MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a large number of embedded external links, suggesting a link farm or phishing attempt. The ML classifier also flagged the document as malicious. While the specific intent of these links is unclear, the sheer volume and the heuristic firing indicate a malicious attempt to redirect users. 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.
