MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains a large number of embedded links pointing to external PDF documents, a technique often used for SEO poisoning or to distribute malicious content. While the extracted URLs themselves are currently marked as benign, the sheer volume and structure suggest a malicious intent to drive traffic or potentially host malicious content. No scripts were extracted from this sample.

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.
