The PDF document contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic. The primary purpose appears to be SEO manipulation or redirecting users to potentially malicious content hosted on the 'weisncio.myhome.cx' domain. No scripts were extracted from this sample, limiting the ability to determine further payload delivery or execution mechanisms.

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.
