What you need to know about wannacry ransomware

On Friday, May 12, a global cyberattack was launched using ransomware, a type of malicious software that encrypts the victim’s files and requires a ransom be paid to the hacker to unlock the files. The ransomware called WannaCrypt, or WannaCry, uses a Microsoft vulnerability that affects all versions of Windows prior to Windows 10.  

A security patch (MS17-010), addressing the vulnerability was released in March for all supported operating systems. A patch for unsupported versions (XP, server 2003) was issued on Friday, May 12.
