According to Business Day, the attack comes after a group called Shadow Kill Hackers sent the City a ransom note demanding payment in Bitcoin. Otherwise, the hackers said they will release the information stolen.
“All your servers and data have been hacked. We have dozens of back doors inside your city. We have control of everything in your city. We also compromised all passwords and sensitive data such as finance and personal population information,” the hackers ransom note said, according to Business Day.
As a result of the shutdown, customers are not able to access e-services and the City said they will update citizens on a four hourly basis.
The hackers have allegedly set a deadline for the City to pay the 4.0 Bitcoin (around R435,000) for the 28 October at 5pm.
