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

The PDF file contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic. These links all point to PDF files hosted on www.gorillawalker.com. The document body is heavily obfuscated and unreadable, providing no direct clues to its intent. The primary attack pattern appears to be the distribution of a large number of links, potentially to manipulate search engine results or to serve as a landing page for further malicious activity.

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.
