MITRE ATT&CK

T1566.001 Spearphishing Attachment

The primary malicious URL identified is http://netcdn.co/app/406889139/free-coin-master-links-game-hack. While no scripts were explicitly extracted, the PDF structure and embedded links suggest a social engineering tactic to redirect users to potentially malicious websites, likely for credential harvesting or malware distribution.

Heuristics 4

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.
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON

Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow

Embedded URL info EMBEDDED_URL
