A very interesting development has taken place around the PlayStation 3 with a theoretically unstoppable hack.
The PlayStation 3 has been around since 2006, and since then, hackers have been trying to have their way with it. The system has proven to be very difficult to crack, though not completely impossible.
Sony released a major firmware update for the PS3 in 2011, it was update 3.60. That firmware update patched many of the wholes hackers were using, and prevented modded and hacked consoles from connecting to the online PlayStation Network. Up to now, the only work-around, was to not update past the firmware version 3.55.
Today however, the block keeping hacked consoles away from the network has now been surpassed with custom firmware. Simultaneously, the LV0 decryption keys for the PS3 have been dispersed through the internetz. According to Eurogamer:
The reveal of the LV0 key basically means that any system update released by Sony going forward can be decrypted with little or no effort whatsoever. Options Sony has in battling this leak are limited – every PS3 out there needs to be able to decrypt any firmware download package in order for the console to be updated (a 2006 launch PS3 can still update directly to the latest software). The release of the LV0 key allows for that to be achieved on PC, with the CoreOS and XMB files then re-encrypted using the existing 3.55 keys in order to be run on hacked consoles.
In simpler words: having access to the key means that a PC can now pretend to be a PS3. It can connect to the network, download information (games, files) and then produce games and files that can be read in physical format by modified PS3 consoles. As it stands, Sony will most likely be un capable of stopping this work around.
