The PDF document contains a mass of external links, masquerading as a resume template, with the primary goal of redirecting users to a malicious URL. The heuristic PDF_MALICIOUS_REDIRECTOR_LINK specifically identifies the initial redirector URL, and the ML classifier strongly indicates maliciousness. The document body, though partially corrupted, contains the lure text 'Ekg technician resume template' and the malicious URL.

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.
