The document body also contains the URL 'http://netcdn.tw/app/406889139/coin-master-hack-tool-exe-game-hack', which is likely intended to trick users into downloading malicious content.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9939

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.
