PlayStation 4 (PS4)

News Coverage of the PS4

Senaxx you may know from PlayStationSceneFiles has published a tutorial for user's interested in running Linux on PS4 with firmware v1.76. Now this will not show you to launch FailoverFl0w Ps4 Linux Port utilizing the recent exploits released but rather it will teach you how to run a basic linux rescue boot. Nonetheless its a very good tutorial for the PlayStation 4 Hacking Community as this is a very detailed tutorial from Senaxx
The PlayStation 4 Hacking Scene is evolving each and every day and the latest advancement will excite many as developer kR105 is filling in the missing pieces for everyoner to boot Linux on the PS4. As the developer unleashes a dlclose exploit that is fully functional, while we have seen in recent days news about a dlclose exploit it was not fully operational and was not complete, but now with this release the holes have been filled and the missing pieces provided along with a Linux Loader that comes compiled to make things much easier.
With all the positives coming from the PS4 hacking scene there is the unfortunate side of some negative stories or i should say what most likely appears to be a scam and i would personally proceed with alot of caution. There is a rumor that is circulating through various scene sites of a team that has a CFW for PS4 and also the same team is said to have a downgrade device in the works as well, this is highly unlikely and this team of unknowns does not give ANY information or any Proof of Concept to prove they have accomplished this.​
The PlayStation 4 Hacking community continues it progression. While we see countless fakes and websites promoting those fakes. We do however have some legit news from legitimate developer. bigboss (aka psxdev) who is a very talented developer who has created various PS4 Tools and published various finding on the console and accessiories such as the PS4 eye.The console hacker has a new Proof Of Concept (POC) that has been released on his personal github account as he announces via his Twitter account " Privilege scalation done " [break]ss[/break]w hich has gave the developer Root Privileges and the developer states "Next will be Jailbreak and sandbox". So what do you think about the progress on the PlayStation 4 (PS4) sound off below:

The PlayStation 4 news seems to be streaming in pretty well the last two days. Sony's beta firmware 3.50 is now available, then there was this leak. Now to top things off for the week we get a release from the fail0verflow team. Below you will find all that is needed to get your PS4 running Linux. However you will need your own exploit in order to utilise the kexec implementation released by the team.

    PS4 kexec implementation:


    This repo implements a kexec()-style system call for the PS4 Orbis kernel (FreeBSD derivative). This is designed to boot a Linux kernel directly from FreeBSD.

    This is not an exploit. It is useless without some mechanism of injecting code into the PS4 OS kernel.

    Building:

    To build a kexec.bin relocatable binary using the supplied Makefile, just type make. This will also build a kexec.a archive. You can either use the binary directly, or link the archive into your own project.

    If you link kexec.a with your own code, you need to supply the two symbols _start and _end in your linker script, as kernel_init() will try to remap all pages covered by that range as RWX (to make global variable accesses work). Alternatively, you can add -DDO_NOT_REMAP_RWX to CFLAGS to disable this feature, if you have already taken care of page permissions for the code. READ MORE.

In the PlayStation 4 Hacking Scene there has been some developments as it appears to be some leaked source code; "BadIRET kernel exploit" this exploit is based on some of the information that was provided by console hacker CTurt if you recall several months ago we reported here on information the hacker provided, since that time Cturt was working with someone in some capacity and the source code of that person was leaked along with some code of CTurt's (according to tweets from CTurt). Now there is conflicting reports as some are signaling this is a working exploit but Team REBUG developer @Abkarino has stated there is some missing parts to this leak and also provided some tips on compiling[break]ss[/break] of the source code also as seen in a tweet below. CTurt in what is now a deleted tweet has mentioned that Linux Port for the PS4 that has been released and maintained by team fail0verflow will not work in the current form with some assets missing.


For now this is not useful for the end-user, as more details are needed to truly figure out the significance of this leak, stay tuned as we will be keeping a watch as details arise.

John Koller, from the PlayStation US blog, has announced some info regarding the next beta release of the upcoming PlayStation 4 firmware update mentioned here. The update dubbed as "MUSASHI" brings a few social updates to the console. Those been 'friend notification', 'appear offline' and 'user scheduled event' to name a few. The firmware update, bringing it to version 3.50, also teases the remote play feature [break].[/break]for Windows & Mac users but do note that it will not be part of this beta so "you can look forward to it soon." The beta starts tomorrow.

Features released thus far:

John Koller posted on the US PlayStation blog the other day calling out for anyone interested in testing out Sony's next firmware update for the PlayStation 4. While been a beta tester for them you will get early access to the upcoming update and test out its new features before it reaches the masses. As mentioned in the post you will be able to roll back the update should you want to. You will need to have a master account for the console and need to sign up here for March's upcoming beta release.

PlayStation 4 hacker Cturt is back at it again along with qwertyoruiop as they deliver some new information for the PS4 Hacking Scene, as they publish "Analysis of sys_dynlib_prepare_dlclose PS4 kernel heap overflow" on Cturts github page. The exploit that is outlined in this writing was unfortunately patched "around firmware 2.00" so while its higher then some of the v1.76 exploits that have been talked about in the past by cturt, it still does help (at this time) user's who are on current firmware, but this research does give other hackers additional knowledge about the system and different ways it can be attacked. Cturt does not intend to release "any fully weaponised exploit source code" as he states, but the developer has shared lots of knowledge and is sharing hints and details about the path they have taken, to get [break]ss[/break] this working exploit..

More knowledge and details released can only help in the effort to get a working public exploit for the PS4, as thanks to fail0verflow PS4 Linux progress we should have something very nice awaiting when that time arrives. Among the details below you can view a few snippets of this article in the form of the Introduction and also the Conclusion, so be sure to read the complete article, link can be found at bottom of the page (Source).

That PlayStation 4 has had another firmware update released. There is not much to say about this one as it brings the console enhancements to system performance. Lets hope that these rather bland updates to the console are gearing up to something a little more special. Perhaps, as we watch the PlayStation 4 scene grow, we will see more interesting releases for the console as we have for the PlayStation 3.
