MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded external links, identified as a link farm, which is a common tactic for phishing or distributing malware. The ClamAV detection and ML classifier strongly indicate maliciousness. While no scripts were explicitly extracted, the PDF structure and embedded URLs suggest an attempt to redirect users to malicious content, likely for credential harvesting or further malware delivery.

  • 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.
