MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF document contains a large number of embedded links pointing to external PDF files hosted on a dynamic DNS domain. This behavior is indicative of a link farm or a redirection scheme, likely intended to lead users to malicious content or phishing pages. No scripts were extracted, and the document body was heavily obfuscated, making it difficult to determine the exact final payload. The primary IOCs are the numerous URLs found within the document.

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.
