Generate a trusted cryptographic hash (SHA-256) of your master configuration files. Store this manifest in a read-only administrative directory.
Maya Secure’s user setup process now includes three phases:
Securing the Maya user setup process is critical for protecting intellectual property and maintaining system stability across a production studio. By implementing a SHA-256 checksum verification system, you ensure that only authorized, unaltered code runs on your artists' workstations. Combine hash checks with a signed manifest and strict environment variables to create a robust defense capable of stopping pipeline script infections before they start.
: Maya calculates a digital fingerprint (checksum) for your userSetup scripts to ensure they haven't been altered by unauthorized processes or malware. maya secure user setup checksum verification
Prevents common Maya-specific viruses (like PhysXPluginStun ) from persisting in your environment.
By enforcing , you establish a cryptographic trust mechanism. Maya will only execute startup scripts if their mathematical fingerprint matches a trusted, pre-approved master record. How Checksum Verification Works
You cannot rely on userSetup.py to verify itself. If an attacker modifies userSetup.py , they can simply delete the verification code. Instead, you must use a secure bootstrapping architecture. The Corporate Site Initialization Method Generate a trusted cryptographic hash (SHA-256) of your
import hashlib def generate_file_hash(file_path): sha256_hash = hashlib.sha256() with open(file_path, "rb") as f: # Read the file in small chunks to handle any file size efficiently for byte_block in iter(lambda: f.read(4096), b""): sha256_hash.update(byte_block) return sha256_hash.hexdigest() # Replace with the actual path to your clean userSetup.py clean_file = "C:/Users/Username/Documents/maya/scripts/userSetup.py" print(f"Your Master Hash: generate_file_hash(clean_file)") Use code with caution. Step 2: Implement the Secure Bootstrap Script
A is a digital fingerprint of a file. By using hashing algorithms like SHA-256, you can generate a unique string of characters based on the contents of a script. Even a single extra space or a malicious line of code will completely change the resulting hash.
Avoid keeping vital pipeline tools in the local Documents/maya/scripts folder. Instead, host them on a read-only network drive or a version-controlled repository (like Git). This prevents local "drive-by" infections from modifying your core tools. 2. Automate Hash Generation By implementing a SHA-256 checksum verification system, you
Integrate checksum generation into your Git deployment or CI/CD pipeline. Whenever a pipeline TD updates a script, the deployment runner should automatically recalculate the SHA-256 hash and update the allowed_hashes.json manifest. 2. Implement the "Principle of Least Privilege"
Modern versions of Maya include a native window (introduced via the MayaScanner plugin framework). Ensure that: Security Execution Mode is set to Strict . Only explicit, trusted plugin paths are whitelisted. 2. Restrict Write Permissions

) that needs to modify these scripts, Maya detects the change and throws a dialog: "UserSetup Checksum Verification"
Maya calculates a "checksum"—a digital fingerprint—of your original : If you install a legitimate tool (like
