MITRE ATT&CK
T1059.001 PowerShell

The PDF file contains a large number of embedded URLs, forming a link farm. The heuristic 'PDF_SEO_LINK_FARM' indicates that the document is designed to direct users to numerous external PDF files, likely for SEO manipulation or to host malicious content. While no scripts were extracted, the sheer volume of links suggests a malicious intent to redirect users to potentially harmful sites.

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.
