MITRE ATT&CK
T1059.001 PowerShell T1204.002 Malicious Link

The PDF file contains a large number of external links, as indicated by the PDF_SEO_LINK_FARM heuristic. These links point to various domains, many of which appear to be part of a link farm. The primary purpose seems to be directing users to these external sites, potentially for SEO manipulation or to serve as a landing page for further malicious activity. No scripts were extracted, and the document body is heavily obfuscated.

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.
