Technical similarities (the same functionality and command-and-control servers) between this new Linux virus and Windows DLL files point to the same creator. Vermilion Strike uses the same configuration format as the official Windows beacon and can communicate with all Cobalt Strike servers. The Cobalt Strike ELF binary found by Intezer researchers, who first saw the beacon re-implementation in August and called it Vermilion Strike, is currently undetectable by anti-malware solutions.

The threat actors may now acquire permanence and remote command execution on both Windows and Linux devices by using these beacons. Researchers describe how threat actors have taken it upon themselves to make their Linux beacons compatible with Cobalt Strike in a new study from security firm Intezer.

In time, threat actors obtained and disseminated cracked versions of Cobalt Strike, making it one of the most prevalent tools used in assaults involving data theft and ransomware.Ĭobalt Strike has always had a flaw: it only works with Windows devices and does not support Linux beacons.

Security researchers discovered an unauthorized Cobalt Strike Beacon Linux version used in attacks against companies all across the world.Ĭobalt Strike is a legitimate penetration testing tool created as an attack framework for red teams (security professionals who act as attackers against their own organization’s infrastructure in an attempt to find security flaws and vulnerabilities.)Ĭobalt Strike is also used by threat actors for post-exploitation activities after distributing so-called beacons, which allow continuous remote access to compromised devices (often exploited in ransomware campaigns).Īttackers can afterward utilize beacons to connect directly to compromised systems and gather data or distribute further malware payloads.
