MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF contains a large number of external links to other PDF files, a technique often used to distribute malware or facilitate phishing campaigns. The heuristic 'PDF_SEO_LINK_FARM' and ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' strongly indicate malicious intent. The embedded URLs are likely part of this link farm, serving as the primary mechanism for further infection or redirection.

  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • 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.
