The PDF file contains a heuristic indicating it's a lure for a password-protected archive, suggesting a delivery mechanism to hide a malicious payload. It also embeds a URL that could be used for further stages of the attack. No scripts were extracted from this sample, limiting the ability to determine specific execution methods.

    Document gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
  • 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.
