City Power in Johannesburg, South Africa, was left in the dark for a part of Thursday after an unknown ransomware variant knocked out its network, databases and applications. By Friday morning, City Power had restored power and most services for affected residents. The utility did not say if the attackers asked for ransom or if officials paid to restore service. Many of these localized ransomware incidents have in common is that the attackers are taking advantage of poorly secured IT systems and networks, says Richard Gold, head of security engineering at security firm Digital Shadows.”]
