Security News > 2020 > May > Microsoft Investigating GitHub Account Hacking Claims
Microsoft says it's investigating claims that its GitHub account has been hacked, and while some say the leaked files appear to be legitimate, it's unlikely that they contain any sensitive information.
Data breach monitoring and prevention service Under the Breach reported on Thursday that a hacker claimed to have obtained 500 GB of source code from Microsoft's private GitHub repositories.
A post offering some of the files for free on a hacker forum claims that the data is 54 GB compressed and 500 GB uncompressed, but software engineer Rafael Rivera, who also confirmed that the files appear to be real, said there are only roughly 63 GB of files when uncompressed.
A Microsoft spokesperson told SecurityWeek that the company is aware of the claims and has launched an investigation, but did not provide any additional information.
Twitter user Nirmal Guru also says the leaked source code appears to be real, but points out that it's "Useless" as all private Microsoft repositories on GitHub are made public at some point.
