T1566.001 Spearphishing Attachment
T1203 Exploitation for Client Execution
The PDF document contains multiple links to known malicious redirectors, disguised as offers for free in-game currency. The primary lure, 'free-coins-on-coin-master-game-hack', directs users to http://netcdn.tw/app/406889139/free-coins-on-coin-master-game-hack, which is flagged as malicious infrastructure. The document body and embedded links suggest a social engineering tactic to trick users into visiting these malicious sites, likely for further exploitation or credential harvesting.

Heuristics 4
-
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.
-
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
