Computer crime, or cybercrime,
is crime that involves a computer and a network. The computer may have
been used in the commission of a crime, or it may be the target.Debarati Halder
and K. Jaishankar define cybercrimes as: "Offences that are committed
against individuals or groups of individuals with a criminal motive to
intentionally harm the reputation of the victim or cause physical or mental
harm, or loss, to the victim directly or indirectly, using modern
telecommunication networks such as Internet (Chat rooms, emails, notice boards
and groups) and mobile phones (SMS/MMS)". Such crimes may threaten a
nation's security and financial health. Issues surrounding these types of
crimes have become high-profile, particularly those surrounding hacking, copyright
infringement, child pornography, and child grooming. There are also problems of
privacy when confidential information is intercepted or disclosed, lawfully or
otherwise. Debarati Halder and K. Jaishankar further define cybercrime from the
perspective of gender and defined 'cybercrime against women' as "Crimes
targeted against women with a motive to intentionally harm the victim
psychologically and physically, using modern telecommunication networks such as
internet and mobile phones"Internationally, both governmental and
non-state actors engage in cybercrimes, including espionage, financial theft,
and other cross-border crimes. Activity crossing international borders and
involving the interests of at least one nation state is sometimes referred to
as cyberwarfare. The international legal system is attempting to hold actors
accountable for their actions through the International Criminal Court. Fraud and financial crimes
Internet fraud.
Computer
fraud is any dishonest misrepresentation of fact intended to let another to do
or refrain from doing something which causes loss. In this context, the fraud
will result in obtaining a benefit by:
- Altering
in an unauthorized way. This requires little technical expertise and is
common form of theft by employees altering the data before entry or
entering false data, or by entering unauthorized instructions or using
unauthorized processes;
- Altering,
destroying, suppressing, or stealing output, usually to conceal
unauthorized transactions. This is difficult to detect;
- Altering
or deleting stored data;
Other
forms of fraud may be facilitated using computer systems, including bank fraud,
carding, identity theft, extortion, and theft of classified information.
A
variety of internet scams many based on phishing and social engineerins, target consumers and businesses.
Cyber terrorism
Government
officials and information technology security specialists have documented a
significant increase in Internet problems and server scans since early 2001.
But there is a growing concern among federal officials that such intrusions are
part of an organized effort by cyberterrorists, foreign intelligence services,
or other groups to map potential security holes in critical systems. A
cyberterrorist is someone who intimidates or coerces a government or
organization to advance his or her political or social objectives by launching
a computer-based attack against computers, networks, or the information stored
on them.
Cyberterrorism
in general, can be defined as an act of terrorism committed through the use of
cyberspace or computer resources (Parker 1983). As such, a simple propaganda in
the Internet, that there will be bomb attacks during the holidays can be
considered cyberterrorism. There are also hacking activities directed towards
individuals, families, organized by groups within networks, tending to cause
fear among people, demonstrate power, collecting information relevant for
ruining peoples' lives, robberies, blackmailing.
Cyberextortion
Cyberextortion
occurs when a website, e-mail server, or computer system is subjected to or
threatened with repeated denial of service or other attacks by malicious
hackers. These hackers demand money in return for promising to stop the attacks
and to offer "protection". According to the Federal Bureau of
Investigation, cyberextortionists are increasingly attacking corporate websites
and networks, crippling their ability to operate and demanding payments to
restore their service. More than 20 cases are reported each month to the FBI
and many go unreported in order to keep the victim's name out of the public
domain. Perpetrators typically use a distributed denial-of-service attack.
