Use the maya secure manifest command to create a checksum manifest from a clean reference directory:
Maya automatically searches for and executes specific initialization scripts when it boots. This feature helps pipeline technical directors (TDs) configure environments, load plugins, and set paths. However, it also introduces a significant security risk. Script Execution Order

If the checksum you generated does not match the one provided by Autodesk: Delete the downloaded file. Clear your browser cache.
Re-download the installer from the official Autodesk source.
During user setup, data transits between the user’s device, the Maya authentication server, and possibly third-party identity providers. An attacker could intercept and modify configuration files (e.g., redirecting API endpoints to a fake server). Checksum verification ensures that any such modification invalidates the setup process.

Checksum verification is useless if an attacker can modify the bootstrapper script itself.

Maya Secure User Setup: Checksum Verification Guide Autodesk Maya is a cornerstone of the visual effects and animation industries. Its flexibility relies heavily on customization scripts like userSetup.py and userSetup.mel . However, pipeline flexibility introduces significant security vulnerabilities. Malicious actors frequently target these startup scripts to execute unauthorized code across studio networks. Implementing checksum verification for your Maya user setup environment is the most effective way to guarantee script integrity and protect your pipeline.

Maya automatically executes any userSetup.py or userSetup.mel file it finds within its script paths upon initialization. This feature is incredibly useful for technical directors (TDs) to initialize tools, set environment variables, and load plug-ins automatically.
