DeKalb County government operations and residents are not impacted by the cyberattack on the city of Atlanta, a DeKalb official said.

Atlanta reportedly received a ransom note demanding $50,000 on Thursday. Many of Atlanta's online systems went down, and city employees were told Friday not to turn on their computers.

DeKalb provides “frequent employee updates on security risks and reminders on how to exercise caution when computing,” John Matelski, DeKalb’s chief innovation and information officer, said in a statement.

DeKalb security systems block millions of attempts to introduce malware through email and an average of 1,000 non-email targeted attempts per day, spokesman Quinn Hudson said in an email.

“Thankfully, DeKalb County’s investments in people and systems have enabled us to avoid any major impacts of this nature,” Hudson said.

The county has 6,100 employees.
