MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded URLs and a document body that promotes downloading game hacks, indicating a lure for potentially malicious content. The ML classifier also flagged this PDF as malicious with high confidence. While no scripts were explicitly extracted, the presence of embedded URLs suggests an attempt to redirect the user to download a second-stage payload.

  • 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.
