MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF document contains a link disguised as a 'game hack' generator, which is a common social engineering tactic. The embedded URL leads to a suspicious domain, likely serving a malicious payload or redirecting to a phishing site. No scripts were extracted, but the PDF structure and embedded URI heuristic indicate a malicious intent to lure users to a compromised resource.

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.
