MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains a large number of embedded URLs pointing to other PDF files hosted on various domains. This behavior is indicative of a link farm or a distribution mechanism for further malicious content, as flagged by the PDF_SEO_LINK_FARM heuristic and ClamAV detection. While no scripts were explicitly extracted, the embedded URLs are the primary indicators 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.
