  • Ingest the provided SHA-256 and MD5 file hashes into endpoint detection and response (EDR) blocklists.
  • Perform retrospective hunting across all managed macOS endpoints for the presence of these file hashes.
  • Ensure file integrity monitoring (FIM) is active on critical system paths to detect unauthorized executable deployment.
