MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF file contains a large number of embedded links pointing to external PDF documents on the domain www.gorillawalker.com. This behavior is indicative of a link farm or SEO spam technique, likely intended to drive traffic or host malicious content indirectly. No scripts were extracted, and the document body was heavily obfuscated, making it difficult to determine the exact payload or user interaction intended beyond clicking the links.

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.
