The new ransomware called WannaCry, started on May 12 2017, which encrypts files on the computers running Microsoft’s Windows operating systems and demands the payment up to $300 in the cryptocurrency bitcoin to receive a decryption key.

It also behaves like a worm which is potentially infecting computer and servers on the same network.

The ransomware WannaCry targets a Windows operating system flaw in older versions of the Windows OS that have not been patched and has not been updated.

The attack exploits a vulnerability in older Windows operating systems,:
Windows xp
Windows Server 2003
Windows 8
