MITRE ATT&CK

T1566.001 Spearphishing Attachment T1059.007 JavaScript

This PDF document contains multiple links that redirect to malicious infrastructure, specifically promoting 'game hacks' and 'generators' for popular games. The primary lure appears to be a 'Coin Master Connection Lost Hack' redirecting to http://netcdn.tw/app/406889139/coin-master-connection-lost-hack-game-hack. The presence of embedded URLs and the ML classifier's high confidence score indicate a malicious intent to lure users to potentially harmful sites. No scripts were extracted, but the document's structure and embedded links strongly suggest a phishing or scam attempt.

Heuristics 4

PDF links to a 'free generator / game hack' redirector critical 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. CRITICAL on its own: the /app/<id>/<slug>-game-hack path shape is unambiguous scam infra, and the host rotates so a host-list match can't be relied on.
PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK

PDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
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

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.
