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

The PDF file contains a large number of external links, many of which point to other PDF files hosted on various domains. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' and the presence of a download lure suggest a phishing or malware distribution campaign. The embedded URLs are likely part of this campaign to redirect users to malicious content.

  • 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.
