After teasing the exploit recently on Discord, SpecterDev has officially released his kernel exploit for PS4 firmware version 4.05.

Official announcement

Hope everyone had a Merry Christmas! Here's the 4.05 kernel exploit, fully implemented. Enjoy! Write-up coming soon! https://t.co/MQR0lzCu9Y

— Specter (@SpecterDev) December 27, 2017

Code:
https://github.com/Cryptogenic/PS4-4.05-Kernel-Exploit

TLDNR (From GitHub):

In this project you will find a full implementation of the "namedobj" kernel exploit for the PlayStation 4 on 4.05. It will allow you to run arbitrary code as kernel, to allow jailbreaking and kernel-level modifications to the system. This release however, does not contain any code related to defeating anti-piracy mechanisms or running homebrew. This exploit does include a loader that listens for payloads on port 9020 and will execute them upon receival.

In case you want to get a PS4 <=4.05

UPDATE:

after @SpecterDev released his exploit, i'll prepare stuff within a couple of days, someone need to backport it from 4.55 to 4.05, not hard to do. not sure if it will be a write-up or just snippets of code, let's see

That link doesn't point to anything.

It redirects me to my own uploaded videos edit page.

no worries give it time or try from my channel tis working for me sir

whoops good looking out fixed link my bad!

I make a big mistake and deleted my psn profile (i didn't want it associated with hacks and had no plans to go on psn with my jailbroken ps4). This made things harder for me as I did not realize this would break web browser. In hindsight this was a good thing. This is experience other user will have with new ps4 out the box. I hope this helps others....

thanks for video, my secondary ps4 is waiting in box and i had no idea about web browser...

yeah i found out the hard way many tears...but i got it sorted!

 

[Thelonewolf88]

What? Rly? How? We can do that on ps3, and we have the ps4 kernel exploit.

Seriously man, go do some reasearch. The PS3 cannot be compared to the PS4's security and just because a PS4 kernel exploit is released does not make it the same, as it's predecessor.

so far I tried to install the web browser patch.bin command seems to load but still no joy. I am also unable to install pkg. Perhaps my pathing?

If anyone would like to use this and doesn't want to host the files themselves you can find the exploit files on http://redthetrainer.com/ps4/

No, not yet. They are working on it in 5 days or so. Dont bother to install pkg for now.

Can we host the exploit in a smartphone to avoid going online?

There are various apps on android that you can use to host files, however iirc you still need to connect online to access local network files.

In that case you might as well use the page I hosted instead of going through all that trouble

So do you have to do the jailbreak each time you turn off your PS4 like the browser hack for the Wii-U?

 

[ploggy]

I think that's exactly what its going to be like.. Until there is a persistent exploit anyway.

 

[Vorde]

I don't own a PS4 yet but this is interesting. I think I will wait to see the scene release a full exploit that's persistent before I go out and buy one. Might have to find one on eBay that has the lower firmware, but I'm hoping I can get my hands on one in this city

No, I don't think so or developer will mention that somewhere. They didnt say anything about it thought.

 

[kublai]

I'm hoping it's a perm hack like the PS3.

 

[spotanjo3]

I'm hoping it's a perm hack like the PS3.

Yeah.

PS4 emulator when?

 

[Devin]

Got it all set up on my PS4 after updating from 3.51 -> 4.05. A user by the name of AlAzif created a really painless way to host the exploit locally as well as automatically send the payload over to the PS4 without messing with Netcat.

https://github.com/Al-Azif/ps4-exploit-host

(EDIT: The exploit is lost when the system completely loses power. The exploit's retained if you put your PS4 into sleep mode however.)

thanks this might be helpful for me as i'm stuck in idu loop now.

DONT BE STUPID LIKE ME AND TURN ON IDU if so you will have to use staff mode code and it's very dodgy running exploit so far I can't get debug to open but I think it's payload or memory issue
