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

The PDF file contains a heuristic firing for a large number of external PDF links, indicating a link farm. The document body, though heavily obfuscated, contains numerous URLs pointing to PDF files hosted on www.gorillawalker.com. This suggests the primary purpose is to direct users to a large collection of external documents, 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.
