Cosmos DB Now Chaos DB
Microsoft warned thousands of its cloud computing customers, including some of the world’s largest companies, that intruders could have the ability to read, change or even delete their main databases.
The vulnerability is in Microsoft Azure’s flagship Cosmos database. A research team at security company Wiz discovered it was able to access keys that control access to databases held by thousands of companies.
Microsoft cannot change those keys by itself, it emailed the customers telling them to create new ones. Microsoft agreed to pay Wiz $40,000 for finding the flaw and reporting it.
The disclosure comes after months of bad security news for Microsoft. The company was breached by the same suspected Russian government hackers that infiltrated SolarWinds, who stole Microsoft source code here.
