On October 20, 2021 between 4:30pm UTC and 5:30pm UTC our suspicious activity monitoring generated unnecessary alerts in Malwarebytes Nebula and OneView. If you saw an increase in suspicious activity alerts during this timeframe, no action is required.
Symptoms
- A large increase in suspicious activity alerts during the noted timeframe.
Environments
- Malwarebytes Nebula
- Malwarebytes OneView
Cause
Malwarebytes releases updates with rules that run in silent mode so they do not trigger false positive alerts. The rules released today were not launched in silent mode, which generated the alerts seen in your admin console.
Resolution
No action is required. The rules have been moved into silent mode so we can adjust them to ensure they are accurate and valid.
