This news is a slap on the face of Microsoft, who tried offering $250 million for a tip off on the creators of Conficker worm. Not only that the creators have managed to remain anonymous, they have now up their ante against security vendors who are working to stop the worm spread.

The latest version of Conficker worm, named Conficker.C, shuts down security services, blocks computers from connecting to security Web sites, and downloads a Trojan. It also is programmed to begin connecting to 50,000 different domains on April 1 to receive updated copies or other malware, as opposed to connecting to 250 domains a day as previous versions are doing. Now, stop thinking if this is an April fool prank.
