FIN7 continued to leverage PowerShell throughout their intrusions, including in a new backdoor called POWERPLANT, which FIN7 has continually developed over the last two years.
Mandiant also identified new versions of the BIRDWATCH downloader being developed, which are tracked as CROWVIEW and FOWLGAZE.
FIN7’s initial access techniques have diversified to include software supply chain compromise and the use of stolen credentials, in addition to their traditional phishing techniques.
Mandiant also observed FIN7 use POWERPLANT as their first stage malware instead of LOADOUT and/or GRIFFON in newer intrusions.
Data theft extortion or ransomware deployment following FIN7-attributed activity at multiple organizations, as well as technical overlaps, suggests that FIN7 actors have been associated with various ransomware operations over time.
Mandiant is also tracking multiple, notable campaigns as separate UNC groups that Mandiant suspects are FIN7, including a “BadUSB” campaign leading to DICELOADER, and multiple phishing campaigns leveraging cloud marketing platforms leading to BIRDWATCH.
