MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic. While the document body is heavily obfuscated, the presence of numerous links suggests an attempt to manipulate search engine results or redirect users to potentially malicious content. The ML_NYX_PDF_MALICIOUS heuristic further supports the malicious nature of this file.

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • 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.
