In your userSetup.py , implement a check that validates the manifest before loading any other modules. If the userSetup.py itself needs protection, use a launcher (like a .bat or .sh file) to verify the setup script before Maya even opens. 4. Enable Maya’s Internal Security Preferences
The integration of Maya Secure User Setup with checksum verification represents a critical evolution in safeguarding 3D production environments against malicious scripts and supply chain vulnerabilities. As studios increasingly rely on third-party plugins and distributed pipelines, the "userSetup.py" and "userSetup.mel" files have become primary targets for automated malware, such as the "PhysXPluginMfx" exploit. By implementing a rigorous checksum verification architecture, pipeline TDs can ensure that only vetted, untampered code executes during the Maya initialization process, effectively creating a "Trust-But-Verify" gateway for the technical ecosystem. maya secure user setup checksum verification
