Petya Ransomware Goes Low Level
The new Petya ransomware seems to have been built with speed in mind, as to expedite the encryption process. While traditional ransomware encrypts files one by one, Petya encrypts the location containing all information about disk files, such as size, permissions, and data content, essentially preventing users from accessing all their data.
Bitdefender was able to analyze the Petya ransomware and offer potential victims a tool that intercepts the encryption process and offers the decryption key, free of charge. Most importantly, the tool needs to be installed prior to being infected – not afterwards – in order to perform its function correctly.
