The city of Atlanta, Georgia has been hit by a ransomware attack and data breach. While its critical infrastructure, systems and public services appear to be largely unaffected, the authorities are advising anyone who has conducted a recent financial transaction with the city to check that their financial and online systems have not been compromised. City employees have been instructed not to log on to their computers.
The ransom demand was made in bitcoins and the attackers may have utilised the SAMSAM virus, which allows them to encrypt parts of a disc.
It is not clear whether the attack is now under control or whether it remains a continuing threat. City officials are working with the US Secret Service, FBI and the Department of Homeland Security, plus swat teams from Microsoft and Cisco to assess the full extent of the incursion.
