MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a high-risk heuristic indicating it links to a game hack redirector, specifically targeting Coin Master. The document body and extracted URLs reinforce this lure, directing users to potentially malicious websites. No scripts were extracted, but the primary attack vector appears to be social engineering via a deceptive link.

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.
