Microsoft disclosed today a security breach that took place in December 2019.

In a blog post today, the OS maker said that an internal customer support database that was storing anonymized user analytics was accidentally exposed online without proper protections between December 5 and December 31.

The database was spotted and reported to Microsoft by Bob Diachenko, a security researcher with Security Discovery.

The leaky customer support database consisted of a cluster of five Elasticsearch servers, a technology used to simplify search operations, Diachenko told ZDNet today. All five servers stored the same data, appearing to be mirrors of each other.

Diachenko said Microsoft secured the exposed database on the same day he reported the issue to the OS maker, despite being New Year's Eve.
