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

The PDF file was flagged by a machine learning classifier and contains a large number of embedded links, characteristic of a link farm or SEO poisoning attack. The primary heuristic indicates a 'PDF_SEO_LINK_FARM' with 21 external links, suggesting the document's purpose is to distribute these links. While the extracted URLs are currently marked as benign, the sheer volume and the critical heuristic firing strongly suggest a malicious intent to redirect users to potentially harmful content.

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.
