MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF contains a large number of embedded links to other PDF files hosted on various domains, as indicated by the PDF_SEO_LINK_FARM heuristic. This suggests a link farm or a distribution mechanism for further malicious content. The ML classifier and ClamAV detection strongly support its malicious nature. No scripts were extracted, and the document body was heavily truncated and unreadable, making it impossible to determine a more specific attack pattern or intent beyond link distribution.

  • 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.
