| There were two versions of the PS3: The original model and a slimmed down version released after a few years. the timeline was something like this: - Sony released the original PS3 with Linux running under a hypervisor that locked certain things (e.g. 3D rendering and their DRM) - Sony released the PS3 slim without Linux. They claimed they didn't have the resources to make Linux run on it. (We later figured out all that was required were a few incredibly simple kernel patches) - geohot found a somewhat unstable hardware glitch that, with some luck and a few tries, could escalate to hypervisor mode and enable e.g. 3D rendering from Linux. Their DRM was still untouched at this point and no one really cared. - Sony released an update for the old PS3 models to disable Linux as well citing "security concerns" After that more people started looking into the PS3 and marcan, me and others at fail0verflow eventually figured out their security wasn't all that great. It was actually so bad that we could calculate their private keys. Then they sued us for that but that's another story. |
