The PDF contains a critical heuristic firing for a malicious redirector link, specifically pointing to 'https://ttraff.cc/pify?keyword=energia+eolica+pdf+unam'. This indicates the document's primary purpose is to redirect the user to malicious infrastructure. Additionally, a heuristic for a PDF link farm was triggered, suggesting the document is designed to host numerous external links, likely for SEO manipulation or to distribute further malicious content. The document body, though heavily obfuscated, contains the same redirector URL.

Heuristics 3

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK
    PDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
  • 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.
