MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and text that mimic download lures for popular games, aiming to trick users into clicking malicious links. The ML classifier strongly indicates malicious intent, and the presence of external URIs suggests the document is designed to redirect users to potentially harmful sites. No scripts were extracted, but the overall structure and content point to 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.
