MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF document employs a lure related to 'free Roblox accounts' and 'game hacks' to entice users to click on embedded links. The primary link directs to a URL associated with free generators and hacks, suggesting a social engineering tactic to lead users to potentially malicious sites or downloads. No scripts were extracted, but the PDF structure and embedded links indicate a phishing or scam attempt.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9491

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.
