The PDF file contains a link to a known malicious redirector. The heuristic 'PDF_MALICIOUS_REDIRECTOR_LINK' directly indicates this malicious behavior. The embedded URL is likely intended to lure the user into visiting a site that could lead to credential theft or further malware infection. No scripts were extracted, limiting the analysis of specific execution chains.

Heuristics 2

  • 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.
  • 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.
