The hackers behind the massive cyberattack on the US government and corporate networks have gained access to the source code and internal systems of Microsoft. This is reported by The Wall Street Journal with reference to the press service of the IT giant.

They were able to penetrate the internal networks of the IT giant by hacking its supplier - SolarWinds. Microsoft emphasized that customer data did not fall into the hands of hackers, they could not make changes to the source code

The company has confirmed that it has downloaded the software from its provider SolarWinds. This software has been infected with malicious code. Thus, cybercriminals gained access to Microsoft's internal networks.

“We found unusual activity on some internal accounts, and after checking, we found out that one account was used to view the source code in multiple repositories,” the corporation said.

Microsoft emphasized that attackers who got hold of the account could view the source code, but not change it. At the same time, the company did not specify exactly which products were affected by the hacker attack.

 “We found no evidence of access to manufacturing services or customer data, and no evidence that our systems were being used to attack others,” the company said.

In mid-December, US media reported that a cyberattack had been carried out on the country's government and private networks for months. The Ministry of Finance, the National Telecommunications Administration, and other departments fell under it. The media reported that Moscow was behind the APT29 hackers (also known as Cozy Bear). The accusation the Kremlin in a network attack on the United States denied.
