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

The PDF contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic. The ML classifier and ClamAV detection strongly indicate malicious intent, specifically classified as Pdf.Phishing.TtraffRobotInstall. The document body, though heavily obfuscated, contains references to these external URLs, suggesting the primary purpose is to redirect users to a network of malicious or SEO-abused sites.

  • 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.
