Another day, another virus/worm. Albeit a startlingly polite one, if that's quite the right way to put it.
New MSBlast variant plugs hole | CNET News.com: A variant of MSBlast spread on Monday, but the new worm has an odd twist: It applies a patch for the vulnerability that it and other MSBlast worms use to infect Windows systems. The new worm, dubbed W32.Welchia, W32/Nachi and Worm_MSBlast.D, appears to properly download the patch for both Windows 2000 and Windows XP from Microsoft's Web site. Moreover, the variant will delete itself the first time an infected computer starts up in 2004.
That's terribly peculiar. Nice, I suppose, if you're not Microsoft dealing with all those computers stampeding to your website to download the patch. But still, peculiar.
