Chuck Norris Botnet: Router Virus

Sunday, February 21st, 2010 | Hardware, Internet, TECHNOLOGY with 1 Comment

The new virus Chuck Norris got its name through an Italian programmer’s comment: “in nome di Chuck Norris,” meaning “in the name of Chuck Norris.”  Norris is a well known U.S. Martial arts actor.  The malware, discovered by Czech researchers, spreads through routers and DSL modems, according to Jan Vykopal, the head of the network security department of Masaryk University’s Institute of Computer Science in Brno, Czech Republic.

The unusual thing with this virus is that it infects DSL modems and routers rather than the PC.  The botnet installs itself on routers and modems by randomly getting the default administrative passwords remotely. D-Link Systems devices were identified as the main vulnerable device.

Chuck Norris, like Psybot, can infect satellite TV receivers and an MIPS-based device using Linux operating system if its administration interface has a weak username and password. Infected machines can be used to attack other systems on the Internet, through a distributed denial of service attacks. Chuck Norris botnet lives in the router’s RAM, it can be removed with a resetting the device.
