MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF contains a large number of embedded links, forming a link farm. The heuristic PDF_SEO_LINK_FARM indicates that these links are designed to direct users to external PDF files, likely for SEO manipulation or to host malicious content. While the specific URLs extracted were classified as benign, the sheer volume and structure suggest a malicious intent to drive traffic or distribute further payloads.

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.
