Hackers who accessed government networks through SolarWinds software may have accessed about 3% of Justice Department email accounts, but there is no evidence that they accessed classified systems, a DOJ spokesman said in one Declaration on Wednesday.

The DOJ office of the chief information officer reportedly learned that agents had accessed the department's Microsoft Office 365 email environment from the hack on Christmas Eve.

"As part of the ongoing technical analysis, the department has determined that the activity is a serious incident within the meaning of federal information security modernization law and is taking the steps consistent with that finding," the spokesman said. "The department will continue to notify relevant federal agencies, Congress and the public as warranted."

On Tuesday, US intelligence agencies said the Russians were likely behind the breach, which affected several government departments. Microsoft was also a victim of the hack, Reuters reported in December.
