Yesterday, Sony issued a new firmware update with a new encryption key. It would require users to run firmware v3.56 to sign on, disabling the custom firmware that spoofs v3.55. However, Edge reports that within hours, hackers had unlocked the new update. Now another piece of custom firmware is expected to spoof v3.56 soon.
To be fair, this is Sony's first attempt at sealing the recent flood of hacks, and the company could improve its methods in the future. For the time being, though, Sony's promise to secure its system through firmware updates seems shaky.
