One of the most sophisticated and dangerous malware applications in the history of computers is set to unleash its fury on April 1, 2009. Conficker C is nasty enough to warrant a $250,000 bounty from Microsoft for any information leading to the identification and prosecution of the worm’s authors.
From the limited research I’ve been able to do, it appears that, on April 1, any computer infected with Conficker C will automatically and immediately come under the control of the worm’s controllers. Little is known as of yet what those individuals intend to do with that control, but the possibilities are nearly endless. The implications could range from simply popping up annoying adware windows to reading your entire computer history (passwords, bank information, etc.) to completely wiping your hard drive.
In my research, I did find that this worm presents itself as a dynamic link library (DLL), which is strictly a Windows entity. Therefore, at this time, the worm is not a threat to Linux or Macintosh computers.
