MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a visual download button lure, suggesting an attempt to trick the user into downloading a payload. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs indicates a potential download or redirection to a malicious site. Although no scripts were explicitly extracted, the PDF structure and embedded URIs are indicative of a malicious document, likely a downloader or part of a phishing campaign.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9980

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.
