New IM worms hit MSN Messenger
CRN.com | at | by Mike
New worms spreading through MSN Messenger -- and its bundled-with-Windows Windows Messenger version -- via links to a malicious site are infecting users and leaving their PCs open to hacker hijack, security vendors reported Monday.
The new worms, tagged as Kelvir.a and Kelvir.b, appeared over the weekend and on Monday, respectively, anti-virus vendors said. Both use the same mechanism to attract users and infect Windows-based PCs: they include a link in the instant message. That link, in turn, downloads a malicious file -- the actual worm, a variant of the long-running Spybot -- which opens a backdoor to the compromised machine.
