The PDF document contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic. The document body contains the text 'La mafia medica audiolibro' and references wkhtmltopdf, suggesting a lure related to an audiobook. The primary function appears to be directing users to a vast network of linked PDF files hosted on various domains, likely for SEO spam or to distribute further malicious content.

Heuristics 3

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
