A virtual blitz of worms is descending on the Internet. In the past four days, six new variants of the mass-mailing Bagle worm and two new variants of the Netsky worm have been spotted in the wild, ITWeb reports.
“It's interesting to note that a variant of Netsky attempts to remove a variant of Bagle, Bagle.C. It looks like a turf war out there, with the bad guys fighting over the infected computers,” says Ken Dunham, director of malicious code at iDefense.
Mikko Hypponen, director of anti-virus research at F-Secure, says the new Bagle variants – Bagle.C, D, E, F, G and H – appear to have been written by the same virus author. The new variants surfaced in quick succession from Friday.
“It seems the writer is waging a virus war,” he notes. “Apparently he has been monitoring closely how quickly the anti-virus vendors have released detections, then made the necessary alterations to avoid detection and released the new versions immediately.”
