T1566.001 Spearphishing Attachment

The PDF contains a heuristic firing for a link farm, indicating a large number of external PDF links. The ML classifier also flagged the document as malicious. While no scripts were explicitly extracted, the nature of the PDF and the embedded URLs suggest it's designed to redirect users to a malicious website, potentially for phishing or malware distribution.

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.
