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

The PDF file contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic, which is a common technique for distributing malicious content or leading users to phishing sites. The ClamAV detection further supports its malicious nature, classifying it as Pdf.Phishing.TtraffRobotInstall. The presence of a visual download button lure also suggests a deceptive workflow. The document body contains numerous URLs, many of which are hosted on suspicious domains, indicating a phishing or malware distribution attempt.

  • 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.
