MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF file contains a heuristic firing for a link farm, with 23 external PDF links embedded within the document. The primary purpose appears to be directing users to a large number of other PDF documents hosted on the same domain. No scripts were extracted, and the document body was unreadable, limiting further analysis of specific user lures.

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.
