There's a new PlayStation 4 exploit in town--PS4 scene developers have released pOOBs4, a new kernel exploit that affects consoles on firmware 9.0.0. According to the pOOBs4 GitHub page, this exploit functions a little differently from previous PS4 jailbreak methods; you'll need a dedicated USB drive with the jailbreak software, which you'll insert into the system at a specific time during the process. The hack can also work on the PlayStation 5, claims the team, but triggering it isn't possible yet, and they recommend that users don't try to mess with their PS5 consoles until more information is available on how it affects that system. Currently, any PS4 that is on OFW 9.0.0 or below is exploitable using this method.

In this project you will find an implementation that tries to make use of a filesystem bug for the Playstation 4 on firmware 9.00. The bug was found while diffing the 9.00 and 9.03 kernels. It will require a drive with a modified exfat filesystem. Successfully triggering it will allow you to run arbitrary code as kernel, to allow jailbreaking and kernel-level modifications to the system. will launch the usual payload launcher (on port 9020).

The instructions and jailbreak file itself can be downloaded from the source below. Useful homebrew tools Mira and GoldHEN have also been updated to work with this new version.

• You need to insert the USB when the alert pops up, then let it sit there for a bit until the ps4 storage notifications shows up.
• Unplug the USB before a (re)boot cycle or you'll risk corrupting the kernel heap at boot.
• The browser might tempt you into closing the page prematurely, don't.
• The loading circle might freeze while the webkit exploit is triggering, this means nothing.
• This bug works on certain PS5 firmwares, however there's no known strategy for exploiting it at the moment. Using this bug against the PS5 blind wouldn't be advised.

why not just keep it private until PS4 is EOL?

While I can agree with this with regards to the PS5, in terms of the PS4 This exploit is not possible from 9.03 so no need for them to wait longer in the PS4's lifecycle.

This is so good

The article says it works on firmware 9.00 and below. Does it also work in old exploitable firmware? or higher than 7.55?

Let me check my crystal ball.

We're just gonna have to wait for details I'm afraid.

i just updated to 9.03 yesterday after turning my PS4 on for the first time in a year

You got fucked by Keanu.

This is fantastic... now I just need to get a PS4.

Don't know what purpose that would serve considering the following:
"The bug was found while diffing the 9.00 and 9.03 kernels" - article quote
In other words, the exploit was already fixed.

Great news for everyone that's been waiting patiently!
Personally, I'm happy to keep my system up to date just for online features... but IF there's ever an EOL exploit down the line, I'll certainly give it a shot.

dang it, i gotta work today but this is awesome!!!

I wonder if more PS3 exploits will be found considering tbe PS3 is basically dead?

I wouldn't be at all surprised... especially considering how many hacks for the PS1 and PS2 were discovered over the last couple of years - many, many years after those consoles were current.

PS5 = meh
CFW PS5 = hell yeah!

 

[SilverWah]

Aww shit my Pro is on 9.03.
Bummer.

wait is it not? It's successor came out a year ago and because it's a blu-ray player it's gonna get updates for a while just like how the PS3 still gets updates so if you go by updates it won't be EOL for a very long time

The PS4 still gets games released for it, though. I guess that's really when we call it end of life: as soon as it no longer gets new releases regularly.

If I recall correctly wouldn´t this kind of access allow developing more permanent-ish CFW solutions for PS4?
