MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious File

The PDF file exhibits a PDF_SEO_LINK_FARM heuristic, indicating a large number of embedded external links. These links predominantly point to PDF files hosted on www.gorillawalker.com. The presence of numerous links suggests an attempt to manipulate search engine results or to distribute a large volume of content, potentially malicious, through a link farm. No scripts were extracted from this sample.

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.
