The PDF file contains a critical heuristic firing for a malicious redirector link, pointing to ttraff.ru. The document body, though heavily obfuscated, contains text related to a 'Pokemon emulator' and includes the malicious URL. Additionally, the PDF exhibits characteristics of a link farm, with numerous embedded URLs, many hosted on Shopify, suggesting an attempt to distribute content or traffic. The presence of a 'Browser extension / update installation lure' heuristic indicates a social engineering tactic to trick users into installing potentially harmful software.

Heuristics 4

  • 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.
  • Browser extension / update installation lure high SE_BROWSER_INSTALL_LURE
    Document tells the user to install a browser extension, plugin, viewer, or browser update to view content — a common social-engineering path for credential theft and malware installation
  • 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.
