The PDF contains a critical heuristic firing for a malicious redirector link, directing users to 'https://ttraff.cc/pify?keyword=police+radio+scanner+apps+for+android'. Additionally, it exhibits characteristics of a link farm, with numerous embedded URLs pointing to external PDFs, many hosted on Shopify. The document body, though partially corrupted, contains the same redirector URL and a reference to 'police radio scanner apps for android', suggesting a lure to a malicious site. 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.
