Sharing chatgpt answer as I was curious myself

Denuvo differs from older DRM by continuously protecting the game’s code instead of just checking ownership once. Traditional systems like Steam or SecuROM perform a one-time validation, but Denuvo embeds encryption, obfuscation, and constant runtime checks directly into the executable, making it much harder to analyze or modify. The recent bypass described by Tom’s Hardware didn’t actually “crack” Denuvo in the traditional sense. Instead, it used a hypervisor, a low-level virtualization layer, to sit between the game and the operating system and feed Denuvo fake “valid” responses so it believes everything is legitimate. This avoids removing the protection entirely and instead tricks it. The tradeoff is that the method requires disabling core Windows security features, which creates serious system-level risks and is why even some in the piracy community consider it unsafe.
