MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains an embedded URI pointing to a suspicious URL that appears to be a game hack download. The ML classifier also flagged this PDF as malicious. While no scripts were explicitly extracted, the presence of embedded URLs and the overall structure suggest an attempt to trick the user into downloading a second-stage payload.

  • 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.
