The new worm poses as an invitation to a Christmas-themed Web site.
A new worm posing as a come-on to a Santa Claus site is traveling across all the major instant messaging networks, a security firm warned Tuesday, and when recipients visit the bogus site, they're infected with a file hidden from sight by a rootkit.
IMlogic said that the worm, dubbed "M.GiftCom.All," is circulating on the MSN, AOL, ICQ, and Yahoo instant messaging services, is a "Medium" threat, a relatively rare classification for the Waltham, Mass.-based company. Most IM worms and Trojans listed on its Threat Center receive only a "Low" classification.
Like virtually all IM worms, M.GiftCom.All includes a URL in messages it spams out to contacts hijacked from previously-infected PCs. When users naively visit that site -- which is billed as a harmless Santa site -- a file is automatically downloaded to their computers.
The file, usually named "gift.com," includes rootkit elements that cloaks it from security software. In addition, the downloaded executable tries to disable a number of anti-virus programs, adds a keylogger to the system to capture confidential information, and then spreads to others by snatching names from the user's IM client contact list.
