MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF contains a large number of embedded external links, as indicated by the PDF_SEO_LINK_FARM heuristic. While many of these links resolve to benign content, the sheer volume and structure suggest a malicious intent, possibly for SEO manipulation or to serve as a landing page for further malicious activity. The ML classifier also strongly flagged this PDF as malicious. No scripts were extracted from this sample.

  • 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.
