MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure related to hacking Roblox, with an embedded URL pointing to a suspicious domain. The ML classifier strongly flagged this PDF as malicious. While no scripts were directly extracted, the presence of an external URI and the document's content suggest an attempt to trick the user into downloading a second-stage payload.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9980

Heuristics 3

  • 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.
