Microsoft’s cloud services had recently been hit with a security flaw that had the potential to expose thousands of businesses before it was caught and fixed. The vulnerability was discovered by Wiz, the Alphabet-owned cybersecurity company known for identifying major cloud security issues. The company said the flaw existed in Azure Cosmos DB, a core Microsoft cloud database service that is widely used by businesses across industries. Although Microsoft did not disclose how many users could have been at risk, Azure Cosmos DB is considered one of the key building blocks of its cloud platform. Karl Fosaaen, Senior Vice President at NetSPI, noted that Cosmos DB frequently stores sensitive information, making any security flaw a major concern.
