MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure related to 'Robux Hack Xyz' and a call to action to 'CLICK HERE TO ACCESS ROBLOX GENERATOR'. It embeds multiple URLs, with the primary one being https://netsecure.pro/app/431946152/robux-hack-xyz-game-hack, which is likely a redirector to a malicious site. The ML classifier also flagged this PDF as malicious. Although no scripts were explicitly extracted, the PDF structure and embedded links suggest a phishing or scam attempt.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9408

Heuristics 5

  • PDF links to a 'free generator / game hack' redirector critical 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. CRITICAL on its own: the /app/<id>/<slug>-game-hack path shape is unambiguous scam infra, and the host rotates so a host-list match can't be relied on.
  • Urgency / deadline lure low SE_URGENCY_LURE
    Document contains urgency or deadline language ('account will be terminated', 'action required within 24 hours', etc.) — useful context, but low-signal without other findings
  • 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.
