The PDF contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic. While the specific content of the document body is heavily obfuscated, the presence of numerous links suggests a malicious intent, likely for SEO manipulation or to distribute further malware. The ML classifier also strongly indicated maliciousness.

Heuristics 2

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • 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.
