MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded URLs and document body text that mimic download lures for popular games, aiming to trick users into downloading further malicious content. The ML classifier strongly flagged this PDF as malicious, and the presence of multiple external URLs suggests a downloader or redirector pattern. No scripts were extracted from this sample, but the overall structure and content point towards a phishing or malware distribution attempt.

  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
