MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a high-severity heuristic indicating it links to a game hack redirector, specifically targeting PUBG players. The embedded URL, http://netcdn.tw/app/1330123889/what-pubg-uc-code-game-hack, is the primary IOC. While no scripts were extracted, the PDF structure and lure suggest a phishing or scam attempt, likely initiating a download or redirect to a malicious site.

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.
