Maya Secure - User Setup Checksum Verification

Restrict file system and registry/daemon access.

Ransomware often encrypts or alters system files. By verifying checksums of critical user setup binaries before execution, Maya Secure can detect anomalies even before decryption attempts occur.

  • Validate the checksum file authenticity (when signatures available)

  • Confirm the signer’s key fingerprint matches the vendor’s published fingerprint.

  • Compute local file checksums

  • Compare computed hashes to trusted values

  • Handling mismatches and errors

  • Automating verification in setup workflows

  • Audit and logging

  • Key management and rotation (when using signatures)

    • The process is not a single step but a pipeline of verification checkpoints. Below is a step-by-step breakdown of Maya’s implementation.

    When a user initiates secure setup, the Maya app requests a manifest file from the API endpoint v1/setup/manifest. This manifest contains: maya secure user setup checksum verification

    The app validates the manifest’s digital signature (RSA or ECDSA) before trusting its checksums.

    A checksum is a small-sized block of data derived from a larger digital input (like a file, a configuration string, or a memory block) using a cryptographic hash function (e.g., SHA-256). Verification is the process of recomputing that checksum and comparing it to a known, trusted value.

    In simple terms: If even one character changes in the original data, the checksum changes completely.

    Security is meaningless if users disable it. Maya balances rigor with usability:

    Create a login script that runs checksum verification before Maya launches. Restrict file system and registry/daemon access

    Windows (PowerShell script Verify-Maya.ps1):

    $expected = Get-Content "\\secure\maya_checksums.txt" | ConvertFrom-StringData
$mayaPath = "C:\Program Files\Autodesk\Maya2024\bin\maya.exe"
$actual = (Get-FileHash $mayaPath -Algorithm SHA256).Hash

    if ($actual -ne $expected['maya.exe']) 
Write-EventLog -LogName Application -Source "Maya Security" -EventId 1001 -Message "Checksum mismatch! Maya blocked."
Exit 1
Start-Process $mayaPath

    Linux (bash script /usr/local/bin/secure_maya):

    #!/bin/bash
cd /usr/autodesk/maya2024/bin || exit 1
sha256sum -c /secure/maya_checksums.sha256 --quiet
if [ $? -ne 0 ]; then
    logger "Maya checksum verification failed for user $USER"
    zenity --error --text="Maya integrity check failed. Contact security."
    exit 1
