MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly indicates maliciousness, and the document contains an embedded URI pointing to a suspicious URL. The presence of a visual download button lure, combined with the external URI, suggests the document is designed to trick users into downloading a second-stage payload. No scripts were extracted from this sample, limiting the ability to determine specific execution methods.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9874

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.
