MITRE ATT&CK
T1059.001 PowerShell

The PDF file contains a large number of embedded URLs pointing to external PDF documents, characteristic of a link farm. The heuristic 'PDF_SEO_LINK_FARM' confirms this behavior, indicating a potential attempt to manipulate search engine results or distribute malicious content indirectly. While the URLs themselves are currently marked as benign, the sheer volume and the nature of the link farm suggest a malicious intent, possibly to host malicious content that could change over time. No scripts were extracted from this sample.

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.
