Computer crime, or
cybercrime, is crime that involves a
computer and a
network.
[1] The computer may have been used in the commission of a crime, or it may be the target.
[2]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)".
[3] Such crimes may threaten a nation's security and financial health.
[citation needed] 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".
[3] 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.
[4] A report (sponsored by
McAfee) estimates that the annual damage to the global economy is at $445 billion;
[5] however, a Microsoft report shows that such survey-based estimates are "hopelessly flawed" and exaggerate the true losses by orders of magnitude.
[6][third-party source needed] Approximately $1.5 billion was lost in 2012 to online credit and debit card fraud in the US.
[7] In 2016, a study by Juniper Research estimated that the costs of cybercrime could be as high as 2.1 trillion by 2019.
[8][third-party source needed]Most measures show that the problem of cybercrime continues to worsen. However, Eric Jardine argues that the frequency, cost and severity of cybercrime cannot be well understood as counts expressed in absolute terms. Instead, these numbers need to be normalized around the growing size of cyberspace, in the same way that crime statistics in the physical world are expressed as a proportion of a population (i.e., 1.5 murders per 100,000 people). Jardine argues that, since cyberspace has been rapidly increasing in size each year, absolute numbers (i.e., a count saying there are 100,000 cyberattacks in 2015) present a worse picture of the security of cyberspace than numbers normalized around the actual size of the Internet ecosystem (i.e., a rate of cybercrime). His proposed intuition is that if cyberspace continues to grow, you should actually expect cybercrime counts to continue to increase because there are more users and activity online, but that as a proportion of the size of the ecosystem crime might actually be becoming less of a problem.
[9][third-party source needed]Classification[edit]
Computer crime encompasses a broad range of activities.
Fraud and financial crimes[edit]
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;
Cyber terrorism[edit]
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
[who?] 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 etc.
[citation needed]Cyberextortion[edit]
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.
[10]Cyberwarfare[edit]
Sailors analyze, detect and defensively respond to unauthorized activity within
U.S. Navy information systems and computer networks
The U.S.
Department of Defense (DoD) notes that the cyberspace has emerged as a national-level concern through several recent events of geo-strategic significance. Among those are included, the attack on
Estonia's infrastructure in 2007, allegedly by Russian hackers. "In August 2008, Russia again allegedly conducted cyberattacks, this time in a coordinated and synchronized kinetic and non-kinetic campaign against the country of
Georgia. Fearing that such attacks may become the norm in future warfare among nation-states, the concept of cyberspace operations impacts and will be adapted by warfighting military commanders in the future.
[12]Computer as a target[edit]
These crimes are committed by a selected group of criminals. Unlike crimes using the computer as a tool, these crimes require the technical knowledge of the perpetrators. As such, as technology evolves, so too does the nature of the crime. These crimes are relatively new, having been in existence for only as long as computers have—which explains how unprepared society and the world in general is towards combating these crimes. There are numerous crimes of this nature committed daily on the internet:
Crimes that primarily target computer networks or devices include:
Computer as a tool[edit]
When the individual is the main target of cybercrime, the computer can be considered as the tool rather than the target. These crimes generally involve less technical expertise. Human weaknesses are generally exploited. The damage dealt is largely psychological and intangible, making legal action against the variants more difficult. These are the crimes which have existed for centuries in the offline world. Scams, theft, and the likes have existed even before the development in high-tech equipment. The same criminal has simply been given a tool which increases his potential pool of victims and makes him all the harder to trace and apprehend.
[13]Crimes that use computer networks or devices to advance other ends include:
- Fraud and identity theft (although this increasingly uses malware, hacking and/or phishing, making it an example of both "computer as target" and "computer as tool" crime)
- Information warfare
- Phishing scams
- Spam
- Propagation of illegal obscene or offensive content, including harassment and threats
Phishing is mostly propagated via email. Phishing emails may contain links to other websites that are affected by malware.
[14] Or, they may contain links to fake
online banking or other websites used to steal private account information.
Obscene or offensive content[edit]
The content of websites and other electronic communications may be distasteful,
obscene or offensive for a variety of reasons. In some instances these communications may be legal.
The extent to which these communications are unlawful varies greatly between countries, and even within nations. It is a sensitive area in which the courts can become involved in arbitrating between groups with strong beliefs.
Harassment[edit]
Various aspects needed to be considered when understanding
harassment online.
Whereas content may be offensive in a non-specific way,
harassment directs obscenities and derogatory comments at specific individuals focusing for example on gender, race, religion, nationality, sexual orientation. This often occurs in chat rooms, through newsgroups, and by sending hate e-mail to interested parties. Harassment on the internet also includes
revenge porn.
There are instances where committing a crime using a computer can lead to an enhanced sentence. For example, in the case of
United States v. Neil Scott Kramer, Kramer was served an enhanced sentence according to the
U.S. Sentencing Guidelines Manual §2G1.3(b)(3)
[15] for his use of a
cell phone to "persuade, induce, entice, coerce, or facilitate the travel of, the minor to engage in prohibited sexual conduct." Kramer argued that this claim was insufficient because his charge included persuading through a computer device and his cellular phone technically is not a computer. Although Kramer tried to argue this point, U.S. Sentencing Guidelines Manual states that the term computer "means an electronic, magnetic, optical,
electrochemically, or other high speed data processing device performing logical, arithmetic, or storage functions, and includes any data storage facility or communications facility directly related to or operating in conjunction with such device."
[16]Harassment as defined in the U.S. computer statutes is typically distinct from cyberbullying, in that the former usually relates to a person's "use a computer or computer network to communicate obscene, vulgar, profane, lewd, lascivious, or indecent language, or make any suggestion or proposal of an obscene nature, or threaten any illegal or immoral act," while the latter need not involve anything of a sexual nature.
Although
freedom of speech is protected by law in most democratic societies (in the
US this is done by the
First Amendment), it does not include all types of speech. In fact spoken or written "true threat" speech/text is criminalized because of "intent to harm or intimidate", that also applies for online or any type of network related threats in written text or speech.
[20] The US
Supreme Court definition of "true threat" is "statements where the speaker means to communicate a serious expression of an intent to commit an act of unlawful violence to a particular individual or group".
[20]Drug trafficking[edit]
Documented cases[edit]
One of the highest profiled banking computer crime occurred during a course of three years beginning in 1970. The chief teller at the Park Avenue branch of New York's
Union Dime Savings Bank embezzled over $1.5 million from hundreds of accounts.
[21]A hacking group called MOD (Masters of Deception), allegedly stole passwords and technical data from
Pacific Bell,
Nynex, and other telephone companies as well as several big credit agencies and two major universities. The damage caused was extensive, one company,
Southwestern Bell suffered losses of $370,000 alone.
[21]In 1983, a nineteen-year-old UCLA student used his PC to break into a Defense Department international communications system.
[21]Between 1995 and 1998 the
Newscorp satellite pay to view encrypted
SKY-TV service was hacked several times during an ongoing technological
arms race between a pan-European hacking group and Newscorp. The original motivation of the hackers was to watch Star Trek re-runs in Germany; which was something which Newscorp did not have the copyright to allow.
[22]On 26 March 1999, the
Melissa worm infected a document on a victim's computer, then automatically sent that document and a copy of the virus spread via e-mail to other people.
In February 2000, an individual going by the alias of
MafiaBoy began a series
denial-of-service attacks against high-profile websites, including
Yahoo!,
Amazon.com,
Dell, Inc.,
E*TRADE,
eBay, and
CNN. About fifty computers at
Stanford University, and also computers at the University of California at Santa Barbara, were amongst the
zombie computerssending pings in
DDoS attacks. On 3 August 2000, Canadian federal prosecutors charged
MafiaBoy with 54 counts of illegal access to computers, plus a total of ten counts of mischief to data for his attacks.
The
Russian Business Network (RBN) was registered as an internet site in 2006. Initially, much of its activity was legitimate. But apparently the founders soon discovered that it was more profitable to host illegitimate activities and started hiring its services to criminals. The RBN has been described by
VeriSign as "the baddest of the bad".
[23] It offers web hosting services and internet access to all kinds of criminal and objectionable activities, with an individual activities earning up to $150 million in one year. It specialized in and in some cases monopolized
personal identity theft for resale. It is the originator of
MPack and an alleged operator of the now defunct
Storm botnet.
On 2 March 2010, Spanish investigators arrested 3
[clarification needed] in infection of over 13 million computers around the world. The "botnet" of infected computers included PCs inside more than half of the
Fortune 1000 companies and more than 40 major banks, according to investigators.
In August 2010 the international investigation
Operation Delego, operating under the aegis of the
Department of Homeland Security, shut down the international
pedophile ring Dreamboard. The website had approximately 600 members, and may have distributed up to 123 terabytes of child pornography (roughly equivalent to 16,000 DVDs). To date this is the single largest U.S. prosecution of an international child pornography ring; 52 arrests were made worldwide.
[24]On March 1, 2011 at
Lassiter High School, two students were accused of impersonation of a staff member via cybercrime, but both claimed they were uninvolved. The offense was made a felony in the Cobb County School District two months after the impersonation had happened. Shortly afterwards, the head of the LHS School Board said "The teacher just wouldn't do this at all". The case ended on May 9, and no evidence was found.
In June 2012
LinkedIn and
eHarmony were attacked, compromising 65 million
password hashes. 30,000 passwords were cracked and 1.5 million EHarmony passwords were posted online.
[25]In January 2012
Zappos.com experienced a security breach after as many as 24 million customers' credit card numbers, personal information, billing and shipping addresses had been compromised.

Diffusion of cybercrime[edit]
The broad diffusion of cybercriminal activities is an issue in computer crimes detection and prosecution. According to Jean-Loup Richet (Research Fellow at ESSEC ISIS), technical expertise and accessibility no longer act as barriers to entry into cybercrime.
[30] Indeed, hacking is much less complex than it was a few years ago, as hacking communities have greatly diffused their knowledge through the Internet. Blogs and communities have hugely contributed to information sharing: beginners could benefit from older hackers' knowledge and advice. Furthermore, Hacking is cheaper than ever: before the
cloud computing era, in order to spam or scam one needed a dedicated server, skills in server management, network configuration and maintenance, knowledge of Internet service provider standards, etc. By comparison, a mail
software-as-a-service is a scalable, inexpensive, bulk, and transactional e-mail-sending service for marketing purposes and could be easily set up for
spam.
[31] Jean-Loup Richet explains that cloud computing could be helpful for a cybercriminal as a way to leverage his attack – brute-forcing a password, improve the reach of a
botnet, or facilitating a spamming campaign.
[32]Investigation[edit]
Legislation[edit]
Due to easily exploitable laws, cybercriminals use developing countries in order to evade detection and prosecution from law enforcement. In developing countries, such as the Philippines, laws against cybercrime are weak or sometimes nonexistent. These weak laws allow cybercriminals to strike from international borders and remain undetected. Even when identified, these criminals avoid being punished or extradited to a country, such as the United States, that has developed laws that allow for prosecution. While this proves difficult in some cases, agencies, such as the FBI, have used deception and subterfuge to catch criminals. For example, two Russian hackers had been evading the FBI for some time. The FBI set up a fake computing company based in Seattle, Washington. They proceeded to lure the two Russian men into the United States by offering them work with this company. Upon completion of the interview, the suspects were arrested outside of the building. Clever tricks like this are sometimes a necessary part of catching cybercriminals when weak legislation makes it impossible otherwise.
[33]President Barack Obama released in an executive order in April 2015 to combat cybercrime. The executive order allows the United States to freeze assets of convicted cybercriminals and block their economic activity within the United States. This is some of the first solid legislation that combats cybercrime in this way.
[34]Penalties[edit]
Penalties for computer related crimes in New York State can range from a fine and a short period of jail time for a Class A misdemeanor such as unauthorized use of a computer up to computer tampering in the first degree which is a Class C felony and can carry 3 to 15 years in prison.
[citation needed]However, some
hackers have been hired as
information security experts by private companies due to their inside knowledge of computer crime, a phenomenon which theoretically could create
perverse incentives. A possible counter to this is for courts to ban convicted hackers from using the Internet or computers, even after they have been released from prison – though as computers and the Internet become more and more central to everyday life, this type of punishment may be viewed as more and more harsh and draconian. However, nuanced approaches have been developed that manage cyberoffender behavior without resorting to total computer and/or Internet bans.
[36] These approaches involve restricting individuals to specific devices which are subject to computer monitoring and/or computer searches by probation and/or parole officers.
[37]Awareness[edit]
As technology advances and more people rely on the internet to store sensitive information such as banking or credit card information, criminals are going to attempt to steal that information. Cyber-crime is not only becoming more of a threat to people in The U.S. but also people across the world. Raising awareness about how information is being protected and the tactics criminals use to steal that information is important in today's world. According to the FBI's Internet Crime Complaint Center in 2014 there were 269,422 complaints filed. With all the claims combined there was a reported total loss of $800,492,073. But yet cyber-crime doesn't seem to be on the average person's radar. There are 1.5 million cyber-attacks annually, that means that there are over 4,000 attacks a day, 170 attacks every hour, or nearly three attacks every minute. Anybody who uses the internet for any reason can be a victim, which is why it is important to be aware of how one is being protected while online.
