Banking malware hosted on Amazon's cloud servers

Posted by   Virus Bulletin on   Jun 6, 2011

Trojan targets mostly Brazilian banks.

Researchers have discovered malware hosted on Amazon Web Services that steals victims' bank account data.

Acting as a rootkit, the malware attempts to deactivate at least four different anti-virus programs as well as a special security application used by many Brazilian banks to protect their customers' online banking accounts.

The malware also steals Windows Live credentials and information on the hardware used by the victim. Many Latin American banks use this latter kind of information to detect login attempts from unknown sources and thus this information will help the cybercriminals to appear legitimate.

Most worrying of all is the fact that the malware is hosted on Amazon Web Services, Amazon's popular cloud service. By using a well-known server with a good reputation, it is less likely that the malware will be blocked by web filters. Equally worrying is that at the time of writing - more than 48 hours after researchers from Kaspersky warned Amazon about the trojan - the malware is still online.

Kaspersky's Fabio Assolini will give a presentation on Brazilian cybercriminals at VB2011. Registration for the conference (which takes place 5-7 October in Barcelona, Spain) is now open; early bird discounts apply until 15 June.
