T1566.001 Spearphishing Attachment
This PDF document contains multiple links that redirect to malicious infrastructure, specifically promoting 'free generators' and 'game hacks' for popular mobile games. The ML classifier strongly indicated maliciousness, and the embedded URLs are associated with known redirector patterns. The document body, though partially corrupted, contains text related to 'Coin Master Free Chip' and references the malicious URL, reinforcing the lure-based attack pattern.

Heuristics 3
-
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.
