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 PDF files. While the document body is heavily corrupted, the presence of these links suggests an attempt to direct users to potentially malicious content or for SEO manipulation. The ML_NYX_PDF_MALICIOUS heuristic further supports the malicious nature of the file.

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.
