Atlanta’s city hall has given the all-clear for workers to turn systems back on following a ransomware attack that caused issues with certain scheduling and procurement processes.  The Atlanta ransomware attack began early in the morning on March 22 and the FBI, Department of Homeland Security, Microsoft and Cisco were brought in early on to investigate and help the city remediate the issues.

Today, the City of Atlanta is advising its employees to turn on computers and printers for the first time since the March 22 cyberattack,” wrote Anne Torres, director of the Mayor’s Office of Communications, and Nikki Forman, press secretary for the city, in the statement. “It is expected that some computers will operate as usual and employees will return to normal use. It is also expected that some computers may be affected or affected [sic] in some way and employees will continue using manual or alternative processes. This is part of the City’s ongoing assessment as part of the restoration and recovery process.”
