MITRE ATT&CK

T1566.001 Spearphishing Attachment

The PDF document contains a lure for game hacks and free currency, directing users to external URLs. The ML classifier strongly flagged this PDF as malicious. The embedded URLs likely lead to further malicious content or phishing pages, and the document's content and heuristics suggest a social engineering tactic to trick users into clicking malicious links.

Machine Learning

Nyx PDF Classifier malicious score 0.9507

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.
