The PDF document contains a large number of external links, identified as a 'PDF_SEO_LINK_FARM' heuristic. The document body contains a reference to 'Dada badmash movie' and metadata indicating it was generated by wkhtmltopdf. The primary attack pattern involves directing users to numerous external URLs, likely for SEO spam or to host malicious content. No scripts were extracted from this sample.

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.
