PS3 3.56 firmware cracks but with tough new limits
Sony's 3.56 update for the PS3 has already been jailbroken on a basic level. In an update, Youness Alaoui said he had successfully unpacked the new firmware, making it possible to modify the code and get at its signing keys. Sony attempted to take down a public posting of the code with a DMCA request but has since been thwarted with a follow-up posting; the company is unlikely to fully stop access.
An actual jailbreak update isn't expected soon. Unlike 3.55 and earlier, where the main key was static and largely unprotected, the new key has been given random number encryption that prevents a predictable hack. It's unclear if this will genuinely stop hacks since teams like fail0verflow developed what they claimed was an unstoppable crack that would let hobbyists deconstruct any firmware within hours or days.
Sony has been trying to use legal pressure to silence the hacks, including a DMCA lawsuit and restraining order, but the gestures haven't prevented the techniques from spreading. The company has further faced an official response as it might be violating marketing laws. Its decision to remove alternate OS support while claiming an upgrade has been attacked by Norway's government for being dishonest. [via Edge]
