Turla, a hacking group that has been active for over ten years and one of the largest known state-sponsored cyberespionage groups, is showing a shift in its behaviour from using its own creations to leveraging the open source exploitation framework Metasploit before dropping the custom Mosquito backdoor. While this is not the first time Turla is using generic tools, researchers at ESET say that this is the first time the group has used Metasploit, which is an open-source penetration testing project, as a first stage backdoor. "In the past, we have seen the group using open-source password dumpers such as Mimikatz," ESET Research said in a blog post. "However, to our knowledge, this is the first time Turla has used Metasploit as a first stage backdoor, instead of relying on one of its own tools such as Skipper." The typical targets of the attacks remain to be embassies and consulates in Eastern Europe and the group is still using a fake Flash installer to install both the Turla backdoor and the legitimate Adobe Flash Player.
