MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded external links, identified as a link farm. The primary heuristic indicates this is a critical finding, suggesting the document's purpose is to drive traffic to these external resources. While the URLs themselves are currently marked as benign, the sheer volume and nature of the links suggest a malicious intent, likely to distribute further malicious content or engage in SEO manipulation.

Heuristics 2

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • 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.
