#2. What are some characteristics of common computer criminals, including their objective?

        ans : Convicted computer criminals are people who are caught and convicted of computer crimes such as breaking into computers or computer networks.^[1] Computer crime can be broadly defined as criminal activity involving information technology infrastructure, including illegal access (unauthorized access), illegal interception (by technical means of non-public transmissions of computer data to, from or within a computer system), data interference (unauthorized damaging, deletion, deterioration, alteration or suppression of computer data), systems interference (interfering with the functioning of a computer system by inputting, transmitting, damaging, deleting, deteriorating, altering or suppressing computer data), misuse of devices, forgery (or identity theft) and electronic fraud.^[2]

In the infancy of the hacker subculture and the computer underground,^[3] criminal convictions were rare because there was an informal code of ethics that was followed by white hat hackers.^[4] Proponents of hacking claim to be motivated by artistic and political ends, but are often unconcerned about the use of criminal means to achieve them.^[5] White hat hackers break past computer security for non-malicious reasons and do no damage, akin to breaking into a house and looking around.^[6] They enjoy learning and working with computer systems, and by this experience gain a deeper understanding of electronic security.^[6] As the computer industry matured, individuals with malicious intentions (black hats) would emerge to exploit computer systems for their own personal profit.^[6]

Convictions of computer crimes, or hacking, began as early as 1983 with the case of The 414s from the 414 area code in Milwaukee. In that case, six teenagers broke into a number of high-profile computer systems, including Los Alamos National Laboratory, Sloan-Kettering Cancer Center and Security Pacific Bank. On May 1, 1983, one of the 414s, Gerald Wondra, was sentenced to two years of probation.^[7] As of 2009, the longest prison term for computer crimes—nearly five years—was handed down to Jeanson James Ancheta, who created hundreds of zombie computers to do his bidding via giant bot networks or botnets.^[8] He then sold the botnets to the highest bidder who in turn used them for Denial-of-service (DoS) attacks.^[update]
