Windows Defender Submit Sample Feature Disabled

Sigma Rules

View Source
Summary
This detection rule aims to identify instances where the "Automatic Sample Submission" feature of Windows Defender has been disabled. This functionality is crucial for sending suspicious files and behaviors to Microsoft for further analysis and can significantly impact the efficacy of threat detection. Disabling this feature could indicate potential malicious activity aimed at evading detection. The rule is structured to monitor EventID 5007 from the Windows logs, specifically looking for changes in the registry setting that controls sample submission consent. The detection is triggered when the NewValue indicates that submission consent is set to 'disabled' (0x0). As such, any alterations to this setting warrant further investigation as they may reflect a more significant evasion attempt by a threat actor.
