Trusteer detects rapid spread of new polymorphic Zeus trojan
21 April 2010
Trusteer says it has detected a completely new version of the Zeus password stealing trojan that has been designed to steal online banking credentials.
The internet authentication, encryption and security specialist says that its Rapport browser security service, which is used by a number of major banks, has detected the Zeus trojan variant on around one in 3000 PCs monitored by the Rapport servers.
According to Trusteer, this is an unprecedented rate of distribution for new financial malware code.
The firm reports that Version 1.4 – also known as version 2 – of Zeus targets Firefox browsers and uses advanced polymorphic techniques to avoid anti-virus detection.
