MITRE ATT&CK

The PDF file contains a large number of embedded URLs, identified by the PDF_SEO_LINK_FARM heuristic. These links point to various external websites, suggesting a potential attempt to redirect users or manipulate search engine results. No scripts were extracted, but the presence of embedded URLs and the nature of the heuristic indicate a likely phishing or SEO-based attack vector.

Heuristics 2

  • 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.
