MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF file contains a large number of embedded URLs, forming a link farm. The primary heuristic indicates this is a PDF_SEO_LINK_FARM, suggesting the document's purpose is to direct users to numerous external sites, likely for SEO manipulation or to host malicious content. No scripts were extracted from this sample. The embedded URLs, while many are marked as benign, are the primary indicators 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.
