MITRE ATT&CK
T1059.001 PowerShell

The PDF file contains a large number of embedded URLs, forming a link farm. The ML classifier strongly suggests maliciousness. The primary attack pattern involves directing users to a collection of external PDF documents, likely for SEO manipulation or to host malicious content. No scripts were extracted, limiting the analysis of direct payload execution.

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.
