The PDF file contains numerous links, with a critical heuristic identifying a link to a known malicious redirector at 'https://ttraff.ru/pify?keyword=amaryllis+flower+information+in+english'. Another critical heuristic indicates a PDF link farm, with 'https://cdn.shopify.com/s/files/1/0429/2660/4447/files/21071984259.pdf' being the first identified URL. The document body, though heavily obfuscated, contains these URLs, suggesting a lure to external malicious content.

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.
