MITRE ATT&CK
T1059.001 PowerShell

The PDF file contains a large number of embedded URLs, constituting a link farm. The primary heuristic indicates a 'PDF_SEO_LINK_FARM' with 32 external PDF links, suggesting a tactic to drive traffic or distribute content through SEO manipulation. The ML classifier also flagged the document as malicious with high confidence. No scripts were extracted, and the document body was unreadable, so the rationale is based solely on the link farm heuristic.

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.
