Abstract
This is the new release of OpenPetya: v2.0.0
What Is New
OpenPetya now supports Windows UEFI. In v1.0.0, I implemented the MFT encryption algorithm. In this version, however, I chose not to implement it for UEFI out of concern that it might be abused to damage modern Windows operating systems.
