  • Enumerates physical storage devices 1 TTPs

    Attempts to interact with connected storage/optical drive(s).

  • Executes a command shell one-liner 1 TTPs 18 IoCs

  • Reads the TCP/IP host and domain name from the registry 1 TTPs 12 IoCs

    The configured hostname and DNS domain identify the machine and are commonly collected to profile a host before it reports in.

  • System Location Discovery: System Language Discovery 1 TTPs 8 IoCs

    Attempt gather information about the system language of a victim in order to infer the geographical location of that host.

  • Checks processor information in registry 2 TTPs 8 IoCs

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

  • Interacts with shadow copies 3 TTPs 2 IoCs

    Shadow copies are often targeted by ransomware to inhibit system recovery.

  • Suspicious behavior: EnumeratesProcesses 64 IoCs
  • Suspicious use of AdjustPrivilegeToken 45 IoCs
  • Suspicious use of WriteProcessMemory 28 IoCs
  • Uses Volume Shadow Copy service COM API

    The Volume Shadow Copy service is used to manage backups/snapshots.
