Microsoft has admitted to losing more than two weeks of security logs for some of its cloud products, which could raise concerning security risks.

Microsoft reportedly reported the issue to users, saying the loss was not due to a security incident or attack, but rather a software flaw.

“A bug in one of Microsoft’s internal monitoring agents caused some agents to malfunction when uploading log data to our internal logging platform,” Microsoft said. The malfunction occurred between September 2 and 19.

Logs are important because they help IT teams track possible intrusions and other cyberattacks. Therefore, not having this information for more than two weeks puts users at risk.

According to reports, the malfunction affected a few products: Microsoft Entra, Sentinel, Defender for Cloud and Purview. Affected customers “may have experienced potential vulnerabilities in security-related logs or events, possibly impacting customers’ ability to analyze data, detect threats, or generate security alerts,” the company said in the statement. notification.

TechCrunch contacted John Sheehan, vice president of Microsoft, who did not share further details about the bug, but said that Microsoft had fixed it: “We mitigated the issue by rolling back a service change. We have communicated with all affected customers and will provide assistance if necessary,” he told the publication.
