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

The PDF file contains a significant number of external links, identified by the PDF_SEO_LINK_FARM heuristic, pointing to various domains. The document body, though heavily obfuscated, contains text related to 'budgetary reporting requirements' and the authoring application 'wkhtmltopdf', suggesting a lure to trick users into visiting these linked sites. The primary intent appears to be driving traffic to a link farm for SEO or potentially malicious redirection.

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.
