Maya Secure User Setup Checksum Verification -

If you want, I can produce a ready-to-run verification script for your platform (Windows PowerShell, macOS/Linux shell, or a cross-platform Python script) using SHA-256 and optional GPG signature verification.

Step 3: Implementing Python Checksum Verification for Studio Pipelines

The directory holding your master configuration files must be strictly locked down. Artists should only have read and execute permissions on network pipeline paths. Write access must be restricted exclusively to pipeline administrators and automated deployment systems. Centralized Hash Management

When you download Autodesk Maya, the installer is large. Network interruptions or server errors can corrupt the file. Furthermore, malicious actors sometimes modify software installers to include malware. maya secure user setup checksum verification

Avoid hardcoding hash values directly into local client scripts whenever possible. Instead, store your authorized hashes in a secure, central repository, such as:

Checksum verification is a vital layer of defense, but it is one part of a broader security strategy. Autodesk and the community provide additional tools and configurations that work synergistically with checksum verification:

Maya searches for these files within the user's local directory standard paths (e.g., Documents/maya/scripts ). If a user opens a compromised 3D scene file downloaded from an untrusted source, embedded malicious script nodes (like scriptNode or expression nodes) can silently write unauthorized code into the local userSetup files. If you want, I can produce a ready-to-run

Handling mismatches and errors

What (Windows, Linux, macOS) your studio runs? Do you use a pipeline manager like Rez or ShotGrid?

is a built-in security feature designed to protect your Maya installation from malicious scripts that target the startup process. It specifically monitors the userSetup.py and userSetup.mel files, which are scripts that Maya automatically runs every time it launches. Why This Verification Exists Write access must be restricted exclusively to pipeline

To enable the userSetup checksum verification in Maya, follow these steps:

: When you enable this feature in Windows > Settings/Preferences > Preferences > Security , Maya will check these startup files against known safe signatures or warn you if they have been modified unexpectedly.
