ThreatPost – The city of Johannesburg, South Africa, is refusing to pay a ransom of four Bitcoins to a hacker group who accessed the city’s network and stole sensitive data, threatening to release it if the ransom wasn’t paid.
It’s the second time in several months that the city has been hit with a cyberattack demanding ransom. In July, a ransomware attack on Johannesburg’s City Power, which is owned by the city itself, left some residents without electricity for days.
