In June CrowdStrike identified and attributed a series of targeted intrusions at the Democratic National Committee (DNC), and other political organizations that utilized a well known implant commonly called X-Agent. X-Agent is a cross platform remote access toolkit, variants have been identified for various Windows operating systems, Apple’s iOS, and likely the MacOS. Also known as Sofacy, X-Agent has been tracked by the security community for almost a decade, CrowdStrike associates the use of X-Agent with an actor we call FANCY BEAR. This actor to date is the exclusive operator of the malware, and has continuously developed the platform for ongoing operations which CrowdStrike assesses is likely tied to Russian Military Intelligence (GRU). The source code to this malware has not been observed in the public domain and appears to have been developed uniquely by FANCY BEAR.
