MITRE ATT&CK

The PDF contains a large number of embedded links, identified by the PDF_SEO_LINK_FARM heuristic, suggesting a phishing or malware distribution attempt. The ClamAV detection as Pdf.Phishing.TtraffRobotInstall-7605656-0 further supports this. The primary malicious URLs are hosted on `jar.deevki.icu` and `designsbycarolann.com`, likely serving as lures for further malicious 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.
