MITRE ATT&CK
T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The ML classifier strongly flagged this PDF as malicious. The document body and embedded URLs suggest a lure for game-related cheats or hacks, which is a common social engineering tactic. The presence of a "download button" heuristic further supports the intent to trick the user into downloading a payload.

  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
