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

The PDF contains a large number of embedded links to external PDF files, all hosted on the domain www.gorillawalker.com. This is indicative of a link farm or SEO manipulation tactic. While no scripts were extracted, the sheer volume of links suggests an attempt to drive traffic or distribute potentially malicious content disguised as legitimate documents. The attack pattern is likely to trick users into clicking these links, leading them to a large collection of PDFs.

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.
