MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded URLs pointing to external PDF files on the domain 'gorillawalker.com'. This is indicative of a link farm, likely for SEO manipulation or to serve as a distribution point for further malicious content. The ML classifier also flagged this PDF as malicious. No scripts were extracted, but the presence of embedded URLs suggests a potential for malicious redirection or content delivery.

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.
