Evil Santa Likes To IM People
With the holidays upon us, the name of Santa Claus is being used for evil rather than good by worm developers, who have targeted major instant-messaging systems with a holiday-themed virus.
The IM.GiftCom.All worm has made an appearance on several messaging networks, including America Online, Microsoft MSN, and Yahoo.
The worm attempts to dupe you into believing that a friend has sent you a link to a harmless file. If you click on the file, you see an image of Santa. While viewing it, the worm attempts to install a rootkit on your system. - Yahoo News
