ATLANTA — City employees were asked to stay off their computers Friday just one day after a massive cyber-attack against the City of Atlanta.
Employees at Atlanta City Hall were handed instructions as they came through the front doors Friday.
Channel 2 Investigative Reporter Aaron Diamant obtained a copy of the flyer that requested employees not turn on computers or log onto their workstations.
Friday’s action comes as city officials are struggling to determine how much sensitive information may have been compromised in a Thursday cyber-attack.
The city has also received demands that it pay a ransom of $50,000, according to Mayor Keisha Lance Bottoms.
Bottoms kicked off a Friday news conference by assuring the public that investigators haven't found any evidence that sensitive customer, resident or employee information was compromised.
Bottoms said federal investigators will advise her on the best course of action.
"This is a marathon, not a sprint," Bottoms said.
The FBI and the Department of Homeland Security are working with city officials to identify the source of the attack.
Hartsfield-Jackson Atlanta International Airport took down the Wi-Fi at the world's busiest airport after the cyber-attack.
The Atlanta airport’s website said security wait times and flight information may not be accurate.
Information from The Atlanta Journal-Constitution was used in this report.
