Microsoft has admitted to mistakenly leaking 38 terabytes of private data belonging to its employees, including passwords, private keys and Teams messages. The leak took place in July 2020 and was uncovered earlier this year.

The leak was through the sharing of a misconfigured Blob storage bucket on the company's Azure cloud platform, while donating open-source AI learning models to a public GitHub repository, Microsoft said this week.
