MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains a heuristic firing for a link farm, indicating a large number of embedded URLs. The document body confirms the presence of these URLs, which are disguised as book titles, likely to trick users into visiting them. The primary attack pattern involves SEO poisoning and link farming to drive traffic to potentially malicious sites.

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.
