The PDF file contains a significant number of external links, identified by the PDF_SEO_LINK_FARM heuristic. These links point to various domains, suggesting a link farm or a method to distribute malicious content. The embedded URL and the document body also contain references to these external sites, reinforcing the attack pattern. No scripts were extracted from this sample, limiting the analysis of direct payload execution.

Heuristics 3

  • 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.
  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
