MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a high-severity heuristic firing indicating it links to a game hack generator, identified as a common lure. The embedded URL, https://netcdn.xyz/app/406889139/spin-free-coin-master-game-hack, is the primary indicator of this malicious redirection. While no scripts were explicitly extracted, the nature of the lure suggests potential for further malicious activity upon redirection.

Machine Learning

  • Nyx PDF Classifier malicious score 0.8565

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.
