The sample is a malicious Office document containing an embedded PE executable. Heuristics indicate the use of Windows Script Host, CreateProcess, ShellExecute, and LoadLibrary APIs, suggesting the embedded executable is likely dropped and executed. The presence of the embedded executable is the primary indicator of malicious intent.

  • Suspicious extracted artifact medium EXTRACTED_FILE_STATIC_TRIAGE
    One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
  • Embedded URL info EMBEDDED_URL
