MITRE ATT&CK
T1566.001 Phishing: Spearphishing Attachment T1059.001 Command and Scripting Interpreter: PowerShell

The PDF document exhibits characteristics of a link farm, containing numerous embedded URLs that point to other PDF files. This technique is often used for SEO manipulation or to distribute malicious payloads disguised as legitimate documents. No scripts were extracted, and the document body primarily consists of these URLs and associated metadata. The primary attack pattern observed is the creation of a link farm, likely to direct users to potentially harmful content.

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.
