Petya is a nasty piece of ransomware and works very differently from any other ransomware malware. Unlike other traditional ransomware, Petya does not encrypt files on a targeted system one by one.
Instead, Petya reboots victims computers and encrypts the hard drive's master file table (MFT) and renders the master boot record (MBR) inoperable, restricting access to the full system by seizing information about file names, sizes, and location on the physical disk.
Petya ransomware replaces the computer's MBR with its own malicious code that displays the ransom note and leaves computers unable to boot.
Petya ransomware, another large-scale ransomware attack is making chaos worldwide, encrypting systems in companies, power supplies and banks
