MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of embedded links to external PDF documents, as indicated by the PDF_SEO_LINK_FARM heuristic. While most of these links were classified as benign, the sheer volume and the nature of the heuristic suggest a malicious intent, possibly for SEO manipulation or to distribute further malicious content. The ML_NYX_PDF_MALICIOUS classifier also flagged the document with high confidence.

Heuristics 2

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
  • 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.
