MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure for game hacks, specifically mentioning 'Roblox Hacks 2021 Aimbot'. It includes numerous embedded URLs that redirect to websites offering such cheats or related game exploits. The primary malicious URL identified is http://netcdn.co/app/431946152/roblox-hacks-2021-aimbot-game-hack, which likely serves as a landing page for malware or further phishing attempts. No scripts were extracted, but the document's structure and embedded links strongly indicate a social engineering attack.

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.
