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 these links are likely intended for SEO manipulation or to serve as a distribution point for malicious content. No scripts were extracted from this sample, and the document body is heavily obfuscated, making it difficult to determine the exact malicious intent beyond the link farm. The primary IOCs are the numerous external URLs.

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.
