Cisco Talos is aware of the public discourse surrounding the malware family dubbed “The Equation Family”. As of February 17th the following rules (33543 - 33546 MALWARE-CNC Win.Trojan.Equation) were released to detect the Equation Family traffic. These rules may be found in the Cisco FireSIGHT Management Console (Defense Center), or in the Subscriber Ruleset on Snort.org. Talos security researchers have also added the associated IPs, Domains, URLs, and hashes to all Cisco security devices to provide immediate protection across the network. Talos will continue to monitor public information as well as continue to independently research to provide coverage to this malware family.

Advanced Malware Protection (AMP) is ideally suited to prevent the execution of the malware used by these threat actors.

CWS or WSA web scanning prevents access to malicious websites and detects malware used in these attacks.

The Network Security protection of IPS and NGFW have up-to-date signatures to detect malicious network activity by threat actors.

While email has not been observed as an attack vector, ESA is capable of blocking the malware used in this campaign.
