Denuvo is a digital rights management system aimed at protecting digital media from piracy and reverse engineering.
The system uses unique methods to authenticate the game's code and the user, involving hardware identification checks that connect to a Denuvo server.
Denuvo employs various hardware and software integrity checks to prevent tampering, including the use of encrypted constants and virtual machine execution.
The technology integrates mechanisms such as CPUID instructions, KUSER_SHARED_DATA checks, and Process Environment Block (PEB) monitoring to validate hardware and software environments.
Denuvo makes use of sophisticated techniques like mixed-boolean-arithmetic for obfuscation and randomization, making it challenging to crack.
The protection system is designed to handle changes in hardware identification and prevent unauthorized access through a system of licensing files.
Cracking Denuvo is complex, involving techniques like hardware ID check patches and hypervisors, yet full restoration of binaries is rare.
Denuvo's efficiency in protecting games highlights its successful application even amidst attempts to bypass its security.
