The city of Augusta in Georgia, U.S., has confirmed that the most recent IT system outage was caused by unauthorized access to its network.

The administration has not disclosed the nature of the cyberattack but the BlackByte ransomware gang has published the City of Augusta as one of its victims.

BlackByte has posted the City of Augusta on its extortion site, claiming responsibility for the recent attack.
