MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains an embedded URL pointing to a resource that claims to be a game hack, combined with heuristics indicating an external URI and a visual download button lure. The ML classifier strongly flagged this PDF as malicious. While no scripts were explicitly extracted, the nature of the lure and the embedded URL suggest an attempt to trick the user into downloading a second-stage payload.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9796

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.
