MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a prominent link disguised as a 'free generator / game hack' lure, which is a common social engineering tactic. The heuristic 'PDF_GAME_HACK_REDIRECT_LURE' directly supports this. The document body and extracted URLs reinforce the theme of obtaining free in-game currency or cheats, further indicating a scam or phishing attempt. No scripts were extracted, but the primary attack vector appears to be directing the user to a malicious URL.

Heuristics 3

  • PDF links to a 'free generator / game hack' redirector high PDF_GAME_HACK_REDIRECT_LURE
    PDF's clickable action targets a redirector of the form /app/<id>/<slug>-game-hack — the landing-page shape of a large SEO 'free spins / generator / game hack' lure family that funnels victims through rotating disposable hosts to a malware/scam payload. The multi-link variants also trip ML/link-farm rules; this catches the single-link variants that otherwise score clean.
  • 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.
