The Justice Department revealed that its email system had been affected by the SolarWinds cyberattack that was suspected to have been carried out by the Russians, though it emphasized that the access appeared to be limited and that there was no evidence of classified information being stolen.

DOJ spokesman Marc Raimondi said on Wednesday that the Justice Department’s Office of the Chief Information Officer learned of “previously unknown malicious activity linked to the global SolarWinds incident” on Christmas Eve and that “this activity involved access to the Department’s Microsoft O365 email environment.”
