MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a link disguised as a 'free generator / game hack' lure, which is a common social engineering tactic. The ML classifier strongly indicates maliciousness. The embedded URL leads to a site offering free texture packs for Minecraft, further reinforcing the lure. No scripts were extracted, but the primary attack vector is the malicious 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.
