Net watchers wary of Sasser fallout

Friday, 7 May 2004, 1:14 AM EST

One researcher warned on Thursday that the group of online vandals suspected of creating both the Sasser worm and several variations of the Netsky virus could combine the two threats. The resulting blended threat could dodge security inside corporate systems via e-mail messages and then spread quickly once inside those networks.

"Sasser is inhibited by gateways, and adding the e-mail aspect would bypass the gateways," said Jimmy Kuo, a researcher and a McAfee Fellow for security company Network Associates. The technique is "rather obvious," he said, defending the decision to publicize the strategy in an alert. "I don't think I am giving a clue to the virus authors," he said.
