According to [Zscaler ThreatLabZ][2], the Zeus Banking Trojan logs on to the social network via compromised accounts and stolen credentials, proceeding to post photos which prompt users to download them. Users then receive a screen saver, complete with the Zeus Banking Trojan and other malicious files.
Zscaler ThreatLabZ Senior Security Researcher Mike Geide added:
Zeus is a Trojan designed to steal banking credentials. The newer variants of Zeus include P2P functionality making the botnet much more resistant to take-down.
Facebook continues to be a popular medium for malware attacks, given the easy propagation mechanism built into social networking. By definition, social networking is social. Facebook is built to easily allow people to share pictures, videos, and other content, and people trust what they are receiving from their friends. Malware, such as this recent example, can take advantage of the sharing mechanisms and users' trust of their friends within social networking.
Readers: Have you been victimized by the Zeus Banking Trojan or other malware?
