The PDF document contains a large number of embedded links, identified by the PDF_SEO_LINK_FARM heuristic. While the document body is unreadable, the presence of 23 links pointing to a single domain suggests an attempt at SEO manipulation or distributing malicious content. No scripts were extracted from this sample. The primary IOCs are the URLs associated with the link farm.

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.
