At least three variants of a new massmailer / network worm combo is on the loose. We currently detect it as W32/Lebreat.A@mm.This virus claims to be "Breatle AntiVirus v1.0", and it spreads over both email and network vulnerabilities such as RPC and LSASS.Apparently it also tries to launch a DDoS attack against www.symantec.com. With no visible effects so far.The worm also contains an anti-Symantec message: easy to talk but hard to work :) what about working in symantec? :P it is not only a mass mail worm it is also a lsass worm :)The worm sends variable emails, with messages such as: Your credit card was charged for $500 USD.
