MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF was flagged by a machine learning classifier and contains a large number of embedded external links, characteristic of a link farm. The primary heuristic indicates a 'PDF_SEO_LINK_FARM' with 32 external PDF links, suggesting the document's purpose is to drive traffic to these external resources. No scripts were extracted, and the document body was unreadable, but the link farm itself is the primary indicator of malicious intent.

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.
