The PDF document was flagged by a machine learning classifier and contains a large number of embedded links to external PDF files, suggesting a link farm or redirection scheme. The primary purpose appears to be directing users to potentially malicious websites hosted on calistazz.myhome.cx. No scripts were extracted, but the embedded links are the main vector for potential compromise.

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.
