MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF document contains multiple links, with a primary focus on luring users with promises of game hacks and free items for Roblox. The heuristic 'PDF_GAME_HACK_REDIRECT_LURE' strongly suggests this malicious intent. While no scripts were explicitly extracted, the presence of embedded URLs and the nature of the lure indicate a phishing or redirection attack, likely leading to a malicious website for further exploitation. The document's creation by wkhtmltopdf suggests it might be a generated document rather than a typical user-authored one.

Machine Learning

  • Nyx PDF Classifier malicious score 0.8852

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.
