PS4 Jailbreak Exploit by Chaitin Tech Echoes via SpecterDev

Many may recall the PS4 Firmware 4.01 Jailbreak by Chaitin Tech, their ROP Tool and the addition of Kaslr Support last year.

Following his PS4 4.0x WebKit Userland Exploit Documentation, JailbreakMe PS4 3.5x / 3.70 / 4.0x Exploit Ports and continuing research PlayStation 4 developer SpecterDev shared a tweet earlier today echoing Chaitin Tech's PS4 kernel exploit on 4.05 that was disclosed to Sony and patched in 4.06 official Firmware this past November.

The news comes after qwertyoruiopz's PS4 4.50 Kernel R/W Access announcement, PS4 4.5x Pwnage and confirmation of PS4 4.55 Dumped.

While @SpecterDev already stated he can't release it and as a result decided to remove the tweet, at least PS4 Developers who have been collaborating and examining it can rest assured that Chaitin Tech and Sony aren't the only ones privy now... here's to hoping someone else will also run across it and decide to share it with the scene.

From the PSXHAX Shoutbox for those following:

• B7U3 C50SS: Status..
• B7U3 C50SS: is gone..
• SpecterDev: yea B7 I removed my status because I felt it rubbed people the wrong way
• SpecterDev: I didn't want to make a big deal out of it because I can't release it anyway so I decided to delete it
• SpecterDev: 4.05 and below, the one chaitentech disclosed
• SpecterDev: to Sony that is
• oneman123: SpecterDev: shae SceEapCore.elf

He's released a lot, for example the 3.55 PS4 Playground and more recently all the JailbreakMe PS4 3.5x / 3.70 / 4.0x Exploit Ports.

PS4 scene devs are more concerned with things that may lead to backups as they don't want to be held liable for those who may misuse them, such as kernel exploits that could open the door to running retail game backups... if they are licensed developers as their day job it would jeopardize their careers too.

Sooner or later the pirates win though... they always do.

Yes !!! I promise you, when I'll see something REAL, I'll change my user

But until that day, when I read : I've a working jailbreak, but I don't public it, for me It's a GREAT FAKE !

 

[PSXHAX]

Sounds like a plan to me then also

 

[lobimagobi]

Still useless or fake tweets.

We shouldn't even write news about these pathetic "hackers" so they will get tired of announcing fake exploits and wait for real ones.

Many don't seem grateful or even aware of everything established PlayStation 4 developers like SpecterDev and Qwertyoruiop have contributed thus far in the PS4 scene on their own time for free, yet it's repeated throughout the articles and discussion posts.

Apparently unless a way to play game backups and homebrew on the PS4 is handed over on a silver platter all of the other steps that led up to such accomplishments are meaningless to some people... but not to everyone, myself included.
