  • Identifies VirtualBox via ACPI registry values (likely anti-VM) 2 TTPs 1 IoCs
  • Checks BIOS information in registry 2 TTPs 2 IoCs

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

  • Identifies Wine through registry keys 2 TTPs 1 IoCs

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

  • Checks whether UAC is enabled 1 TTPs 1 IoCs
  • Writes to the Master Boot Record (MBR) 1 TTPs 1 IoCs

    Bootkits write to the MBR to gain persistence at a level below the operating system.
