MITRE ATT&CK
T1566.001 Phishing: Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of embedded links pointing to external PDF documents hosted on a dynamic DNS domain. This technique is often used for SEO poisoning or to drive traffic to malicious sites. No scripts were extracted from this sample, and the document body was heavily obfuscated, limiting further analysis of the specific lure.

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.
