How does it work?

This malware not just encrypts the files on a targeted system but it also encrypts the hard drive’s master file table (MFT). This renders the master boot record (MBR) useless and the system doesn’t boot.

After this, the malware reboots the affected system and displays a fake message. This enables it to secretly encrypt the whole system. It is being learned that the Petya ransomware has actually replaced the system’s MBR with custom malicious code which displays a ransom note. This leaves the device functionless. In exchange for the decryption code, a demand of $300 worth of bitcoins is made by the hacker.
