The PDF contains a link farm designed to appear as legitimate documents, but the primary URL redirects to malicious infrastructure. The heuristic PDF_MALICIOUS_REDIRECTOR_LINK indicates the initial URL is a known malicious redirector. The embedded URLs, including the malicious redirector https://ttraff.cc/wix?keyword=intermatic+timer+st01, are likely used to deliver a secondary payload or phish for credentials.

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.
