MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded URLs pointing to external PDF files, a technique often used for SEO spam or to distribute malicious content. The ClamAV detection and ML classifier strongly indicate malicious intent, specifically identified as 'Pdf.Phishing.TtraffRobotInstall-7605656-0'. While no scripts were explicitly extracted, the PDF structure and embedded URLs suggest an attempt to redirect users to potentially harmful content.

  • 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.
