MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious File

The PDF file exhibits characteristics of a link farm, with 32 external links pointing to other PDF files on the domain www.gorillawalker.com. This technique is often used for SEO manipulation or to distribute malicious content disguised as legitimate documents. No scripts were extracted, and the document body was heavily obfuscated, limiting further analysis of the specific payload.

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.
