UNC5266  (Back to overview)


Mandiant created UNC5266 to track post-disclosure exploitation leading to deployment of Bishop Fox's SLIVER implant framework, a WARPWIRE variant, and a new malware family that Mandiant has named TERRIBLETEA. At this time, based on observed infrastructure usage similarities, Mandiant suspects with moderate confidence that UNC5266 overlaps in part with UNC3569, a China-nexus espionage actor that has been observed exploiting vulnerabilities in Aspera Faspex, Microsoft Exchange, and Oracle Web Applications Desktop Integrator, among others, to gain initial access to target environments.
