Cyber crime includes everything from electronic cracking to denial of service attacks. It is also used to include traditional crimes in which computers or Research Papers. For that, it is an illegal act in which computers or computer networks are devices, desired goals, and incidental to the crime or places of criminal activities (Rao, 2011). In addition, “This includes anything from downloading illegal music files to stealing millions of dollars from online bank accounts. Cybercrime also includes non-monetary offenses, such as creating and distributing viruses on other computers or posting confidential business information on the Internet” (Ştefan, 2011, p.116). In fact, it is increased in this time. Two years ago there were 250,000 thefts in U.S they wanted steal credit, money in the bank, health insurance, a passport .They want collect a few important number and facts and then use that information to apply for new accounts (Claypoole & Payton, 2008). Cybercrimes can be basically divided into three major categories. There are cybercrimes against people, governments, and properties (Ştefan, 2011). First, Cyber crimes committed against people which consist of activities the posting of obscene and pornographic materials, racist materials or those that instigate to violence, harassment of any nature such as sexual, racial, and religious by the use of computers .For example by mail. In addition, the violation of private life. For example, collection, storage, modification and disclosure of personal data (Ştefan, 2011). Second, Cyber terrorism sort of crimes is used by a person or a group who try to ruin the governments or communities (Ştefan, 2011). This kind of hackers uses the computer to ruin their rivals such as the Pakistanis hacker who were categorized as one of the best hacker in the world against the Indian websites (Dashora, 2011). Third, Cybercrimes against all forms of properties. These crimes include computer when they appoint it for damage destruction of others properties such a computer or system to the other people. In addition, transmission of harmful software to the other people (Ştefan, 2011). Viruses are applications which get into any computer and turn themselves into files on the computer or on the network. Also, it is can be disguised as attachments of funny images, greeting cards, or audio and video files. In addition, it can remove files or lock up a system. (Dashora, 2011). The collapse of cracking computers is sometimes driven by complicated viruses which are made by professional people, such as the virus Melissa which destroyed lots of computers in IT network in the U.S.A and Europe (Ştefan, 2011). In addition, the other kind is Email bombing which means sending lots of emails to victims is known as an email devastating. Therefore, that is why it is essential that you never open any email attachments unless you know who it's from and you are expecting it. (Dashora, 2011). Last kind, a Trojan horse term is used to refer to the ejected programs on the computers and then, they get authorized by turning their forms, also, it is similar to a virus but does not try to copy itself. (Dashora, 2011). In our real world, crimes could horribly increase and spread as quickly as viruses when they attack any computer. Anyhow, every crime has causes behind it, and that happens in the digital world too. In one word, there are many factors and causes could lead to lots of catastrophic cybercrimes. The first reason is that getting money in a short period and with no horrible surprises (Ştefan, 2011). In addition, because it is distinguished by its low cost and the ease with which it can be committed (Dashora, 2011). In fact, “Internet crime outpaced illegal drug trafficking and sales as the major criminal profit maker. Symantec indicated that in 2009 a crime occurred in New York City every three and half minutes, while an identity is stolen online every three seconds” (Claypoole & Payton, 2008). The second reason is that there are no rules to stop hackers around the would because the international cooperation is so expensive and nonexistent on our planet (Ştefan, 2011). For example, illegal trafficking on internet may be trafficking drugs, human being, arms weapons. These forms are going away unchecked because they are passed on under pseudonyms (Dashora, 2011). The third reason is that it is so easy to modern implements that facilitate to their users to do illegal processes (Ştefan, 2011). For instance, the suicide and pornographic sites could be available for the children in traditional ways, such as video tapes and pictures, but these materials on the internet is easier for children to watch more than the old ways (Ong, 2011). Another example is that Form’s of cyber criminals; teenagers and kinds between 6 – 18 years. Instinctively, children like to explore new things, so tyro hackers they try to go into illegal web sites. Another reason is that children like to unique and different from the vest of the children in their groups (Dashora, 2011). On other hand, you can help to protect your own information by understanding how the web sites you visit intend to treat your data. Most commercial have a posted privacy policy that explains how sites owner uses the data you provide. These privacy policies are policed by state attorneys general and by federal agencies. For example, look at one example. Amazon.com is one of the must basic example for the web sites which had a lot of personal information about many people around the would, such as addresses, cards information, and names of people (Claypoole & Payton, 2008). That means digital would need of setting up rules for protecting people is because the mankind are not impenetrable as the notion of law has been said (Dashora, 2011).
