This incident was first reported by Business Insider earlier in October but many details about this notification have not been exposed. Also, the security researcher Kevin Beaumont observed that these notifications which Microsoft sends about the incident, are probably sent just for those affected companies and maybe they are accessible to just a few users who have tenant admin rights. And that explains why this notification has not been publicly exposed before.
According to Bussiness Insider about cybersecurity news, the products that were affected by the Microsoft security issue are Microsoft Entra, Sentinel, Defender for Cloud, and Purview. The notification stated that all the affected customers and products “may have experienced potential gaps in security-related logs or events, possibly affecting customers’ ability to analyze data, detect threats, or generate security alerts,”.
Because Microsoft didn’t want to answer some specific questions about this Microsoft security problem, a Microsoft executive confirmed for TechCrunch that this cybersecurity issue was generated by an “operational bug within our internal monitoring agent.”
Also, the Microsoft corporate vice president, John Sheeran said “We have mitigated the issue by rolling back a service change. We have communicated to all impacted customers and will provide support as needed,”.
