This detection rule monitors changes to the WDigest credential provider settings in the Windows registry, specifically the 'UseLogonCredential' property, which is found in HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\WDigest. The rule triggers when it detects that this property has been modified to enable the storage of logon credentials in clear text. Enabling this setting can make systems vulnerable to credential theft by allowing attackers to capture sensitive plaintext passwords, leading to potential unauthorized access and further attacks like lateral movement within a network. By detecting such changes, security teams can respond proactively to mitigate the risk of credential-related attacks.
