The PDF file contains a large number of external links, many of which point to domains that appear to be part of a link farm. The document body, though heavily obfuscated, contains a reference to 'Fall colour report ontario 2018' and a URL that matches one of the extracted external links. This suggests the document is designed to manipulate search engine results or redirect users to potentially malicious content hosted on these external domains.

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.
