WanaCry is a ransomeware cyber-attack targeting the Microsoft Windows operating system. It was launched on May 12th, 2017. This unprecedented malware attack began sweeping the globe late last week, and security researchers estimated that nearly 57,000 computers in more than 150 countries were infected by the end of the day on Friday. While the spread of this terrifying ransomware was slowed on Saturday, it was hardly stopped. As of Monday morning, more than 200,000 systems around the world are believed to have been infected.
WannaCry is far and away the most severe malware attack so far in 2017, and the spread of this troubling ransomware is far from over.
Victims of WanaCry would see a terifying screen on their Windows System telling the that their files has been encrypted. The attackers through that screen requested a ransome of about $300 or $300 worth of Bitcoin to a specified bitcoin address.
At the left hand side of the window is a countdown threatening to delete victims encrypted files if payment has not been confirmed.
Currenly, most Antivirum companies such as AVG claim to protect people form WanaCry attack.
