Yesterday, some residents of Johannesburg, the largest city in South Africa, were left without electricity after the city's power company got attacked by a ransomware virus. City Power, the company responsible for powering South Africa's financial capital Johannesburg, confirmed Thursday on Twitter that it had been hit by a Ransomware virus that had encrypted all of its databases, applications, and network.

Hackers Suspected of Causing Second Power Outage in Ukraine

Dec 21, 2016
The same group of hackers that caused the power outage across several regions in Ukraine last Christmas holidays might have once again shut down power supply in northern Ukraine during the weekend. According to Ukrainian energy provider Ukrenergo, a cyber attack on Kyiv's power grid may have caused the power outages in the country on Saturday, December 17, near midnight. The blackout affected the northern part of Kiev, the country's capital, and surrounding areas, Ukrenergo Director Vsevolod Kovalchuk explained in a post on Facebook. Shortly after the incident, Ukrenergo engineers switched to manual mode and started restoring power in approximately 30 minutes in an effort to deal with the cyber attack. Power was fully restored after just an hour and fifteen minutes of the blackout.

IT leaders know the drill—regulators and cyber insurers demand regular network penetration testing to keep the bad guys out. But here's the thing: hackers don't wait around for compliance schedules.

Compliance-focused testing can catch vulnerabilities that exist at the exact time of testing, but it's not enough to stay ahead of attackers in a meaningful way. Why More Frequent Testing Makes Sense When companies test more often, they're not just checking a box for compliance—they're actually protecting their networks. The Kaseya survey also points out that the top drivers for network penetration testing are: Cybersecurity Control and Validation (34%) – ensuring the security controls work and vulnerabilities are minimized.
