T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded links, identified by the PDF_SEO_LINK_FARM heuristic, suggesting a link farm or SEO manipulation tactic. While the document body is unreadable, the presence of numerous external links points towards an attempt to direct users to potentially malicious or deceptive content. The ML_NYX_PDF_MALICIOUS heuristic further supports the malicious classification.

  • 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.
