MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a prominent external URI pointing to a suspicious domain, likely intended to deliver a payload. The presence of a 'download button' heuristic and the ML classifier's high confidence score indicate a malicious intent to trick the user into downloading a file. Although no scripts were explicitly extracted, the PDF structure suggests potential for embedded JavaScript to facilitate the download.

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.
