Microsoft said today that some of its customers' sensitive information was exposed by a misconfigured Microsoft server accessible over the Internet.

"This misconfiguration resulted in the potential for unauthenticated access to some business transaction data corresponding to interactions between Microsoft and prospective customers, such as the planning or potential implementation and provisioning of Microsoft services," the company revealed.

According to Microsoft, the exposed information includes names, email addresses, email content, company name, and phone numbers, as well as files linked to business between affected customers and Microsoft or an authorized Microsoft partner.

While Microsoft refrained from providing any additional details regarding this data leak, SOCRadar revealed in a blog post published today that the data was stored on misconfigured Azure Blob Storage.

"On September 24, 2022, SOCRadar's built-in Cloud Security Module detected a misconfigured Azure Blob Storage maintained by Microsoft containing sensitive data from a high-profile cloud provider," SOCRadar said.

SOCRadar's data leak search portal is named BlueBleed and it allows companies to find if their sensitive info was also exposed with the leaked data.
