MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded links to external PDF files, as indicated by the 'PDF_SEO_LINK_FARM' heuristic. The URLs point to a domain that appears to be used for distributing these linked files. While no specific script was extracted, the nature of the embedded links suggests a potential for SEO manipulation or the distribution of further malicious content, possibly via JavaScript if present in the linked documents. The ML classifier also flagged this PDF as malicious.

  • 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.
