MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains multiple links to external websites, masquerading as game hacks or generators. The primary lure URL is https://netcdn.online/app/431946152/roblox-ftw-game-hack, which likely leads to a malicious download or phishing page. While no scripts were explicitly extracted, the PDF structure and embedded links suggest a social engineering tactic to redirect users to potentially harmful content.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9990

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.
