This detection rule monitors for the unauthorized removal of folders from the ProtectedFolders list in Windows Defender's Exploit Guard. The ProtectedFolders feature is designed to shield sensitive directories from unauthorized modifications, particularly from malicious software attempting to encrypt or manipulate data. When a folder is deleted from this list, it may signal that an attacker is gaining leverage over protected files, thereby elevating the risk of data corruption or ransomware attacks. This rule is crucial for identifying possible defense evasion tactics employed by adversaries, especially in high-value environments where data integrity is paramount. It is intended for environments that utilize Windows operating systems and require stringent monitoring of critical security settings related to folder protection.
