives.
Illustration 1
In 1996, a computer hacker
allegedly associated with the White
Supremacist movement temporarily
disabled a US based Internet
Service Provider (ISP) and
damaged part of its record keeping
system.
The ISP had attempted to stop the
hacker from sending out worldwide
racist messages under the ISP's
name. The hacker signed off with
the threat, "you have yet to see true
electronic terrorism. This is a
promise."
Illustration 2
In 1998, Spanish protestors
bombarded the Institute for Global
Communications (IGC) with
thousands of bogus e-mail
messages. E-mail was tied up and
undeliverable to the ISP's users,
and support lines were tied up with
people who couldn't get their mail.
The protestors also spammed IGC
staff and member accounts,
clogged their Web page with bogus
credit card orders, and threatened
to employ the same tactics against
organizations using IGC services.
They demanded that IGC stop
hosting the website for the Euskal
Herria Journal, a New York-based
publication supporting Basque
independence.
Protestors said IGC supported
terrorism because a section on the
Web pages contained materials on
the terrorist group ETA, which
claimed responsibility for
assassinations of Spanish political
and security officials, and attacks on
military installations. IGC finally
relented and pulled the site because
of the "mail bombings."
Illustration 3
In 1998, a 12-year-old boy
successfully hacked into the
controls for the huge Roosevelt
Dam on the Salt River in Arizona,
USA.
He might have released floodwaters
that would have inundated Mesa
and Tempe, endangering at least 1
million people.
Illustration 4
In 2005, US security consultants
reported that hackers were targeting
the U.S. electric power grid and had
gained access to U.S. utilities’
electronic control systems.
Illustration 5
In 1998, ethnic Tamil guerrillas
swamped Sri Lankan embassies
with 800 e-mails a day over a twoweek period.
The messages read "We are the
Internet Black Tigers and we're
doing this to disrupt your
communications." Intelligence
authorities characterized it as the
first known attack by terrorists
against a country's computer
systems.
Illustration 6
During the Kosovo conflict in 1999,
NATO computers were blasted with
e-mail bombs and hit with denial-ofservice attacks by hacktivists
protesting the NATO bombings.
In addition, businesses, public
organizations, and academic
institutes received highly politicized
virus-laden e-mails from a range of
Eastern European countries,
according to reports. Web
defacements were also common.
Illustration 7
Since December 1997, the
Electronic Disturbance Theater
(EDT) has been conducting Web
sit-ins against various sites in
support of the Mexican Zapatistas.
At a designated time, thousands of
protestors point their browsers to a
target site using software that floods
the target with rapid and repeated
download requests.
EDT's software has also been used
by animal rights groups against
organizations said to abuse
animals.
Electrohippies, another group of
hacktivists, conducted Web sit-ins
against the WTO when they met in
Seattle in late 1999.
Illustration 8
In 1994, a 16-year-old English boy
took down some 100 U.S. defense
systems.
Illustration 9
In 1997, 35 computer specialists
used hacking tools freely available
on 1,900 web sites to shut down
large segments of the US power
grid. They also silenced the
command and control system of the
Pacific Command in Honolulu.
Illustration 10
In 2000, Asian School of Cyber
Laws was regularly attacked by
Distributed Denial of Service attacks
by “hactivists” propagating the “right
to pornography”. Asian School of
Cyber Laws has spearheaded an
international campaign against
pornography on the Internet.
Illustration 11
In 2001, in the backdrop of the
downturn in US-China relationships,
the Chinese hackers released the
Code Red virus into the wild. This
virus infected millions of computers
around the world and then used
these computers to launch denial of
service attacks on US web sites,
prominently the web site of the
White House.
Illustration 12
In 2001, hackers broke into the U.S.
Justice Department's web site and
replaced the department's seal with
a swastika, dubbed the agency the
"United States Department of
Injustice" and filled the page with
obscene pictures.
Use of encryption by terrorists
A disturbing trend that is emerging nowadays is the increasing use of
encryption, high-frequency encrypted voice/data links, encryption
software like Pretty Good Privacy (PGP) etc by terrorists and members of
organized crime cartels.
Strong encryption is the criminal’s best friend and the policeman’s worst
enemy.
Illustration 1
Leary, who was sentenced to 94
years in prison for setting off fire
bombs in the New York (USA)
subway system in 1995, had
developed his own algorithm for
encrypting the files on his computer.
Illustration 2
The Cali cartel is reputed to be
using
• sophisticated encryption to
conceal their telephone
communications,
• radios that distort voices,
• video phones which provide
visual authentication of the
caller's identity, and
• instruments for scrambling
transmissions from
computer modems.
Illustration 3
The Italian mafia is believed to use
PGP (Pretty Good Privacy) software
for symmetric as well as asymmetric
encryption.
Illustration 4
On March 20, 1995, the Aum
Supreme Truth cult dropped bags of
sarin nerve gas in the Tokyo
subway, killing 12 people and
injuring 6,000 more.
Members of the cult had developed
many chemical and biological
weapons, including Sarin, VX,
Mustard gas, Cyanide, botulism,
anthrax and Q fever.

It is believed that preparations were
underway to develop nuclear
capability. The cult was also
believed to be developing a "death
ray" that could destroy all life!
The records of the cult had been
stored in encrypted form (using the
RSA algorithm) on computers.
The enforcement authorities were
able to decrypt the information as
the relevant private key was found
in a floppy disk seized from the
cult’s premises. The encrypted
information related to plans of the
cult to cause mass deaths in Japan
and USA.
Illustration 5
In 1997, a Bolivian terrorist
organization had assassinated four
U.S. army personnel.
A raid on one of the hideouts of the
terrorists yielded information
encrypted using symmetric
encryption.
A 12-hour brute force attack
resulted in the decryption of the
information and subsequently led to
one of the largest drug busts in
Bolivian history and the arrest of the
terrorists.
Illustration 6
James Bell was arrested for
violating internal revenue laws of
the USA. He did this by:
ƒ collecting the names and
home addresses of agents
and employees of the
Internal Revenue Service
(IRS) of the USA in order to
intimidate them
ƒ soliciting people to join in a
scheme known as
"Assassination Politics".
Under this scheme those
who killed selected
government employees,
including tax collectors,
would be rewarded;
ƒ using false Social Security
Numbers to hide his assets
and avoid taxes;
ƒ contaminating an area
outside IRS premises in
many states of the USA with
Mercaptan (a stink gas).
Investigators found on his computer
documents relating to a plan to
destroy electronic equipment with
nickel-plated carbon fiber.
They also found an invoice for the
purchase of the fiber at his
residence, and a bundle of the
material at the residence of his
associate, Robert East. Bell had
exchanged PGP-encrypted e-mail
messages with some of his
associates.
As part of his plea bargain, he
turned over the passphrase to his
private key. This allowed
investigators to decrypt messages
that he had received.
Illustration 7
Dutch organized crime syndicates
use PGP and PGPfone to encrypt
their communications. They also
use palmtop computers installed
with Secure Device, a Dutch
software product for encrypting data
with International Data Encryption
Algorithm (IDEA).
In 1995, the Amsterdam Police
captured a PC in possession of one
organized crime member. The PC
contained an encrypted partition,
which they were able to recover
only in 1997.
Illustration 8
An encryption case occurring in
Vilseck, West Germany involved
theft, fraud, and embezzlement of
U.S. defense contractor and U.S.
government funds from 1986 to
1988.
The accused had stored financial
records relating to the crimes on a
personal computer, the hard disk of
which had been password
protected.
The police used hacking software to
defeat the password protection, only
to find that some of the files listed in
the directory had been encrypted.
They then found the encryption
program on the hard disk and used
brute force tools to decrypt the files.
Illustration 9
The Dallas Police Department in the
USA encountered encryption in the
investigation of a drug ring, which
was operating in several states of
the USA and dealing in Ecstasy.
A member of the ring, residing
within their jurisdiction, had
encrypted his address book. He
turned over the password, enabling
the police to decrypt the file.
Meanwhile, however, the accused
was out on bail and alerted his
associates, so the decrypted
information was not as useful as it
might have been.
The police noted that Ecstasy
dealers were more knowledgeable
about computers when compared
with other types of drug dealers,
most likely because they were
younger and better educated.
Illustration 10
Kevin Poulson was a skilled hacker
who rigged radio contests and
burglarized telephone-switching
offices and hacked into the
telephone network in order to
determine whose phone was being
tapped and to install his own phone
tapping devices.
Poulson had encrypted files
documenting everything from the
phone tapping he had discovered to
the dossiers he had compiled about
his enemies. The files had been
encrypted several times using the
Data Encryption Standard.
A US Department of Energy
supercomputer took several months
to find the key, at a cost of millions
of dollars. The result yielded nearly
ten thousand pages of evidence.
Illustration 11
The mother of a 15-year old boy
filed a complaint against an adult
who had sold her son US $ 1000
worth of hardware and software for
one dollar.
The man had also given the boy
lewd pictures on floppy disks.
The man subsequently mailed the
boy pornographic material on floppy
disks and sent pornographic files
over the Internet.
When the accused was arrested it
was found out that he had
encrypted a directory on the system
using PGP. The police were never
able to decrypt the files.
Cyber Pornography
Cyber pornography is believed to be one of the largest businesses on the
Internet today. The millions of pornographic websites that flourish on the
Internet are testimony to this. While pornography per se is not illegal in
many countries, child pornography is strictly illegal in most nations today.
Cyber pornography covers pornographic websites, pornographic
magazines produced using computers (to publish and print the material)
and the Internet (to download and transmit pornographic pictures,
photos, writings etc).
Illustration 1
A school student from Delhi (India),
who was regularly teased for having
a pockmarked face, used a free
hosting provider to create
www.amazing-gents.8m.net.
He regularly uploaded “morphed”
photographs of teachers and girls
from his school onto the website.
He was arrested when the father of
one of the victims reported the case
to the police.
Illustration 2
The CEO of online auction website
bazee.com (a part of the ebay
group) was arrested by the Delhi
police for violating India’s strict laws
on cyber pornography. An
engineering student was using the
bazee website to sell a video
depicting two school students
having sexual intercourse.
Bazee.com was held liable for
distributing porn and hence the
CEO was arrested.
Illustration 3
The CEO of a software company in
Pune (India) was arrested for
sending highly obscene emails to a
former employee.
Sale of Illegal Articles
It is becoming increasingly common to find cases where sale of illegal
articles such as narcotics drugs, weapons, wildlife etc. is being facilitated
by the Internet. Information about the availability of the products for sale
is being posted on auction websites, bulletin boards etc.
It is practically impossible to control
or prevent a criminal from setting up
a website to transact in illegal
articles. Additionally, there are
several online payment gateways
that can transfer money around the
world at the click of a button.
The Internet has also created a marketplace for the sale of unapproved
drugs, prescription drugs dispensed without a valid prescription, or
products marketed with fraudulent health claims.
Many sites focus on selling
prescription drugs and are referred
to by some as “Internet
pharmacies.” These sites offer for
sale either approved prescription
drug products, or in some cases,
unapproved, illegal versions of
prescription drugs. This poses a
serious potential threat to the health
and safety of patients.
The broad reach, relative
anonymity, and ease of creating
new or removing old websites,
poses great challenges for law
enforcement officials.
Illustration
In March 2007, the Pune rural
police cracked down on an illegal
rave party and arrested hundreds of
illegal drug users. The social
networking site Orkut.com is
believed to be one of the modes of
communication for gathering people
for the illegal “drug” party.
Online Gambling
There are thousands of websites that offer online gambling. The special
issue with online gambling is that it is legalised in several countries. So
legally the owners of these websites are safe in their home countries.
The legal issues arise when a person residing in a foreign country like
India (where such websites are illegal) gambles on such a website.
Illustration
The website ladbrokes.com
permits users to gamble on a
variety of sports such as cricket,
football, tennis, golf, motor racing,
ice hockey, basketball, baseball,
darts, snooker, boxing, athletics,
rugby, volleyball, motor cycling etc.
Additionally it also features an
online casino. The website has no
technical measures in place to
prohibit residents of certain
countries (where online gambling is
illegal) from betting at their website.
Intellectual Property Crimes
These include software piracy, copyright infringement, trademarks
violations, theft of computer source code etc.
Illustration 1
A software professional from
Bangalore (India) was booked for
stealing the source code of a
product being developed by his
employers. He started his own
company and allegedly used the
stolen source code to launch a new
software product.
Illustration 2
In 2003, a computer user in China
obtained the source code of a
popular game - LineageII from an
unprotected website. This
proprietary code was then sold to
several people in 2004. One of
those people set up a website,
www.l2extreme.com, to offer the
“Lineage” game at a discount.
Despite legal warnings from the
South Korean company that owned
the Lineage source code, the
suspect did not shut down the site.
He rented powerful servers -
enough to accommodate 4,000
simultaneous gamers - and solicited
donations from users to help defray
the costs.
The loss in potential revenues for
the South Korean company was
estimated at $750,000 a month. The
US FBI arrested the suspect and
the website was shut down.
Email Spoofing
A spoofed email is one that appears to originate from one source but
actually has been sent from another source e.g Pooja has an e-mail
address pooja@asianlaws.org.
Her ex-boyfriend, Sameer spoofs her e-mail and sends obscene
messages to all her acquaintances. Since the e-mails appear to have
originated from Pooja, her friends may take offence and relationships
may be spoiled for life.
Illustration 1
In an American case, a teenager
made millions of dollars by
spreading false information about
certain companies whose shares he
had short sold.
This misinformation was spread by
sending spoofed emails, purportedly
from news agencies like Reuters, to
share brokers and investors who
were informed that the companies
were doing very badly.
Even after the truth came out the
values of the shares did not go back
to the earlier levels and thousands
of investors lost a lot of money.
Illustration 2
A branch of the erstwhile Global
Trust Bank in India experienced a
run on the bank. Numerous
customers decided to withdraw all
their money and close their
accounts.
An investigation revealed that
someone had sent out spoofed
emails to many of the bank’s
customers stating that the bank was
in very bad shape financially and
could close operations at any time.
The spoofed email appeared to
have originated from the bank itself.
Forgery
Counterfeit currency notes, postage and revenue stamps, mark sheets,
academic certificates etc are made by criminals using sophisticated
computers, printers and scanners.
Illustration 1
In October 1995, Economic
Offences Wing of Crime Branch,
Mumbai (India), seized over 22,000
counterfeit share certificates of eight
reputed companies worth Rs. 34.47
crores. These were allegedly
prepared using Desk Top
Publishing Systems.
Illustration 2
Abdul Kareem Telgi, along with
several others, was convicted in
India on several counts of
counterfeiting stamp papers and
postage stamps totalling several
billion rupees.
Cyber Defamation
This occurs when defamation takes place with the help of computers and
/ or the Internet. e.g. Sameer publishes defamatory matter about Pooja
on a website or sends e-mails containing defamatory information to
Pooja’s friends.
Illustration 1
Abhishek, a teenaged student was
arrested by the Thane police in
India following a girl’s complaint
about tarnishing her image in the
social networking site Orkut.
Abhishek had allegedly created a
fake account in the name of the girl
with her mobile number posted on
the profile.
The profile had been sketched in
such a way that it drew lewd
comments from many who visited
her profile. The Thane Cyber Cell
tracked down Abhishek from the
false e-mail id that he had created
to open up the account.
Illustration 2
The Aurangabad bench of the
Bombay high court issued a notice
to Google.com following a public
interest litigation initiated by a
young lawyer.
The lawyer took exception to a
community called ‘We hate India’,
owned by someone who identified
himself as Miroslav Stankovic. The
community featured a picture of the
Indian flag being burnt.
Illustration 3
Unidentified persons posted
obscene photographs and contact
details of a Delhi school girl.
Suggestive names like ’sex teacher’
were posted on the profile.
The matter came to light after the
girl’s family started receiving vulgar
calls referring to Orkut.
Cyber Stalking
Cyber stalking refers to the use of the Internet, e-mail, or other electronic
communications devices to stalk another person.
Stalking generally involves harassing or threatening behaviour that an
individual engages in repeatedly, such as following a person, appearing
at a person's home or place of business, making harassing phone calls,
leaving written messages or objects, or vandalizing a person's property.
Most stalking laws require that the perpetrator make a credible threat of
violence against the victim; others include threats against the victim's
immediate family.
Illustration 1
In the first successful prosecution
under the California (USA) cyber
stalking law, prosecutors obtained a
guilty plea from a 50-year-old
former security guard who used the
Internet to solicit the rape of a
woman who rejected his romantic
advances.
He terrorized the 28-year-old victim
by impersonating her in various
Internet chat rooms and online
bulletin boards, where he posted,
along with her telephone number
and address, messages that she
fantasized about being raped.
On at least six occasions,
sometimes in the middle of the
night, men knocked on the woman's
door saying they wanted to rape
her.
Illustration 2
An honours graduate from the
University of San Diego in USA
terrorized five female university
students over the Internet for more
than a year.
The victims received hundreds of
violent and threatening e-mails,
sometimes receiving four or five
messages a day.
The student, who pleaded guilty,
told the police that he had
Asian School of Cyber Laws

committed the crimes because he
thought the women were laughing
at him and causing others to ridicule
him. In reality, the victims had never
met him.
Illustration 3
In 2005, a minor from
Massachusetts (USA) was
convicted in connection with
approximately $1 million in victim
damages.
Over a 15-month period, he had
hacked into Internet and telephone
service providers, stolen an
individual’s personal information
and posted it on the Internet, and
made bomb threats to many high
schools.
Web defacement
Website defacement is usually the substitution of the original home page
of a website with another page (usually pornographic or defamatory in
nature) by a hacker.
Religious and government sites are regularly targeted by hackers in
order to display political or religious beliefs. Disturbing images and
offensive phrases might be displayed in the process, as well as a
signature of sorts, to show who was responsible for the defacement.
Websites are not only defaced for political reasons, many defacers do it
just for the thrill. For example, there are online contests in which hackers
are awarded points for defacing the largest number of web sites in a
specified amount of time. Corporations are also targeted more often than
other sites on the Internet and they often seek to take measures to
protect themselves from defacement or hacking in general.
Web sites represent the image of a company or organisation and these
are therefore especially vulnerable to defacement. Visitors may lose faith
in sites that cannot promise security and will become wary of performing
online transactions. After defacement, sites have to be shut down for
repairs, sometimes for an extended period of time, causing expenses
and loss of profit.
Illustration 1
Mahesh Mhatre and Anand Khare
(alias Dr Neukar) were arrested in
2002 for allegedly defacing the
website of the Mumbai Cyber Crime
Cell.
They had allegedly used password
cracking software to crack the FTP
password for the police website.
They then replaced the homepage
of the website with pornographic
content. The duo was also charged
with credit card fraud for using 225
credit card numbers, mostly
belonging to American citizens.
Illustration 2
In 2001, over 200 Indian websites
were hacked into and defaced. The
hackers put in words like bugz,
death symbol, Paki-king and
allahhuakbar.
In the case of 123medicinindia.com,
a message was left behind which
said – “Catch me if uuu can my
Asian School of Cyber Laws

deraz lazy adminzzz” – challenging
the system administrators to trace
the miscreants.
The offenders were allegedly a
group of hackers who go by the
name of ‘Pakistani Cyber Warriors’.
Illustration 3
In 2006, a Turkish hacker using the
handle iSKORPiTX was able to
breach the security of a group of
web servers, containing more than
38,500 web sites in less than a day!
Illustration 4
The first Defacers Challenge took
place on Sunday, July 6, 2003.
There was a special prize for the
first contestant to deface 6,000 web
sites.
The contest was conducted over a
six-hour period. Points were
awarded based on the server’s
operating system.
Windows: 1 point,
Linux: 2 points,
BSD: 2 points,
AIX: 3 points,
HP-UX: 5 points
Macintosh: 5 points
Email Bombing
Email bombing refers to sending a large number of emails to the victim
resulting in the victim’s email account (in case of an individual) or mail
servers (in case of a company or an email service provider) crashing.
Email bombing is a type of denial-of-service attack. A denial-of-service
attack is one in which a flood of information requests is sent to a server,
bringing the system to its knees and making the server difficult to access.
Illustration 1
A British teenager was cleared of
launching a denial-of-service attack
against his former employer, in a
ruling under the UK Computer
Misuse Act.
The teenager was accused of
sending 5 million e-mail messages
to his ex-employer that caused the
company's e-mail server to crash.
The judge held that the UK
Computer Misuse Act does not
specifically include a denial-ofservice attack as a criminal offence.
Illustration 2
In one case, a foreigner who had
been residing in Simla, India for
almost 30 years wanted to avail of a
scheme introduced by the Simla
Housing Board to buy land at lower
rates. When he made an application
it was rejected on the grounds that
the scheme was available only for
citizens of India.
He decided to take his revenge.
Consequently, he sent thousands of
mails to the Simla Housing Board
and repeatedly kept sending e-mails
till their servers crashed.
Data Diddling
One of the most common forms of computer crime is data diddling -
illegal or unauthorized data alteration. These changes can occur before
and during data input or before output. Data diddling cases have affected
banks, payrolls, inventory records, credit records, school transcripts and
virtually all other forms of data processing known.
Illustration 1
The NDMC Electricity Billing Fraud
Case that took place in 1996 is a
typical example. The computer
network was used for receipt and
accounting of electricity bills by the
New Delhi Municipal Council.
Collection of money, computerized
accounting, record maintenance
and remittance in the bank were
exclusively left to a private
contractor who was a computer
professional.
He misappropriated huge amount of
funds by manipulating data files to
show less receipt and bank
remittance.
Illustration 2
A keyboard operator processing
orders at an Oakland USA
department store changed some
delivery addresses and diverted
several thousand dollars worth of
store goods into the hands of
accomplices.
Illustration 3
A ticket clerk at the Arizona
Veterans' Memorial Coliseum in
USA issued full-price basketball
tickets, sold them and then, tapping
out codes on her computer
keyboard, recorded the transactions
as half-price sales.
Salami Attacks
These attacks are used for committing financial crimes. The key here is
to make the alteration so insignificant that in a single case it would go
completely unnoticed.
For instance, a bank employee inserts a program, into the bank’s
servers, that deducts a small amount of money (say Rs. 2 a month) from
the account of every customer. No account holder will probably notice
this unauthorized debit, but the bank employee will make a sizeable
amount of money every month.
The attack is called “salami attack” as it is analogous to slicing the data
thinly, like a salami.
Illustration 1
Four executives of a rental-car
franchise in Florida USA defrauded
at least 47,000 customers using a
salami technique.
They modified a computer billing
program to add five extra gallons to
the actual gas tank capacity of their
vehicles.
From 1988 through 1991, every
customer who returned a car
without topping it off ended up
paying inflated rates for an inflated
total of gasoline.
The thefts ranged from $2 to $15
per customer - difficult for the
victims to detect.
Illustration 2
In January 1997, Willis Robinson of
Maryland USA, was sentenced to
10 years in prison for “having
reprogrammed his Taco Bell driveup-window cash register - causing it
to ring up each $2.99 item internally
as a 1-cent item, so that he could
pocket $2.98 each time”.
The management assumed the
error was hardware or software and
only caught the perpetrator when he
bragged about his crime to coworkers.

In Los Angeles USA four men were
charged with fraud for allegedly
installing computer chips in gasoline
pumps that cheated consumers by
overstating the amounts pumped.
The problem came to light when an
increasing number of consumers
claimed that they had been sold
more gasoline than the capacity of
their gas tanks!
However, the fraud was difficult to
prove initially because the
perpetrators programmed the chips
to deliver exactly the right amount of
gasoline when asked for five- and
10-gallon amounts (precisely the
amounts typically used by
inspectors).
Denial of Service Attack
Denial of Service attacks (DOS attacks) involve flooding a computer with
more requests than it can handle. This causes the computer (e.g. a web
server) to crash and results in authorized users being unable to access
the service offered by the computer.
Another variation to a typical denial of service attack is known as a
Distributed Denial of Service (DDoS) attack wherein the perpetrators are
many and are geographically widespread.
Illustration 1
A series of distributed denial of
service attacks in February 2000
crippled many popular websites
including yahoo.com, amazon.com
and cnn.com
Illustration 2
A series of more than 125 separate
but coordinated denial of service
attacks hit the cyber infrastructure
of Estonia in early 2007.
The attacks were apparently
connected with protests against the
Estonian government's decision to
remove a Soviet-era war memorial
from the capital city.
It is suspected that the attacks were
carried out by Russian hackers. The
attack lasted several days.
Virus / Worm Attacks
Computer viruses are small software programs that are designed to
spread from one computer to another and to interfere with computer
operation. A virus might corrupt or delete data on the victim’s computer,
use the victim’s e-mail program to spread itself to other computers, or
even erase everything on the victim’s hard disk.
Viruses are most easily spread by attachments in e-mail messages or
instant messaging messages. Viruses can be disguised as attachments
of funny images, greeting cards, or audio and video files. Viruses can
also spread through downloads on the Internet. They can be hidden in
illicit software or other files or programs.
Worms, unlike viruses do not need the host to attach themselves to.
They merely make functional copies of themselves and do this
repeatedly till they eat up all the available space on a computer’s
memory.
Brain (in its first incarnation written in January 1986) is considered to be
the first computer virus for the PC. The virus is also known as Lahore,
Pakistani, Pakistani Brain, Brain-A and UIUC. The virus was written by
two brothers, Basit and Amjad Farooq Alvi, who lived in Lahore,
Pakistan. The brothers told TIME magazine they had written it to protect
their medical software from piracy and was supposed to target copyright
infringers only.
The virus came complete with the brothers' address and three phone
numbers, and a message that told the user that their machine was
infected and for inoculation the user should call them.
When the brothers began to receive a large number of phone calls from
people in USA, Britain, and elsewhere, demanding them to disinfect their
machines, the brothers were stunned and tried to explain to the outraged
callers that their motivation had not been malicious.
They ended up having to get their phone lines cut off and regretted that
they had revealed their contact details in the first place. The brothers are
still in business in Pakistan as internet service providers in their company
called Brain Limited.

The VBS_LOVELETTER virus
(better known as the Love Bug or
the ILOVEYOU virus) was
reportedly written by a Filipino
undergraduate. In May 2000, this
deadly virus became the world’s
most prevalent virus. Losses
incurred during this virus attack
were pegged at US $ 10 billion.
VBS_LOVELETTER utilized the
addresses in Microsoft Outlook and
e-mailed itself to those addresses.
The e-mail, which was sent out, had
“ILOVEYOU” in its subject line. The
attachment file was named “LOVELETTER-FOR-YOU.TXT.vbs”.
People wary of opening e-mail
attachments were conquered by the
subject line and those who had
some knowledge of viruses, did not
notice the tiny .vbs extension and
believed the file to be a text file. The
message in the e-mail was “kindly
check the attached LOVELETTER
coming from me”.

Probably the world’s most famous
worm was the Internet worm let
loose on the Internet by Robert
Morris sometime in 1988. The
Internet was, then, still in its
developing years and this worm,
which affected thousands of
computers, almost brought its
development to a complete halt. It
took a team of experts almost three
days to get rid of the worm and in
the meantime many of the
computers had to be disconnected
from the network.

Logic bombs are event dependent
programs. This implies that these
programs are created to do
something only when a certain
event (known as a trigger event)
occurs. e.g. even some viruses may
be termed logic bombs because
they lie dormant all through the year
and become active only on a
particular date (like the Chernobyl
virus).
Trojans and Keyloggers
A Trojan, as this program is aptly called, is an unauthorized program
which functions from inside what seems to be an authorized program,
thereby concealing what it is actually doing.
Keyloggers are regularly used were to log all the strokes a victim makes
on the keyboard. This assumes sinister proportions, if a key logger is
installed on a computer which is regularly used for online banking and
other financial transactions. Key-loggers are most commonly found in
public computers such as those in cyber cafes, hotels etc. Unsuspecting
victims also end up downloading spyware when they click on “friendly”
offers for free software.

A young lady reporter was working
on an article about online
relationships. The article focused on
how people can easily find
friendship and even love on the
Internet. During the course of her
research she made a lot of online
friends. One of these ‘friends’
managed to infect her computer
with a Trojan.
This young lady stayed in a small
one bedroom apartment and her
computer was located in one corner
of her bedroom. Unknown to her,
the Trojan would activate her web
camera and microphone even when
the Internet was switched off. A
year later she realized that
hundreds of her pictures were
posted on pornographic sites
around the world!

The network administrator in a
global bank received a beautifully
packed CD ROM containing
“security updates” from the
company that developed the
operating system that ran his bank’s
servers.
He installed the “updates” which in
reality was Trojanized software. 3
years later, the effects were still
being felt in the bank’s system!
Internet Time Theft
This connotes the usage by an unauthorized person of the Internet hours
paid for by another person.
Illustration
In May 2000, the Delhi police
arrested an engineer who had
misused the login name and
password of a customer whose
Internet connection he had set up.
The case was filed under the Indian
Penal Code and the Indian
Telegraph Act.
Web Jacking
Just as conventional hijacking of an airplane is done by using force,
similarly web jacking means forcefully taking over control of a website.
The motive is usually the same as hijacking – ransom. The perpetrators
have either a monetary or political purpose which they try to satiate by
holding the owners of the website to ransom.
This occurs when someone forcefully takes control of a website (by
cracking the password and later changing it). The actual owner of the
website does not have any more control over what appears on that
website.
How does web jacking take place?
The administrator of any website
has a password and a username
that only he (or someone authorized
by him) may use to upload files from
his computer on the web server
(simply put, a server is a powerful
computer) where his website is
hosted.
Ideally, this password remains
secret with the administrator. If a
hacker gets hold of this username
and password, then he can pretend
to be the administrator.
Computers don’t recognize people –
only usernames and passwords.
The web server will grant control of
the website to whoever enters the
correct password and username
combination.
There are many ways in which a
hacker may get to know a
password, the most common being
password cracking wherein a
“cracking software” is used to guess
a password. Password cracking
attacks are most commonly of two
types.
The first one is known as the
dictionary attack. In this type of
attack the software will attempt all
the words contained in a predefined
dictionary of words.
For example, it may try Rahim,
Rahul, Rakesh, Ram, Reema,
Reena … in a predefined dictionary
of Indian names. These types of
dictionaries are readily available on
the Internet.
The other form of password
cracking is by using ‘brute force’. In
this kind of attack the software tries
to guess the password by trying out
all possible combinations of
numbers, symbols, letters till the
correct password is found. For
example, it may try out password
combinations like abc123,
acbd5679, sdj#%^, weuf*(-)*.
Some software, available for
password cracking using the brute
force technique, can check a huge
number of password combinations
per second.
When compared with a dictionary
attack, a brute force attack takes
more time, but it is definitely more
successful.
Illustration
In an incident reported in the USA,
the owner of a hobby website for
children received an e-mail
informing her that a group of
hackers had gained control over her
website. They demanded a ransom
of 1 million dollars from her.
The owner, a schoolteacher, did not
take the threat seriously. She felt
that it was just a scare tactic and
ignored the e-mail.
It was three days later that she
came to know, following many
telephone calls from all over the
country, that the hackers had web
jacked her website. Subsequently,
they had altered a portion of the
website which was entitled ‘How to
have fun with goldfish’.
In all the places where it had been
mentioned, they had replaced the
word ‘goldfish’ with the word
‘piranhas’.
Piranhas are tiny but extremely
dangerous flesh-eating fish. Many
children had visited the popular
website and had believed what the
contents of the website suggested.
These unfortunate children followed
the instructions, tried to play with
piranhas, which they bought from
pet shops, and were very seriously
injured!
Email Frauds
Dear Mr. Justin Williams, I'm Vikas Manjit Singh from
Punjab (India). I belong to a city named Ludhiana.
Mr. Williams, I am having a brother in Canada who is also
named Justin Williams. He was adopted from my parents
by some Mr. William Ram of Welland. Me and my mum
came over to Canada to leave Justin to his new family
(William Ram's Family). It happened in June 1985.
So Mr. Justin Williams, if you are the same person I'm
talking about. Then please give me some time so that I
can let you know the realities.
Imagine the thoughts going through Mr. Justin William’s head after
reading this email. Is he really adopted? Where are his birth parents? Is
this email from his birth brother?
In reality, this is a scam email originating from a college in Sangroor
(India)! Canadian citizens are targeted with these emails. If the targets
start believing the sender to be their brother, they are asked to send
money so that their “brother” can travel to Canada with the proof of the
victim’s adoption!
This is just one of the hundreds of email scams being perpetrated on the
Internet. These scams are commonly referred to as Nigerian 419 scams.
These scam emails are believed to originate from Nigeria and section
419 of the Nigerian Penal Code relates to cheating (like the famous
section 420 of the Indian Penal Code).
The 419 letter scams originated in the early 1980s as the oil-based
economy of Nigeria went downhill. In the 1990s, letter scams gave way
to email scams.
In 2007, Asian School of Cyber Laws conducted a 3 month intensive
investigation of hundreds of scam emails. The results were very
surprising to say the least. Less than 10% of these emails had actually
originated from Nigeria!
A majority of these emails (more than 60%) have originated from Israel,
followed by the Netherlands, UK and other European countries. The
“birth brother” email was the only one originating from India.
Most of these scam emails promise the receiver millions (or sometimes
billions) of dollars. Most commonly the email says that some rich African
bureaucrat or businessman or politician has died and left behind a lot of
money.
The scamster states that the Government is going to confiscate the
money. The only way out is to transfer the money to the bank account of
the email recipient. All that the email recipient has to do is send his bank
account details. For this a generous fee of a few million dollars will be
paid!
If someone actually falls for this scam and provides the bank details, he
is sent some official looking documents relating to the bank transfer of a
huge sum of money. Once the victim is convinced of the “genuineness”
of the transaction, something appears to go wrong.
The victim is informed that a small amount of money (ranging from US$
100 to 2500) is needed for bank charges or other paper work. This
money is the motive behind the elaborate scam. Once the victim pays
this money, the scamster disappears from the scene.
The lottery scam emails inform the recipient that he has won a million
dollar lottery run by Microsoft, Yahoo or some other well known global
company. The winner is asked to provide his bank details and pay a
small sum for bank charges and other processing fees.
Another scam email begins with “This is to inform you that we are in
possession of a consignment, deposited by British National Lottery which
is to be couriered to you”. The email asks for 470 pounds to be sent to
the courier company so that the cheque for the lottery prize can be sent.
Another scam email comes with the subject line “Blessed is the hand that
giveth”. The sender claims to be a widow on her deathbed. She wants to
donate her wealth to someone who will pray for her.
Another scam email comes from an “employee of the Euro Lottery”. The
“employee” claims to be in a position to carry out a lottery fraud and is
willing to share the money with the email recipient.
What is common in all these scams is that scanned versions of official
documents are emailed to potential victims. Once the victim is convinced
of the genuineness of the transaction, a small fee is requested for
meeting bank charges / legal fees / courier charges etc. It is this small
fee that is the motive behind the scam.
It is believed that thousands of people are defrauded of billions of dollars
every year through these scams.
Illustration 1
In 2005, an Indian businessman
received an email from the Vice
President of a major African bank
offering him a lucrative contract in
return for a kickback of Rs 1 million.
The businessman had many
telephonic conversations with the
sender of the email. He also verified
the email address of the ‘Vice
President’ from the website of the
bank and subsequently transferred
the money to the bank account
mentioned in the email. It later
turned out that the email was a
spoofed one and was actually sent
by an Indian based in Nigeria.
Illustration 2
A new type of scam e-mail
threatens to kill recipients if they do
not pay thousands of dollars to the
sender, who purports to be a hired
assassin.
Replying to the e-mails just sends a
signal to senders that they’ve
reached a live account. It also
escalates the intimidation.
In one case, a recipient threatened
to call authorities. The scammer,
who was demanding $20,000,
reiterated the threat and sent some
personal details about the
recipient—address, daughter’s full
name etc. He gave an ultimatum:
“TELL ME NOW ARE YOU READY
TO DO WHAT I SAID OR DO YOU
WANT ME TO PROCEED WITH
MY JOB? ANSWER YES/NO AND
DON’T ASK ANY QUESTIONS!!!”
Some emails claim to be from the
FBI in London and inform recipients
that an arrest was made in the
case.
The e-mail says the recipient’s
information was found with the
suspect and that they should reply
to assist in the investigation. These
emails are part of the scam!
Cyber Terrorism
Computer crime has hit mankind with unbelievable severity. Computer
viruses, worms, Trojans, denial of service attacks, spoofing attacks and
e-frauds have taken the real and virtual worlds by storm.
However, all these pale in the face of the most dreaded threat – that of
cyber terrorism.
Asian School of Cyber Laws has defined cyber terrorism as:
Cyber terrorism is the premeditated use of disruptive
activities, or the threat thereof, in cyber space, with the
intention to further social, ideological, religious, political or
similar objectives, or to intimidate any person in furtherance
of such objectives.
Illustration 1
In 1996, a computer hacker
allegedly associated with the White
Supremacist movement temporarily
disabled a US based Internet
Service Provider (ISP) and
damaged part of its record keeping
system.
The ISP had attempted to stop the
hacker from sending out worldwide
racist messages under the ISP's
name. The hacker signed off with
the threat, "you have yet to see true
electronic terrorism. This is a
promise."
Illustration 2
In 1998, Spanish protestors
bombarded the Institute for Global
Communications (IGC) with
thousands of bogus e-mail
messages. E-mail was tied up and
undeliverable to the ISP's users,
and support lines were tied up with
people who couldn't get their mail.
The protestors also spammed IGC
staff and member accounts,
clogged their Web page with bogus
credit card orders, and threatened
to employ the same tactics against
organizations using IGC services.
They demanded that IGC stop
hosting the website for the Euskal
Herria Journal, a New York-based
publication supporting Basque
independence.
Protestors said IGC supported
terrorism because a section on the
Web pages contained materials on
the terrorist group ETA, which
claimed responsibility for
assassinations of Spanish political
and security officials, and attacks on
military installations. IGC finally
relented and pulled the site because
of the "mail bombings."

In 1998, ethnic Tamil guerrillas
swamped Sri Lankan embassies
with 800 e-mails a day over a twoweek period.
The messages read "We are the

authorities characterized it as the
first known attack by terrorists
against a country's computer
systems.

During the Kosovo conflict in 1999,
NATO computers were blasted with
e-mail bombs and hit with denial-ofservice attacks by hacktivists
protesting the NATO bombings.
In addition, businesses, public
organizations, and academic
institutes received highly politicized
virus-laden e-mails from a range of
Eastern European countries,
according to reports. Web
defacements were also common.

Since December 1997, the
Electronic Disturbance Theater
(EDT) has been conducting Web
sit-ins against various sites in
support of the Mexican Zapatistas.
At a designated time, thousands of
protestors point their browsers to a
target site using software that floods
the target with rapid and repeated
download requests.
EDT's software has also been used
by animal rights groups against
organizations said to abuse
animals.
Electrohippies, another group of
hacktivists, conducted Web sit-ins
against the WTO when they met in
Seattle in late 1999.

obscene pictures.
Use of encryption by terrorists
A disturbing trend that is emerging nowadays is the increasing use of
encryption, high-frequency encrypted voice/data links, encryption
software like Pretty Good Privacy (PGP) etc by terrorists and members of
organized crime cartels.
Strong encryption is the criminal’s best friend and the policeman’s worst
enemy.
Illustration 1
Leary, who was sentenced to 94
years in prison for setting off fire
bombs in the New York (USA)
subway system in 1995, had

The Cali cartel is reputed to be
using
• sophisticated encryption to
conceal their telephone
communications,
• radios that distort voices,
• video phones which provide
visual authentication of the
caller's identity, and
• instruments for scrambling
transmissions from
computer modems.

On March 20, 1995, the Aum
Supreme Truth cult dropped bags of
sarin nerve gas in the Tokyo

injuring 6,000 more.
Members of the cult had developed
many chemical and biological
weapons, including Sarin, VX,
Mustard gas, Cyanide, botulism,
anthrax and Q fever.

It is believed that preparations were
underway to develop nuclear
capability. The cult was also
believed to be developing a "death
ray" that could destroy all life!
The records of the cult had been
stored in encrypted form (using the
RSA algorithm) on computers.
The enforcement authorities were
able to decrypt the information as
the relevant private key was found
in a floppy disk seized from the
cult’s premises. The encrypted
information related to plans of the
cult to cause mass deaths in Japan
and USA.
Illustration 5
In 1997, a Bolivian terrorist
organization had assassinated four
U.S. army personnel.
A raid on one of the hideouts of the
terrorists yielded information
encrypted using symmetric
encryption.
A 12-hour brute force attack
resulted in the decryption of the
information and subsequently led to
one of the largest drug busts in
Bolivian history and the arrest of the
terrorists.

James Bell was arrested for
violating internal revenue laws of
the USA. He did this by:
ƒ collecting the names and
home addresses of agents
and employees of the
Internal Revenue Service
(IRS) of the USA in order to
intimidate them
ƒ soliciting people to join in a
scheme known as
"Assassination Politics".
Under this scheme those
who killed selected
government employees,
including tax collectors,
would be rewarded;
ƒ using false Social Security
Numbers to hide his assets
and avoid taxes;
ƒ contaminating an area
outside IRS premises in
many states of the USA with
Mercaptan (a stink gas).
Investigators found on his computer
documents relating to a plan to
destroy electronic equipment with
nickel-plated carbon fiber.
They also found an invoice for the
purchase of the fiber at his
residence, and a bundle of the
material at the residence of his
associate, Robert East. Bell had
exchanged PGP-encrypted e-mail
messages with some of his
associates.
As part of his plea bargain, he
turned over the passphrase to his
private key. This allowed
investigators to decrypt messages
that he had received.

Dutch organized crime syndicates
use PGP and PGPfone to encrypt
their communications. They also
use palmtop computers installed
with Secure Device, a Dutch
software product for encrypting data
with International Data Encryption
Algorithm (IDEA).
In 1995, the Amsterdam Police
captured a PC in possession of one
organized crime member. The PC
contained an encrypted partition,
which they were able to recover
only in 1997.

An encryption case occurring in
Vilseck, West Germany involved
theft, fraud, and embezzlement of
U.S. defense contractor and U.S.
government funds from 1986 to
1988.
The accused had stored financial
records relating to the crimes on a
personal computer, the hard disk of
which had been password
protected.
The police used hacking software to
defeat the password protection, only
to find that some of the files listed in
the directory had been encrypted.
They then found the encryption
program on the hard disk and used
brute force tools to decrypt the files.
Illustration 9
The Dallas Police Department in the
USA encountered encryption in the
investigation of a drug ring, which
was operating in several states of
the USA and dealing in Ecstasy.
A member of the ring, residing
within their jurisdiction, had
encrypted his address book. He
turned over the password, enabling
the police to decrypt the file.
Meanwhile, however, the accused
was out on bail and alerted his
associates, so the decrypted
information was not as useful as it
might have been.
The police noted that Ecstasy
dealers were more knowledgeable
about computers when compared
with other types of drug dealers,
most likely because they were
younger and better educated.

Kevin Poulson was a skilled hacker
who rigged radio contests and
burglarized telephone-switching
offices and hacked into the
telephone network in order to
determine whose phone was being
tapped and to install his own phone
tapping devices.
Poulson had encrypted files
documenting everything from the
phone tapping he had discovered to
the dossiers he had compiled about
his enemies. The files had been
encrypted several times using the
Data Encryption Standard.
A US Department of Energy
supercomputer took several months
to find the key, at a cost of millions
of dollars. The result yielded nearly
ten thousand pages of evidence.

The mother of a 15-year old boy
filed a complaint against an adult
who had sold her son US $ 1000
worth of hardware and software for
one dollar.
The man had also given the boy
lewd pictures on floppy disks.
The man subsequently mailed the
boy pornographic material on floppy
disks and sent pornographic files
over the Internet.
When the accused was arrested it
was found out that he had
encrypted a directory on the system
using PGP. The police were never
able to decrypt the files.
Financial Crimes
Money is the most common motive behind all crime. The same is also
true for cyber crime. Globally it is being observed that more and more
cyber crimes are being committed for financial motives rather than for
“revenge” or for “fun”.
With the tremendous increase in the use of internet and mobile banking,
online share trading, dematerialization of shares and securities, this trend
is likely to increase unabated.
Financial crimes include cyber cheating, credit card frauds, money
laundering, hacking into bank servers, computer manipulation,
accounting scams etc.

Punjab National Bank in India was
cheated to the tune of Rs. 13.9
million through false debits and

The Hyderabad police in India
arrested an unemployed computer
operator and his friend, a steward in
a prominent five-star hotel, for
stealing and misusing credit card
numbers belonging to hotel
customers.
The steward noted down the
various details of the credit cards,
which were handed by clients of the
hotel for paying their bills. Then, he
passed all the details to his
computer operator friend who used
the details to make online
purchases on various websites.

In 2004, the US Secret Service
investigated and shut down an
online organization that trafficked in
around 1.7 million stolen credit
cards and stolen identity information
and documents.
This high-profile case, known as
“Operation Firewall,” focused on a
criminal organization of some 4,000
members whose Web site
functioned as a hub for identity theft
activity.

In 2003, a hacker was convicted in
the USA for causing losses of
almost $25 million. The defendant
pleaded guilty to numerous charges
of conspiracy, computer intrusion,
computer fraud, credit card fraud,
wire fraud, and extortion.
The hacker and his accomplices
from Russia had stolen usernames,
passwords, credit card information,
and other financial data by hacking
into computers of US citizens. They
would then extort money from those
victims with the threat of deleting
their data and destroying their
computer systems.
