I doubt that anybody still want to hack the Sony Playstation 3 at this stage: all its defences have been broken down. Still if anybody is interested, it seems by blog post on HTML for old geeks manages to crash the PS3, hard: the whole console freezes, and the only way to unblock it is to forcefully shut it down, only to be greeted at boot time with the message that the system was not shut-down properly, that a file-system check is needed. If feels a lot like Mac OS 20 years ago. I don’t know if this could be exploited, but given the general health of Sony corporation, I doubt we will see an updated firmware soon.
