MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded links to external PDF files hosted on the domain 'gorillawalker.com'. This is indicative of a link farm or SEO manipulation tactic. While no scripts were explicitly extracted, the PDF structure and the sheer volume of external links suggest an attempt to drive traffic or distribute content, potentially malicious, through indirect means. The ML classifier also flagged this PDF as malicious.

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.
