T1566.001 Spearphishing Attachment
The PDF contains a critical heuristic firing for a malicious redirector link, specifically advertising a 'Coin Master Claim Free Spins' hack. The embedded URL, http://netcdn.tw/app/406889139/coin-master-claim-free-spins-game-hack, is also flagged as malicious. The document body reinforces this lure with text like 'Coin Master Claim Free Spins' and 'CLICK HERE TO ACCESS COIN MASTER GENERATOR', indicating a phishing or scam attempt.

PDF links to a 'free generator / game hack' redirector critical 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. 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_LINKPDF 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.
