Johannesburg, South Africa, again hit by ransomware attack

Johannesburg, South Africa’s largest city, was once again targeted by ransomware attacks in July, when some residents lost electric power to ransomware attacks. The hacker group, which calls itself Kill Hackers, demanded a ransom of 4 bitcoins after it infected the city’s internal network with ransomware and demanded to be transferred by 5 p.m. local time on October 28.


At current currency value, this is equivalent to $37,000. Hackers say they will upload city government data online if they refuse to pay the ransom.

In the ransomware notice, the hackers said they had hacked into city government servers, implanted dozens of backdoors and controlled everything, including all passwords and sensitive data such as financial and demographic information.


Municipalities shut down all IT infrastructure, including websites, payment portals, and other electronic services. The city government’s official Twitter account confirmed the intrusion.
