MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains lures for game hacks and generators, specifically referencing "Roblox Hack Com". It also includes a high-severity heuristic for an MFA lure, suggesting an attempt to harvest credentials or session tokens. The embedded URLs point to suspicious domains, likely leading to phishing pages or malware downloads. No scripts were extracted, but the PDF structure and heuristics indicate a phishing or credential harvesting attempt.

Machine Learning

  • Nyx PDF Classifier malicious score 0.8642

Heuristics 5

  • 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.
  • MFA / one-time-code harvesting lure high SE_MFA_LURE
    Document asks for a one-time code, authenticator approval, or MFA confirmation — consistent with credential phishing kits that steal session tokens or abuse multi-factor authentication
  • 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.
