Turla (once known as Uroburos) is a highly sophisticated advanced persistent threat (APT) campaign that has long since been suspected to have ties to the Russian government, dating back to at least 2008 and likely lasting till the world ends.
This cross-platform malware family has been seen on both Windows and Linux operating systems. It uses a wide variety of crazy tactics and strategies to infiltrate embassies, military bases, and critical infrastructure across Europe and in the Americas.
This week, researchers at ESET made an interesting discovery in the advancement of this trojan’s circus of antics that has now roped in pop idol, Britney Spears.
Once abusing Google Analytics and various other watering hole techniques, the authors of Turla have gone out of their way to implement security methods that have overprotected its ability to exfiltrate data and communicate with its control servers. Not satisfied with traditional methods of establishing back channel communication with its command and control (C2) servers, the authors decided to go with something a little stronger.
Using obscure tactics, not unlike Britney Spear’s current music career choices, the authors looked to Spears’ Instagram account to break the ice and had the APT decode the author’s C2 server address.

The authors of this malware managed to develop a scheme that filtered over 6500 comments on Britney’s pictures and filtered it down to a single comment:
