Quote:Turla, also known as Venomous Bear, Waterbug, and Uroboros, may be best known for what was at the time an “ultra complex” snake rootkit focused on NATO-related targets, but their malware set and activity is much broader. Our current focus is on more recent and upcoming activity from this APT, which brings an interesting mix of old code, new code, and new speculations as to where they will strike next and what they will shed.

Much of our 2018 research focused on Turla’s KopiLuwak javascript backdoor, new variants of the Carbon framework and meterpreter delivery techniques. Also interesting was Mosquito’s changing delivery techniques, customized PoshSec-Mod open-source powershell use, and borrowed injector code. We tied some of this activity together with infrastructure and data points from WhiteBear and Mosquito infrastructure and activity in 2017 and 2018.

For a first, our KopiLuwak research identified targets and delivery techniques, bringing more accuracy and reliability to the discussion. Also interesting is a review of Turla scripting artefacts leading to newer efforts like KopiLuwak, tracing from older scripting in development efforts in WhiteAtlas and WhiteBear. And, we find 2018 KopiLuwak delivery techniques that unexpectedly matched Zebrocy spearphishing techniques for a first time as well.
