MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links and a document body referencing game hacks and cheats, specifically for Roblox and Minecraft. The heuristic 'PDF_GAME_HACK_REDIRECT_LURE' confirms this is a lure to a redirector. While no scripts were explicitly extracted, the presence of embedded URLs and the nature of the lure strongly suggest an attempt to trick users into downloading malicious content, likely leading to malware infection. The primary attack pattern observed is a phishing lure for game-related exploits.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9980

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.
