MSBlaster Worm Infects Hundreds of Thousands

Posted on August 12, 2003

A worm that takes advantage of the biggest Windows flaw ever has already taken down hundreds of computers running Windows software. The MSBlast worm can shut down computers using Windows 2000, Windows ME and Windows XP. On Saturday, the worm is expected to turn PCs into zombie machines that will launch a denial of service attack against one of Microsoft's websites. A patch is available from Microsoft to protect computers from the worm.

Symantec, which has listed the worm as a Level 4 threat, also has a detailed page providing help to infected users and users looking to patch their computers. Symantec says the worm exploits the Microsoft Windows DCOM RPC Interface Buffer Overrun Vulnerability (BID 8205).
