Microsoft investigating alleged Lapsus$ hack of Azure DevOps source code repositories


Microsoft says it is looking into claims that the Lapsus$ data extortion hacking group gained access to its internal Azure DevOps source code repositories and stole data.

The company told BleepingComputer that it was aware of the claims made by the group and was in the process of investigating those claims.

On Sunday, the Lapsus$ gang shared on its Telegram channel a screenshot of what appeared to be data acquired from an official developer account for Azure, Microsoft’s cloud computing business.

The operatives claimed to have gained access to an Azure repository that contained the source code for Cortana as well as other Bing projects.

Lapsus$ said it accessed the repositories by hacking an Azure DevOps server.

An administrator of the Telegram channel later deleted the screenshots and posted the message: “Deleted for now will repost later”.

However, the group left the initials of logged-in user, “IS,” in the screenshot, potentially enabling Microsoft to identify the hacked account.

Microsoft has previously said that a source code leak does not increase the security risk associated with its products.

The company’s security strategy already makes the assumption that bad actors have…
