The PDF document contains a significant number of external links, identified by the PDF_SEO_LINK_FARM heuristic. One of these links, http://carividavillas.com/uploads/1/3/0/6/130639312/130639312.html#order+ps+form+2976-e, points to an HTML page which in turn likely leads to further malicious content, as indicated by the PDF_URI firing. The presence of multiple similarly structured URLs hosted on various domains suggests a link farm designed to distribute malicious payloads, likely PDFs, to unsuspecting users.

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.
