Security Event Logging Disabled via MiniNt Registry Key - Registry Set

Sigma Rules

View Source
Summary
This detection rule identifies when the 'MiniNt' registry key is added to the Windows registry under 'HKLM\System\CurrentControlSet\Control'. The presence of this key signals that the Windows Event Log service may be disabled, which stops logging security events following a reboot. This behavior aligns with tactics associated with adversaries attempting to evade detection by disabling important logging functionalities on compromised systems, as continuous and reliable logging is crucial for security monitoring and auditing. By monitoring any changes to this registry path, security teams can potentially take preemptive actions against attempts to disable event logging, thereby enhancing overall system security.
