MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF contains a large number of embedded links to external PDF files, disguised as literary works. This technique is often used to drive traffic to malicious sites or to host further stages of an attack. The ML classifier strongly indicated maliciousness, and the PDF_SEO_LINK_FARM heuristic confirms the suspicious link distribution.

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.
