Shield Scan is an anti-backdoor plugin for Roblox Studio designed to help developers detect suspicious scripts commonly found in free models and imported assets.
The plugin scans selected services or the entire game and highlights scripts that match known backdoor patterns.
⚠️ Shield Scan uses heuristic pattern detection.
Flagged scripts are not automatically malicious and should always be reviewed manually.
