Introduction
- Quarantine the file and compute cryptographic hashes.
- Compare hashes with known-good vendor values; if unknown, search threat intelligence sources for matches.
- Mount the image in a sandbox to inventory files and look for anomalous executables or scripts.
- Check paste-in logs and deployment systems for any instances where the image was used.
- Rotate credentials potentially exposed during deployments and restore systems from known-good snapshots if compromise is suspected.
- Possible interpretations:
- CRC checks on FVs.
- Encrypted DXE drivers (e.g., Intel Boot Guard verified but not encrypted — but OEMs add own crypto).
- Anti-debug tricks inside PEI phase.
