Associated malware families

4 malware families attributed to this actor across reporting.

FamilyContextEvidenceLast seen
BPFDoorOne of the most recognized tools in its malware arsenal is a Linux backdoor called BPFDoor. "Unlike conventional malware, BPFdoor does not expose listening ports or maintain visible command-and-control channels. Instead, it abuses Berkeley Packet Filter (BPF) functionality to inspect network traffic directly inside the kernel, activating only when it receives a specifically crafted trigger packet."2Mar 26, 2026
CrossC2Upon gaining a successful foothold, Linux-compatible beacon frameworks such as CrossC2 are deployed to facilitate post-exploitation activities.1Mar 26, 2026
SliverAlso dropped are Sliver, TinyShell (a Unix backdoor), keyloggers, and brute-force utilities to facilitate credential harvesting and lateral movement.1Mar 26, 2026
