We shall not pay the ransom, Johannesburg tells hackers

Coingeek – We shall not pay the ransom. This is the message that the city of Johannesburg in South Africa has for hackers who breached their systems. The hackers demanded 4 BTC, worth about $30,000, threatening to leak sensitive information if their demands were not met. They even gave the city a deadline. However, Joburg isn’t about to surrender to the crooks, despite admitting that some of its most crucial systems had been hit.
