The Russian hackers behind the massive SolarWinds cyberespionage campaign broke into the email accounts of some of the most prominent federal prosecutors’ offices around the country last year, the Justice Department said.
The department said 80% of Microsoft email accounts used by employees in the four U.S. attorney offices in New York were breached. All told, the Justice Department said 27 U.S. attorney offices had at least one employee’s email account compromised during the hacking campaign.
The Justice Department said in a statement Friday that it believes the accounts were compromised from May 7 to Dec. 27, 2020. Such a timeframe is notable because the SolarWinds campaign, which infiltrated dozens of private-sector companies and think tanks as well as at least nine U.S. government agencies, was first discovered and publicized in mid-December.
