The PDF file contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic. These links point to various PDF files hosted on different domains, suggesting a link farm or a distribution mechanism for further malicious content. The document body contains garbled text along with some of the URLs, indicating a potential attempt to disguise the malicious nature of the links. No scripts were extracted from this sample.

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.
