MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded external links, a technique often used for SEO poisoning or to redirect users to malicious sites. The ClamAV detection and ML classifier strongly indicate malicious intent, likely to distribute further malware or phishing content. The embedded URL points to a PDF file hosted on a suspicious domain, suggesting a multi-stage attack.

  • 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.
