Hyperion (Byfron)

Hyperion is the anti-cheat built by Byfron Technologies, which Roblox acquired in 2022 and deployed with its 64-bit client in 2023. On Roblox it runs in user mode, compiled into the player client (packing, obfuscation, integrity and memory checks) rather than as a kernel driver, though Hyperion ships kernel components in some other games.

What it can and cannot see

On Roblox, Hyperion is not a kernel driver at all. It is compiled into the player client and works from inside it, with packing, obfuscation, and integrity and memory checks. It sees what happens within the client process on your machine, not the whole system the way a kernel anti-cheat would. (Byfron ships kernel components in some other games; this describes the Roblox deployment.)

The same boundary applies to every anti-cheat here. Anti-cheat that runs on your PC can examine what happens on that PC, to the depth its design allows. It cannot see a second computer, a capture device, or hardware placed between an input device and the port it plugs into. That is why the presence of an anti-cheat is not, on its own, proof of anything about a player, in either direction. Vera describes what runs; it does not decide what it means.
