T1059.001 PowerShell

The PDF file was flagged by a machine learning classifier and contains a large number of embedded external links, characteristic of a link farm or SEO poisoning attack. While the document body is heavily obfuscated, the presence of numerous URLs suggests an attempt to distribute or redirect users to other content. 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.
