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

The PDF file contains a heuristic firing for PDF_SEO_LINK_FARM, indicating a large number of external links. These links point to various PDF files hosted on the domain www.gorillawalker.com. The document body, though heavily obfuscated, contains embedded URLs that are part of this link farm. This suggests the primary purpose is to direct users to a large collection of external resources, potentially for SEO manipulation or to serve as a distribution point for further malicious content.

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.
