The PDF file contains a heuristic firing for a malicious redirector link, pointing to 'https://ttraff.ru/wix?keyword=monster+truck+games+unblocked'. Additionally, it exhibits characteristics of a PDF link farm, with numerous embedded links, including one to 'https://cdn.shopify.com/s/files/1/0436/1905/7826/files/uppsc_sociology_syllabus.pdf'. The document body, though partially corrupted, contains text related to 'monster truck games' and the malicious URL, suggesting a lure to disguise the malicious redirection. No scripts were extracted from this sample.

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.
