Consequently, the city has shut down its website and suspended all e-services as a ‘precautionary measure’. At the time of writing the city’s website was still inaccessible.
Per The Times, the group behind the cyber-attack is an outfit known as Shadow Kill Hackers. The group is demanding 4 Bitcoin – nearly $30,000 at the current Bitcoin price – by the close of business on October 28.
In their ransom note received by several employees of the city, Shadow Kill Hackers claimed to have obtained valuable and confidential data from the city:
“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.”
Failure to pay the Bitcoin ransom, the hackers have warned, will see the sensitive data released publicly.
Some of the e-services that will be affected by the shutdown include online billing services. Internet-based customer care services have also been suspended. An investigation into the Bitcoin ransomware attack has already been launched and is expected to take 24 hours.
