Long ago we saw the Original PS4 Jailbreak for 1.76 FW via BadIRET Exploitation (Github Articles), and following his recent FreeDVDBoot PS2 DVD Player Exploit PlayStation 4 developer @CTurt shared via Twitter thoughts on FreeDVDBoot for PS3 / PS4 after discovering his FreeDVDBoot PREBUILT ISOs (GIT / Blog) also crash the PS4 in a video demonstration from V3dita BR on YouTube... meaning it may be vulnerable to the same bug, although he favors Blu-ray BD-J Attacks due to ASLR in later Firmware versions. šŸ¤©

Previously we've seen PS4 BD-J (Blu-ray Java) Homebrew, some PS4 BD-J (Blu-ray Java) Homebrew Answers, Ukko's Journey Blu-Play Game, Loading PS4 Payloads via Blu-ray (Server-less Option) BD-J, The UFO Game! Blu-Play Game and a Blu-Play DOOM I Port / Homebrew Games with C / C++ with further details on the PlayStation Blu-ray Disc Drive Security and Hacking PS4 / PS3 Blu-ray Drives via the 36c3 Livestream.

From @CTurt via Twitter in the Tweets below, to quote:
  • Regarding PS3/4, Blueray BD-J is what I'd attack. You can run arbitrary Java code by-design and can some native methods with controlled arguments which could be pretty nice attack surface. ASLR can be defeated in this scenario with some info leak bug, like in WebKit scenario.

  • As you say, exploiting DVD player on PS4 is probably impractical on later firmwares with ASLR (so I'd aim for Blu-ray instead), but apparently my DVDs crash PS4 so it might be vulnerable to the exact same bug lol
And from @theorywrong via Twitter from the Tweet below:
  • Probably vulnerable, but it's Userland with some more auth. And you need to deal with ASLR and It's not easy.

let's say it was passed on it will still be traced back to that dev and they'll still get sued regardless if they themselves released or not even if someone say honestly hacked the dev pulled the files and leaked em that way they could still sue for lack of computer security, given how good these devs are of hacking you'd think they'd be good enough in cybersecurity not get hacked themselves

Writing an article about security isn't what Sony is worried about its the use of circumvention and when it's done. As this attack still works on firmware 7.01+ as there is no way to patch it without hw upgrades

And Sony won't wanna do new hw upgrades when there ps5 will be out in a few months it's pointless to do from there standpoint but it will be patched on ps5 from working

ps3 ode is long dead but its legacy live on until Hen firmware were introduced, if we back to this method it is like a waste since everybody here already working with hen kex method, and it is pain to download all of 12tb of ps4 ODE game all over again

@mukasange there is no room for ode as it works as if the game is playing from disc not hard drive and the ps4 games are installed on your system not running from a disc. That's how ode worked in the old days but even they have some advantages as well

@godfist no you can't play latest ps4 games on hen the games exe needs to be for fw 5.05 so a game with 6.20 would kick the security check for your fw and ask you to update your firmware
