MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF file contains a large number of embedded URLs pointing to external PDF documents, a technique often used for SEO poisoning or to distribute further malicious content. The ML classifier also flagged this PDF as malicious. No scripts were extracted from this sample, and the document body was not sufficiently readable to determine a 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.
