MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

It contains a mass of external links, suggesting a link farm designed to distribute further malicious content or engage in SEO manipulation. The ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall' further supports its malicious nature. No scripts were extracted, but the embedded URLs are the primary indicators of malicious activity.

  • 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.
