If you were expecting a quiet Friday in terms of cyberattacks, this ain’t it. There are reports of a massive ransomware attack affecting computers on a global scale: in the UK, Spain, Russia, Ukraine, Japan, and Taiwan.
The ransomware variant that’s doing the damage is called WCry, also known as WannaCry or WanaCrypt0r. It has so far claimed some high-profile targets, including NHS hospitals in the UK, and telecom and banking companies in Spain.
Be calm and carry on, of course.
In the blog, we’ve been writing about ransomware over the last two years, and we have great educational resources to help you prevent or reduce the damage of an attack.
