After six months of work, DRM developer Maurice Heumann has successfully cracked Hogwarts Legacy's Denuvo DRM protection system. Rather than hacking it for illegal reasons, Heumann wanted to hack Hogwart's DRM for the sole purpose of learning its intricacies. As a result, the developer left plenty of the details of his work vague so as not to promote illegal cracking.
Heumann reveals in his blog post that Denuvo utilizes several different methods to ensure that Hogwarts Legacy is being run under appropriate (legal) conditions. First, the DRM creates a "fingerprint" of the game owner's system, and a Steam Ticket is used to prove game ownership. The Steam ticket is sent to the Steam servers to ensure the game was legitimately purchased. Heumann notes that he doesn't technically know what the Steam servers are doing but says this assumption should be accurate enough to understand how Denuvo works.
I spent the last 5 months reverse engineering Denuvo's protection in Hogwarts Legacy and finally managed to bypass it using more than 2000 hooks 😂One of the toughest challenges of my life. Here's my blog post about it:https://t.co/DLf6g5nv0nApril 1, 2024
