The PDF file contains a heuristic match for PDF_MALICIOUS_REDIRECTOR_LINK, indicating it directs users to malicious infrastructure. The document body, though heavily obfuscated, contains a URL that appears to be a lure for free online content, aligning with the redirector link. The presence of numerous embedded links, identified by PDF_SEO_LINK_FARM, further supports the malicious intent of directing users to external sites. The primary IOC is the malicious redirector 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.
