It said at least 80% of employees at the US attorneys' offices in the Eastern, Northern, Southern and Western Districts of New York had seen their accounts breached, with other districts "impacted to a lesser degree." The DOJ said at least one employee account was accessed at 27 offices from the West Coast to the East. "To encourage transparency and strengthen homeland resilience, today we are providing additional details about the SolarWinds intrusion in December 2020." "The Department of Justice understands that when victims make information public about the nature and scope of computer intrusions they suffered, others can use that information to prepare themselves for the next threat," the DOJ said in a statement Friday.

The department revealed in January that its Microsoft Office 365 email environment had been breached, but it hadn't provided the information about the US attorneys. As part of the SolarWinds hack, according to the agency, attackers accessed accounts at nearly 30 US Attorneys' offices, including offices in Washington, DC New York and California. Hackers hit the offices of top US federal prosecutors nationwide last December, breaking in to email accounts, the Department of Justice said Friday. Hackers had access to email accounts for more than six months, the DOJ says.
