Almost as a direct reply to a US judge’s pardoning Sony of responsibility for the 2011 hacking of the PlayStation Network, Chinese hacking group The Three Tuskateers released BlueDiskCFW, a custom firmware that would circumvent security, both current and future.
Sony had fixed the exploits used by Fail0verflow in the 3.60 firmware update, but with BlueDiskCFW, compromised consoles can log into PSN with LV0 decryption keys to bypass future security updates.
US District Judge Anthony Battaglia claimed that Sony was free of responsibility from the PlayStation Network intrusion because the service was free, ignoring the fact that user accounts and data info was compromised.
