MITRE ATT&CK

T1566.001 Spearphishing Attachment

The PDF document contains a heuristic indicating it links to a game hack lure, specifically pointing to a URL associated with 'pokemon-go-no-free-box-game-hack'. This suggests a social engineering tactic to trick users into visiting a potentially malicious site. No scripts were extracted, but the presence of embedded URLs and the lure itself 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.
