MITRE ATT&CK

The PDF contains a large number of embedded external links, as indicated by the PDF_SEO_LINK_FARM heuristic. The ML classifier also flagged the PDF as malicious. While no scripts were extracted, the sheer volume of links suggests a malicious intent, possibly for SEO abuse or to distribute further malicious content. The presence of numerous PDF links points towards a link farm strategy.

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.
