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

The PDF contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic. These links, all pointing to www.gorillawalker.com, suggest a link farm or SEO poisoning tactic. The SE_DOWNLOAD_BUTTON heuristic also indicates the presence of a call-to-action phrase, further supporting the idea that the document is designed to trick users into clicking these links. The primary intent appears to be directing users to external resources, likely for malicious download or redirection.

Heuristics 3

  • 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.
  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • 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.
