MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains multiple embedded URLs and a heuristic firing for an external URI, all pointing to potentially malicious download sites related to games. The ML classifier also flagged the PDF with high confidence. While no scripts were directly extracted, the presence of these links and the document's structure suggest an attempt to trick the user into downloading a payload.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9900

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.
