Anonymity in Bitcoin has not only benefited innocent crypto users inasmuch that the same veil hiding the identity of the people behind transactions is also a boon for criminals. The City of Johannesburg said no to a group of cybercriminals who are demanding leaders cough up a crypto ransom in the amount of 4 Bitcoin worth approximately $37,471 in exchange for ‘captured’ data.
Johannesburg city council member Funzela Ngobeni said the hackers gained access to the city's computer systems and gave them until Monday to make the payment of four bitcoins, which is equivalent to 500,000 rands, according to the council. The officials are refusing to pay and the ultimatum date has now elapsed.
"The city will not concede to their demands for bitcoins, and we are confident that we will be able to restore systems to full functionality." - Ngobeni said in a statement.
The city hall of Johannesburg said that they themselves are able to restore all the hacked systems and are not going to go to the demands of hackers. It is reported that some systems have already been restored. In addition, authorities said they were able to determine the source of the attacks, but refused to provide details.
Also in summer, hackers attacked Johannesburg's main energy company. Then the attackers managed to get access to the database, the internal network, the web application and the official site, which is why all the work was stopped.
