MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF was flagged by a machine learning classifier and contains a large number of embedded URLs pointing to external PDF files. The heuristic PDF_SEO_LINK_FARM indicates a mass link farm, suggesting the document's primary purpose is to redirect users to these external resources. No scripts were extracted, and the document body was unreadable, limiting further analysis of the immediate intent beyond redirection.

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.
