United States Cyber Command has blamed Russian hacking groups for two major malware strains to warn organizations about cyberattacks.

In late October, Cyber Command, part of the Department of Defense, attributed the Zebrocy malware to the APT28 hacking group and the ComRAT malware to the Turla hacking group. While other cybersecurity experts have previously attributed the two malware families to Russian hacking groups, the Cyber Command warnings appear to be an effort to help organizations defend against the malware.
