Cisco Coverage for 'Regin' Campaign
Summary: Cisco Talos reported that the Regin malware, publicly disclosed in the prior two days, targets organizations in the Financial, Government, and Telecommunications verticals as well as research institutions in Education. Regin uses a multi-stage architecture in which each stage is decrypted and executed in sequence, then contacts a command-and-control server to exfiltrate user data such as keystrokes and screenshots.
What you should know: Talos released Snort rules 32621-32624, a ClamAV signature named Win.Trojan.Regin, and blocklisted four command-and-control IP addresses, but its ClamAV and AMP coverage for this malware dates only to early 2013 - so any detection gap before that point sits on the defender's side of the ledger.
