US military notifies 20,000 of data breach after cloud email leak

A misconfigured Microsoft government cloud email server used by the Defense Intelligence Agency exposed roughly three terabytes of sensitive but unclassified emails (including SOCOM-related communications and personnel/security-clearance questionnaires) to the public from Feb 3–20, 2023, impacting about 20,600 individuals; the exposure was discovered by a security researcher, reported to TechCrunch and U.S. officials, and the server was secured on Feb 20 after escalation.
