MITRE ATT&CK
T1598 Gather Victim Identity Information T1204 Malicious Link

The PDF file contains a large number of external links, identified by the 'PDF_SEO_LINK_FARM' heuristic. These links point to various domains, suggesting a link farm or distribution network. The document body, though heavily corrupted, contains a URL that is also present in the list of extracted URLs. No scripts were extracted from this sample. The primary function appears to be redirecting users to other potentially malicious or SEO-manipulated 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.
