MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains a large number of embedded links to other PDF files, a technique often used for SEO manipulation or to redirect users to malicious content. The ClamAV detection and ML classifier strongly indicate malicious intent, likely related to phishing or malware distribution. No scripts were extracted, but the primary attack vector appears to be the mass distribution of links.

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • 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.
