MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a heuristic firing for an external URI, suggesting it is designed to redirect users to download content. The ML classifier also flagged this PDF as malicious with high confidence. While no scripts were explicitly extracted, the presence of embedded URLs and the ML detection indicate a high likelihood of malicious intent, possibly to deliver a second-stage payload.

Machine Learning

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.
