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

The PDF contains a large number of embedded links, as indicated by the PDF_SEO_LINK_FARM heuristic. While the document body is unreadable, the presence of numerous links suggests a malicious intent, possibly for SEO manipulation or to distribute further malware. The ML_NYX_PDF_MALICIOUS classifier also strongly indicates maliciousness. The URLs themselves appear to be benign, but their sheer quantity and the context of the PDF suggest a link-farming or redirection scheme.

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.
