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

The PDF contains a heuristic firing for PDF_SEO_LINK_FARM, indicating a large number of external links. The document body, though heavily obfuscated, contains numerous URLs pointing to PDF files on the domain www.gorillawalker.com. This suggests the primary function is to act as a link farm, potentially for SEO manipulation or to distribute further malicious content disguised as legitimate documents.

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.
