MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains multiple links, including one specifically identified as a 'game hack' redirector. The document body, though partially corrupted, also contains references to game hacks and generators. These elements strongly suggest a social engineering tactic to lure users into clicking malicious links, likely for malware distribution or phishing. No scripts were extracted from this sample.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9968

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.
