MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a large number of embedded links pointing to external PDF files. These links are hosted on a dynamic DNS domain, suggesting a link farm or redirection scheme. The ML classifier also flagged this PDF as malicious, supporting the suspicious nature of the embedded content. No scripts were extracted, and the document body was heavily obfuscated, making it difficult to determine a more specific attack pattern beyond the link farm.

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.
