The PDF contains a large number of embedded links, identified as a link farm, pointing to a redirector URL. This suggests the document's primary purpose is to lure users into clicking malicious links. The redirector URL `https://ttraff.cc/pify?keyword=whirpool+cabrio+manual` is flagged as malicious. The document body contains garbled text but also includes the same redirector URL and several benign-looking Shopify URLs, likely part of the link farm.

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.
