The PDF file contains a large number of embedded links to external PDF files hosted on various domains. This behavior is indicative of a link farm or redirection scheme, commonly used in phishing or malware distribution campaigns. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a phishing or traffic redirection intent.

  • 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.
