Malware Writers' Tactics Evolving
A new report by security vendor Commtouch claims attackers are increasingly spreading server side polymorphic malware via email in a bid to circumvent anti virus tools.
According to the report, which focuses on the first four months of 2007, malware writers are using speed, variation and social engineering techniques to mass-distribute their malicious code across the Web.
"The server-side polymorphic distribution method is an evolution of earlier tactics, where malware writers would introduce new variants over a period of weeks or months, to try to bypass anti-virus engines," said Rebecca Herson, senior director of marketing at Commtouch, based in Sunnyvale, Calif., in an interview with eWEEK. "Since the end of 2006, this has become the primary distribution method for e-mail-borne malware." Commtouch: Malware Writers' Tactics Evolving
