The PDF file contains numerous external links, with a critical heuristic firing for a 'PDF_SEO_LINK_FARM'. This indicates a technique to mass-link to external sites, likely for SEO manipulation or to distribute malicious payloads. One of the primary external URIs identified is http://gz9c2.slpny.com/uploads/1/3/0/6/130621426/130621426.html#gungeon+platinum+bullets. The document body is heavily obfuscated and contains metadata suggesting it was generated by wkhtmltopdf, a tool sometimes used to create malicious PDFs.

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.
