CYBERCRIME in U.S.A.: news - DDOS attacks and Zombie

United States Attorney McGregor W. Scott announced today that XX, 21 was sentenced to two years in federal prison. XX was also ordered to pay over $69,000 in restitution. Online, XX was known as Silenz, Silenz420, sZ, GregK, and Gregk707. He had pleaded guilty to two counts of transmitting code to cause damage to a protected computer on June 10, 2008.
This case is the product of an extensive investigation by the FBI, whose agents analyzed Internet logs, executed search warrants, performed forensic analysis of XX’s computers, and took XX’s confession.
According to Assistant United States Attorney XX admitted to using a “botnet” to conduct distributed denial of service attacks (DDOS attacks) against two different business Web sites: Killanet and Castlecops. A botnet is a network of malware-infected, zombie computers (bots) that can be used to conduct DDOS attacks, send spam, and commit fraud over the Internet. Bots are also used to infect other computers and thus propagate the botnet. The owners of the infected computers do not know that their computers have been infected with “botware,” but their computers can nonetheless be secretly directed by the “bot herder,” the person in control of the botnet. In a DDOS attack, a bot herder directs the bots to flood a victim computer with information and thereby disable the target computer.
XX admitted to controlling about 7,000 bots and using them to DDOS attack Killanet and Castlecops. Killanet is an interactive forum where members could share advice on graphic design, web design, photography, and gaming and was DDOS attacked in 2004, 2005, and 2006. Castlecops is an Internet security community specializing in anti-phishing, malware analysis, and combatting spam and was DDOS attacked in 2007.
On October 1, 2007, FBI agents went to XX’s residence to arrest him. After agents knocked on the front door, XX exited the back door, hid a laptop computer in the backyard, and then returned to answer the front door. Pursuant to a search warrant, the laptop was seized and searched. It contained, among other things, botnet software and references to XX’s various Internet monikers.
