MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains a large number of embedded URLs pointing to external PDF documents, as indicated by the PDF_SEO_LINK_FARM heuristic. This suggests a link farm or SEO manipulation tactic. The ML classifier and ClamAV detection further support its malicious nature, flagging it as phishing or a potential installer. No scripts were extracted, but the sheer volume of outbound links is the primary indicator of malicious intent.

  • 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.
