Johannesburg, South Africa, is an alpha city on a booming continent—a financial powerhouse and one of the most important cities in the world. It’s also a repeat victim of hackers who at least twice in three months have shut down important city services and networks.
The new attack: On Thursday night, the city of Johannesburg shut down its website, e-services, and billing as a result of a “network breach which resulted in unauthorized access to [city government] information systems.”
Local media reported that hackers demanded ransom, but city spokesman Nthatisi Modingoane went on television on Friday to assert that there was no “formal demand for ransom.”
