Sony has told CVG that it is taking "necessary action" to protect PS3 from software piracy - following the release of new security-related Firmware last night.
Although the platform holder didn't directly admit that Firmware 3.42 is designed to block infamous hack PSJailbreak, early reports suggest it's left the programme redundant.
A Sony spokesperson told CVG this morning:
"Since this is an overall security related issue, we will not be providing further commentary with regards to this case; however, as we always have we will continue to take necessary actions from both hardware and software to protect the intellectual property of the content offered on the PS3 system."
Sony has succeeded in getting a PSJailbreak USB banned at retail in Australia.
