In the in-depth investigation of solarwinds incident, Microsoft found that some internal accounts were obtained by hackers, and visited part of the company's source code. Now, a hacker is selling the windows 10 source code for $600000, but he can't be sure of its authenticity.
Jake Williams, a security researcher at rendering infosec, reported the news, warning that the hackers appeared to be from shadow brokers, a well-known Russian hacking organization. But they may be to confuse the public and not really have access to these source codes.
Microsoft confirmed that hackers could view but not change the source code of some products, and said there was no evidence that the activity put the security of Microsoft Services or any customer data at risk. Microsoft said that checking the source code does not increase the risk, because the company does not rely on the confidentiality of the source code to ensure the security of its products.
