BlendScan is a security addon designed to protect against malicious scripts embedded within .blend files. It provides automated threat detection by analyzing Python scripts, text blocks, animation drivers, and node setups before they are allowed to execute. The tool automatically disables auto-run capabilities and monitors file loads for potential risks.

The addon utilizes a four-level risk assessment system to categorize threats based on patterns such as network activity, system access, and obfuscation techniques like Base64 encoding. It integrates directly into the Text Editor with a dedicated panel for manual scanning and secure script execution, while also offering automated protections that can immediately close the application if critical threats are detected.
