What it detects

This rule detects changes to the Windows Defender antimalware platform configuration where SubmitSamplesConsent is set to 0x0. Disabling Automatic Sample Submission can reduce the availability of telemetry for malware analysis and hinder defensive feedback loops. The detection relies on windefend events indicating an antimalware configuration change and the specific updated setting value.
