  • Manipulates Digital Signatures 1 TTPs 61 IoCs

    Attackers can apply techniques such as changing the registry keys of authenticode & Cryptography to make their binary seem validly signed.

  • Checks computer location settings 2 TTPs 3 IoCs

    Looks up country code configured in the registry, likely geofence.

  • Creates a file in the Startup directory 1 TTPs 2 IoCs

    A file was written to a Windows startup folder. Files in these directories are executed automatically when a user logs on or an application initializes.
