Analysis Summary
The APT group Turla is known by many names including Krypton, MAKERSMARK, Snake, Uroburosk, Venomous Bear, Waterbug and WhiteBear, and is tracked by researchers. Turla is primarily known for its espionage activities. In 2017, ESET researchers observed a new version of one of Turla’s tools named ComRAT. The new version featured a new C++ code base and more complexity than prior versions. It is known to have been in use as recently as January 2020 and is believed to be used exclusively by Turla. ComRAT v4’s primary use is locating documents which are then compressed and exfiltrated to a public cloud storage service. Three government entities, two foreign affairs ministries, and a national parliament are known to have been targeted with ComRAT v4. It is installed on systems where the group already have a foothold. Two C&C communications channels are used by ComRAT v4, HTTP (the same as in ComRAT v3), and email, which uses Gmail to receive commands.
