MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF contains a large number of embedded links to external PDF files hosted on various domains, a technique often used for SEO poisoning or to redirect users to malicious content. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' and the 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 link farm designed to lure victims.

  • 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.
