MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded links, identified by the PDF_SEO_LINK_FARM heuristic, pointing to external websites. While the URLs themselves are marked as benign, the sheer volume and structure suggest an attempt to direct users to potentially malicious content or to manipulate search engine rankings. The ML_NYX_PDF_MALICIOUS heuristic further supports the malicious classification.

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.
