Malware Config

Signatures

    Adversaries may achieve persistence by adding a Registry key to the Active Setup of the local machine.

  • Manipulates Digital Signatures 1 TTPs 60 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 1 IoCs

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

  • Event Triggered Execution: Component Object Model Hijacking 1 TTPs
