T1566.001 Spearphishing Attachment
T1203 Exploitation for Client Execution
The PDF document contains lures for game hacks and free spins, directing users to external URLs such as http://netcdn.tw/app/406889139/coin-master-free-spins-link-download-game-hack. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded links suggests an attempt to redirect users to potentially malicious sites or phishing pages. While no scripts were explicitly extracted, the PDF structure and embedded links are indicative of a social engineering attack.

Heuristics 4
-
PDF links to a 'free generator / game hack' redirector high PDF_GAME_HACK_REDIRECT_LUREPDF'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_BUTTONDocument 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_URIPDF contains an external URL action
-
Embedded URL info EMBEDDED_URLOne 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.URL http://netcdn.tw/app/406889139/coin-master-free-spins-link-download-game-hack PDF link annotation
