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

The PDF contains a large number of embedded links to external PDFs hosted on various domains, a technique often used for SEO manipulation or to distribute malicious content. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' strongly suggests a phishing or traffic redirection intent. The document body, though heavily obfuscated, contains references to URLs that are likely part of this link farm, indicating a coordinated effort to direct 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.
