The PDF file contains a large number of external links, indicating a link farm or redirection scheme. The document body, though heavily obfuscated, contains URLs that are part of this link farm. The primary heuristic firing, PDF_SEO_LINK_FARM, confirms the presence of numerous external links, suggesting a malicious intent to direct users to potentially harmful websites.

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.
