MITRE ATT&CK
T1059.001 PowerShell

The PDF file contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic, pointing to various domains. These links are likely intended to manipulate search engine results or lead users to malicious content. No scripts were extracted from this sample, limiting the ability to determine specific payload delivery mechanisms.

Heuristics 3

  • 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.
  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
