MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple links and text referencing 'free Robux' and 'game hacks', indicating a lure for users interested in such topics. The heuristic 'PDF_GAME_HACK_REDIRECT_LURE' confirms this, pointing to a redirector URL. While no scripts were explicitly extracted, the nature of the lure and the embedded URLs suggest a phishing or scam attempt to redirect users to malicious sites.

  • Nyx PDF Classifier malicious score 0.9466

Heuristics 3

  • 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.
  • 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.
