Cryptocurrency ransomware of different flavors has been around practically as long as cryptocurrencies themselves. And now the city of Atlanta, US has come under the attack.

The governmental computer system has been infected by the ransomware virus early in Thursday, and this has caused a massive disruption in several departments. In particular the bill payments and court information services has been affected. Later in the morning several city employees found a ransom letter on their computers with demands for $51,000 in Bitcoin.

In the afternoon of the same day officials held a press-conference, but were unable to provide any particular information about the attack since the investigation was just commenced and in the early stages. The question whether or not they were going to pay the ransom were also left unanswered.

Atlanta is one the major economics hubs in the Southern US with several large international companies and the world's busiest airport located in the city. Apparently, the city officials have no qualms about going for all the available help in such a high-resonance case, hence the US Department of Homeland Security, the FBI and even the Secret Service authorities are now on the ground.

Of course, there is little chance of systems being unlocked even if the ransom is paid, the security experts say. So, the city is probably in for a long road to full recovery of its computer facilities. The officials have even started making plans in preparation for long and tedious recovery process.
