It appears there is a new release but it can be considered as an "old release" coming to the PS4 Soon, UPDATE: the exploit has been released . A couple months ago we seen Team FailOverflow release the breadcrumbs to exploit v4.05 firmware with the details reveled on there blog ": The First PS4 Kernel Exploit: Adieu" Since that time developer SpecterDev has been on a mission to put the pieces together for a workable jailbreak (not an easy task by any means) on the PS4 (4.05 firmware)., Over the course of the past several months SpecterDev has spent many hours of work to get this exploit stable state usable state for anyone interested. He has done amazing work for the PS4 development community is a vital step forward for the PS4. Now 1.76 is not the only window for the PS4 but also 4.05 provides a new window that is now easier to obtain, but will this be enough to launch the PS4 Homebrew Scene to a new level?
In my personal opinion i think we have another step or two before the PS4 Scene breaksout Personally I am not as excited about this exploit as some are from an end-user perspective, i do not think this will be a "golden firmware" just as i did not believe 1.76 ever was, both exploits have came to late in the PS3 life-cycle. Just as Team Fail0verflow themselves suggested in closing when they first detailed this 4.05 window and i quote "And so we say goodbye to a nice exploit." . As we can be extremely thankful for the contributions from Team fail0verflow we can also gather through comments and actions that they will not be the ones to release an exploit themselves or be the ones to give the fuel to something current, i could be wrong here but this is what I have gathered. So this exploit originating from them i would say does show there is a bit of steam knock off the exploit potential impact for launching a community, I think this is a great step forward but i do not think a 2nd PS4 is needed quite yet, i think there will be more to come as times passes, but that is your choice and i can only offer a different perspective then what others have been given, i would just point to my track record on being correct in many of these situation ;p . This is exciting on many levels but not sure its worth buying a 2nd PS4..?..?..
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 exploit does include a loader that listens for payloads on port 9020 and will execute them upon receival.
You can find fail0verflow's original write-up on the bug here, you can find my technical write-up which dives more into implementation specifics here (this is still in progress and will be published within the next few days).
The following patches are made by default in the kernel ROP chain:
- Disable kernel write protection
- Allow RWX (read-write-execute) memory mapping
- Dynamic Resolving (sys_dynlib_dlsym) allowed from any process
- Custom system call #11 (kexec()) to execute arbitrary code in kernel mode
- Allow unprivileged users to call setuid(0) successfully. Works as a status check, doubles as a privilege escalation.
- This exploit is actually incredibly stable at around 95% in my tests. WebKit very rarely crashes and the same is true with kernel.
- I've built in a patch so the kernel exploit will only run once on the system. You can still make additional patches via payloads.
- A custom syscall is added (#11) to execute any RWX memory in kernel mode, this can be used to execute payloads that want to do fun things like jailbreaking and patching the kernel.
- An SDK is not provided in this release, however a barebones one to get started with may be released at a later date.
- I've released a sample payload here that will make the necessary patches to access the debug menu of the system via settings, jailbreaks, and escapes the sandbox.
I was not alone in this exploit's development, and would like to thank those who helped me along the way below.
Great news for the PS4,this is a great step forward for development but i caution people getting too excited about this and running out to buy a new PS4.
Personally I will get excited when we see a CURRENT FIRMWARE exploited, That will be the start to the Explosion of PS4 Homebrew IMO.
Update: via @Red: Much like ps3xploit I have hosted this files for others to use, in case anyone would like to mess around with this but doesnt feel like hosting the files themselves. http://redthetrainer.com/ps4/

PS4 4.05 Exploit for PS4, Released by SpecterDev..

Milestone Update for Orbital - An PS4 Emulator by @AlexAltea - now with (very first) Video Output!Nearly a year ago, Developer @AlexAltea showcased us an early-stage Version from his own PS4 Emulator called Orbital. The very first Version was on a minimal stage by running several code examples on a Terminal within Linux only but this was already impressive since as you probably know, both the PS4 and standard Computers shares the same x86 CPU Architecture. But the CPU isn't the only thing the PS4 shares with a standard PC. Since you need also a lot of GPU Power to run your Games on a Console for General, it is getting quite usual that those big players like NVIDIA or AMD are collaborating with the Console Manufacturers to deliver them with special-designed Graphics Processing Units for the Consoles you own. Even when we talk about "Special" GPU's, you already recognized by yourself that if you go further in newer Console Generations, you realized that the internal GPU used inside each Console is having more and more similarities compared to a standard GPU. With that result in mind, Developer @AlexAltea showcased yesterday that his Emulator Orbital is capable of running the Safe Mode of the PS4 together with getting a Video Output from that mentioned Safe Mode as well, which leads to the point that his Emulator showcased the very first Video Output from a PS4 emulated by a PC! Do I have to say more? Continue reading
4.84.3 STARBUGED (w/ COBRA 8.01) - New update in from Habib
Following the introduction of 4.84 STARBUGED CFW for the PS3, which also gave us the introduction of Cobra v8.0x from developer @habib, Has now followed up that cfw release with 4.84.3 STARBUGED (w/ Cobra 8.01) that contains some more candy for the scene. As the developer has provided new features once again with this update with the ability to Hardcode Kernel Plugins, which can be useful for things like MAMBA (a Cobra Alternative) as it can not be ran as a kernel plugin. Down below you will see the technical aspects of what this update has provided from Ps3 CFW Developer @habib.
RPCS3 (PS3 Emulator) - January 2019 Progress Report (+ useful Extras and Tools)A new Year, a new Progress Report begins. Kinda late for March, I know and yes it's not the first time I use this excuse for being such late. But the Team behind this wonderful PS3 Emulator RPCS3 thought about that instead of bringing you a monthly updated Progress Report only this time - which still shows some impressive Progress from each Month if you ask me - they decided that it would be a good start for the first Progress Report of 2019 to release some additional Tools together with the January 2019 Progress Report. So while you can enjoy their Progress for January both down below and on their Blog post (also linked down below), the Team behind RPCS3 teased several Tweets about their additional Achievements they did since the beginning of this year. You want an example? Well, maybe you didn't know about but since RPCS3 also supports a Basic Network Functionality, it will allow you not only to emulate some AAA Game Titles. It can be also useful to emulate other Non-Gaming Applications and various Media Applications as well. So there is no problem at all to watch some Videos using the official YouTube-Applications for PS3 via RPCS3, viewing the newest Episode from you favourite Anime Series on Crunchyroll or why not enjoying a full-length Hollywood Blockbuster on Netflix, for instance. How cool is that?Continue reading
