Snakefly

Snakefly, also known as FIN11 and TA505, is a threat actor known for its malicious activities primarily aimed at organizations in North America and Europe. The group is financially motivated and has been active since at least early 2019. Snakefly is particularly associated with the deployment of Cl0p ransomware, which was first spotted in 2019. This ransomware is a key tool in their arsenal, frequently used to target and exploit vulnerabilities within organizations for financial gain. In 2023, Snakefly significantly advanced their extortion attacks by exploiting the MOVEit Transfer vulnerability. This new tactic demonstrated an increase in sophistication, as they were able to hit all of their targets simultaneously. By doing so, they left little room for the victims to develop and implement effective defenses against the attack. This strategy highlighted the group's evolving capabilities and underscored the necessity for robust cybersecurity measures among potential target organizations. Dick O'Brien, Principal Intelligence Analyst at Symantec Threat Hunters, has closely followed and reported on Snakefly's activities. His analysis provides valuable insights into the group's tactics, techniques, and procedures (TTPs). Given the continuous evolution and increasing sophistication of Snakefly's operations, it is crucial for organizations to stay informed about the latest developments and to continually review and update their cybersecurity strategies accordingly.
