MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded links pointing to external PDF files on the domain 'www.gorillawalker.com'. This behavior is indicative of a link farm, often used for SEO manipulation or to distribute potentially malicious content. While no scripts were explicitly extracted, the PDF structure and the sheer volume of external links suggest an attempt to redirect users or manipulate search engine results, aligning with a phishing or content distribution attack pattern.

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.
