MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious File

The PDF file exhibits characteristics of a link farm, containing numerous embedded URLs pointing to external PDF documents. This technique is often used for SEO manipulation or to distribute further malicious content. No scripts were extracted, and the document body was not parsable, limiting the ability to determine a more specific attack pattern or family. The primary IOCs are the extensive list of linked URLs.

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.
