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

The PDF file exhibits a critical heuristic firing for a 'PDF_SEO_LINK_FARM', indicating a large number of external links. These links predominantly point to PDF files hosted on 'www.gorillawalker.com'. The document body confirms the presence of these embedded URLs. This pattern suggests an attempt to manipulate search engine results or distribute further malicious content via these 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.
