MITRE ATT&CK

T1566.001 Spearphishing Attachment

This PDF document employs a common lure of free game hacks and in-game currency to entice users. It contains multiple links to external websites, including one identified as a redirector for game hacks. The document's structure and embedded URLs suggest it is designed to lead users to potentially malicious sites, likely for further exploitation or credential harvesting. No scripts were extracted, but the PDF's nature and embedded links strongly indicate a phishing or scam attempt.

Heuristics 4

PDF links to a 'free generator / game hack' redirector high 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.
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
External URI info PDF_URI

PDF contains an external URL action
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.
