VERY IMPORTANT

Turla is a notorious espionage group, and has been active for at least ten years. It came to light in 2008, when Turla breached the US Department of Defense [1]. Since then, there have been numerous security incidents involving Turla targeting several governments and sensitive businesses such as the defense industry [2]. Our January 2018 white paper [3] was the first public analysis of a Turla campaign called Mosquito. We have also published indicators of compromise [4]. Since then, the campaign has remained very active and attackers have been busy changing their tactics to remain as stealthy as possible.
