MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic. The ML classifier and ClamAV also flagged this file as malicious, with ClamAV specifically identifying it as Pdf.Phishing.TtraffRobotInstall. The embedded URLs likely lead to malicious content or phishing sites, and the document body is heavily obfuscated, preventing analysis of its specific intent beyond link distribution.

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • 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.
