Trojan BackDoor.Flashback

Trojan BackDoor.Flashback, commonly referred to as the Flashback Trojan, is a Trojan horse affecting personal computer systems running Mac OS X. The first variant of Flashback was discovered by antivirus company Intego in September 2011.

Infection

According to the Russian antivirus company Dr. Web, a modified version of the "BackDoor.Flashback.39" variant of the Flashback Trojan has infected over 600,000 Mac computers, forming a botnet that includes 274 bots located in Cupertino, California. The findings were confirmed one day later by another computer security firm, Kaspersky Lab. This variant of the malware was first detected in April 2012 by Finland-based computer security firm F-Secure. Dr. Web estimated that in early April 2012, 56.6% of infected computers were located within the United States, 19.8% in Canada, 12.8% in the United Kingdom and 6.1% in Australia.

Details

The Trojan targets a Java vulnerability on Mac OS X. The system is infected after the user is redirected to a compromised bogus site, where JavaScript code causes an applet containing an exploit to load. An executable file is saved on the local machine, which is used to download and run malicious code from a remote location. The malware also switches between various servers for optimised load balancing. Each bot is given a unique ID that is sent to the control server. The trojan, however, will only infect the user visiting the infected web page, meaning other users on the computer are not infected unless their user accounts have been infected separately.
