Monitoring of the Windows Security event channel identified failed attempts to perform a privileged operation during a series of driver changes and updates.

The events involved the Windows privilege SeLoadDriverPrivilege and were observed on two different devices.

Event Location

Location: EventChannel

Channel: Security

The detected events originated from the Windows Security event channel and were related to privileged operations performed on the affected devices.

Cause of the Events

The events were generated by failed attempts to perform a privileged operation using SeLoadDriverPrivilege.

The failures occurred during multiple driver changes and updates on two separate devices.

The driver maintenance activity therefore provided the operational context for the privileged-operation failures observed in the security events.

Why the Activity Was Detected

Repeated failed privileged operations can create a noticeable change in security event activity.

In this case, several related events were generated during driver changes and updates, creating the pattern identified by monitoring.

The supplied information links the events to the driver maintenance activity rather than to a confirmed malicious operation.

Investigation Context

The relevant investigation context is the relationship between the failed privileged operations and the driver changes occurring on the two devices.

Reviewing the events together makes it possible to identify that the SeLoadDriverPrivilege failures occurred during multiple driver changes and updates.

Conclusion

The anomaly in the Windows Security event channel was caused by failed attempts to perform a privileged operation involving SeLoadDriverPrivilege.

The activity occurred during multiple driver changes and updates on two different devices, providing the context needed to explain the detected security events.
