MITRE ATT&CK

The PDF file contains a large number of embedded URLs, identified as a link farm. The ML classifier strongly indicates maliciousness. The primary attack pattern involves leveraging these links, likely to redirect users to malicious websites or for SEO spam. No scripts were extracted, but the PDF structure and URL distribution are highly suspicious.

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.
