Network of computer security researchers found that Conficker virus has successfully infected approximately 7 million computers worldwide in just over one year. Quoted from Computer World, Saturday (31/10/2009), researchers from the Shadow Server Foundation says they had managed to track down millions of computers IP around the world that infected by Conficker.

Tracking is successfully done by first tracking algorithm used by the virus and then they installed 'sinkhole' servers into the Internet domain name that visited by the program. Conficker deemed to have been sent instructions to the various ways that the creators still can control the PCs. But thanks to the help of 'sinkhole', the researchers could track down the infected machine.

"Although most computer users already know the Conficker virus but along with it the virus also continues to infect. Seven million computers in one year is quite rapid infection of this century," said co-founder Shadow Server Foundation Andre DiMino.

Conficker was first discovered in 2008 and immediately got the attention of internet users, network security experts, and even the mass media. This worm has spread everywhere, especially to China and Brazil. Even software developers have created a dedicated agency to deal with this virus, named Conficker Working Group (CWG).

CWG found that Conficker more often use computers with Microsoft Windows systems as a vehicle. Once infected, users will not be able to download the Microsoft Malicious Software Removal Tool, the software that is expected to treat the infection Conficker.
