MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF contains a mass external link farm, directing users to 32 different PDF files hosted on www.gorillawalker.com. This technique is often used for SEO manipulation or to distribute malicious content indirectly. No scripts were extracted, and the document body was not readable, limiting further analysis of the specific lure.

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.
