MITRE ATT&CK

T1566.001 Spearphishing Attachment

The PDF file contains a high-severity heuristic indicating it links to a game hack lure. The document body and extracted URLs confirm this, pointing to sites offering 'free generators' or 'hacks' for games like Coin Master and Roblox. The primary URL, http://netcdn.tw/app/406889139/mangocheats-com-hack-coin-master-cheat-game-hack, is directly associated with this lure, suggesting the PDF is a phishing document designed to redirect users to potentially malicious content.

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
External URI info PDF_URI

PDF contains an external URL action
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
