MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains a link disguised as a 'free generator / game hack' for Roblox, which is a common lure for phishing or malware distribution. The ML classifier strongly indicated maliciousness. The embedded URL likely leads to a malicious site designed to exploit user interest in free in-game items.

  • Nyx PDF Classifier malicious score 0.9907

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.
