The Medusa ransomware gang has leaked the source code for Microsoft Bing, Bing Maps, and Cortana online, and they have stated this on their website. "Most of the programmers show a deep interest in this breach just because it contains the source code for Bing, Bing Maps, and Cortana products of Microsoft. There are many digital signatures of Microsoft products in the leak. Many of them have not been withdrawn. The hackers have dropped this message on their website "Go ahead, and your software will have the same level of trust as the original Microsoft product,"
The message of the cybercriminals was published by Emsisoft Threat Analyst Brett Callow on his Twitter account. According to the specialist, the leak is about 12 GB and is part of the 37 GB stolen by the Lapsus group in 2022. Microsoft did not provide any comments on the leak, so the authenticity of the hackers' words has not been confirmed.
According to Callow, it is not clear if there is any connection between Medusa and Lapsus, but some aspects of the modus operandi (sacrifices, tools, etc.) do resemble Lapsus. This refers to an incident in March 2022 when Lapsus hackers claimed to have hacked into the internal Microsoft Azure DevOps environment and stole about 37 GB of information, that includes Bing and the Cortana internal private source code, as well as the projects of WebXT compliance engineering.
