    • Darkcomet

      DarkComet is a remote access trojan (RAT) developed by Jean-Pierre Lesueur.

    • Modifies WinLogon for persistence

    • Identifies VirtualBox via ACPI registry values (likely anti-VM)

    • Checks BIOS information in registry

      BIOS information is often read in order to detect sandboxing environments.

    • Identifies Wine through registry keys

      Wine is a compatibility layer capable of running Windows applications, which can be used as sandboxing environment.

    • Uses the VBS compiler for execution

    • Suspicious use of SetThreadContext
