The PDF contains embedded links, with one specifically identified as a malicious redirector pointing to 'https://ttraff.cc/pify?keyword=soccer+manager+2020+v0.+1.+6'. This URL is likely used to direct users to a malicious site. The document body, though heavily obfuscated, contains text related to 'Soccer manager 2020', suggesting a lure for software downloads. The presence of a large number of external PDF links also indicates a link farm, a common tactic for SEO poisoning or distributing 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.
