Venomous Bear
Venomous Bear, also referred to as Turla, Snake, Uroboros, and other aliases, is a sophisticated cyber-espionage group attributed to Russia's Federal Security Service (FSB). Active since at least 2004, this advanced persistent threat (APT) group specializes in gathering intelligence through state-of-the-art malware, stealthy campaigns, and strategic targeting methods.

Tactics
The primary goal of Venomous Bear is espionage, with a focus on collecting intelligence rather than destructive or financially motivated activities. Their campaigns often target diplomatic relations, defense strategies, and foreign policy intelligence to serve state objectives.
Techniques
Venomous Bear employs spear-phishing, watering hole attacks, and supply chain compromises to gain initial access. They use advanced, cross-platform malware and employ hijacked satellite communication infrastructure for command and control (C2), obscuring attribution while maintaining access.
Procedures
A notable example of their method is their deployment of the Lunar toolset—comprising LunarLoader, LunarWeb, and LunarMail—targeting foreign ministries and diplomatic entities. They also leverage tailored malware, such as ApolloShadow, to intercept encrypted traffic via rogue root certificates.
