MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs that lure users with promises of game hacks and free currency, specifically targeting Roblox. The primary URL, http://netcdn.tw/app/431946152/roblox-speed-hack-game-hack, is flagged as a high-risk redirector. While no scripts were explicitly extracted, the PDF structure and embedded URIs suggest an attempt to redirect users to potentially malicious sites, likely as part of a phishing or scam campaign.

  • Nyx PDF Classifier malicious score 0.9661

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.
