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 the ML_NYX_PDF_MALICIOUS classification suggest a malicious intent, likely to manipulate search engine results or redirect users to harmful sites. The DOC BODY section contains obfuscated text and URLs, further supporting the malicious classification.

Heuristics 2

  • 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.
