EuroGamer’s Richard Leadbetter explained, “The release of the new custom firmware – and the LV0 decryption keys in particular – poses serious issues. While Sony will almost certainly change the PSN passphrase once again in the upcoming 4.30 update, 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.”
Chinese hacking group BlueDiskCFW highlighted this particular issue, and they do have plans to make money by selling the custom firmware. Of course, it has been disputed that the BlueDisk team did not make this discovery, but just want the publicity and perhaps saw an opportunity to make quick cash off the masses.
