MITRE ATT&CK
T1598 External Remote Services T1204 User Execution

The PDF file contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic. The document body, though partially corrupted, contains text related to games and the authoring application, suggesting a lure. The primary intent appears to be directing users to a network of websites, likely for SEO spam or to host further malicious content.

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.
