MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded URLs pointing to external PDF documents, as indicated by the PDF_SEO_LINK_FARM heuristic. While the document body is heavily obfuscated, the presence of numerous links suggests an attempt to manipulate search engine results or redirect users to potentially malicious content hosted on the gorillawalker.com domain. No scripts were extracted, and the primary malicious behavior appears to be the mass linking.

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.
