Petya Ransomware Spreading Rapidly

It has not been so long that WannaCry had attacked too many Windows based PCs. Another ransomware like WannaCry which is called Petya is spreading rapidly now. It has infected so many computers in short period of time. Petya ransomware encrypts the hard drives master file and renders the master boot record. Petya replaces the computer's MBR with it's malicious code. Like WannaCry, it also demands 300$ woth of bitcoin to get the files back. Infected users shouldn't pay the ransom because the email address used by the attacker is suspended, so you cannot communicate with the attacker. Petya ransomware is exploiting SMBv1 EternalBlue Exploit, same as WannCry. If you're running Windows 10, your computer is not likely to be vulnerable to attack. You can prevent Petya ransomware by creating file named perfc in C:\Windows and marking it as Read Only. You can download this file and run it to do that for you.
