VBScript Encoded script is a proprietary format developed by Microsoft to provide basic source code obfuscation for Windows script files. It is primarily utilized by system administrators for automating tasks and managing Windows-based environments while protecting proprietary logic from casual observation. As a legacy format, it poses significant security risks because the encoding mechanism is easily reversible yet frequently masks malicious code from traditional signature-based detection systems.
