A PowerShell v2.0+ compatible command and script obfuscation framework for security testing.
Invoke-Obfuscation is a PowerShell obfuscation framework that systematically explores and generates obfuscated PowerShell commands and scripts. It helps security professionals test their detection capabilities against advanced obfuscation techniques commonly used by attackers and commodity malware. The tool supports a wide range of obfuscation methods, including token manipulation, string encoding, and launch technique abstraction.
Security researchers, red teamers, and blue team defenders who need to simulate or detect obfuscated PowerShell attacks in Windows environments.
Developers choose Invoke-Obfuscation for its comprehensive coverage of PowerShell obfuscation techniques, its ability to break defender assumptions about command-line appearance, and its role in improving detection strategies through realistic simulation.
PowerShell Obfuscator
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Supports token, string, encoding (e.g., ASCII, hex, SecureString), and AST obfuscation, with multiple techniques detailed in the README for thorough simulation.
Offers both CLI for automation and interactive menu-driven usage, allowing flexibility for scripted testing or exploratory learning as mentioned in the usage section.
Includes various launchers like CLIP++, WMIC, RUNDLL, and MSHTA++ to abstract command execution, aiding in evasion technique testing per the features list.
Regular updates since 2016, with versions adding features like AST obfuscation and CLI functionality, showing ongoing refinement and community engagement.
Designed for PowerShell 2.0-5.0, which may not fully support newer versions like PowerShell 7 (Core), limiting its relevance in modern cross-platform environments.
Requires deep knowledge of PowerShell syntax and obfuscation concepts to navigate the complex menu system and effectively utilize all layers, as hinted in the interactive usage instructions.
Generated obfuscated commands can trigger security alerts or be blocked by tools like AMSI, complicating legitimate testing in production-like settings without careful configuration.
