The PDF contains multiple external URLs, one of which is explicitly flagged as an external URI. The ML classifier also identified the PDF as malicious. The document body is heavily obfuscated and does not provide clear textual lures, but the presence of numerous links suggests a social engineering attempt to direct the user to download content from the 'gorillawalker.com' domain.

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.
