Vita hack: the webkit exploit fully explained (+ more code for you to look at!)
This was kind of out of the blue: Developer acez just posted an article on his blog explaining all the details of the Webkit exploit that was recently revealed for the Vita, describing how he and a group of friends worked on a Webkit vulnerability on the Vita, and leveraged it to run native code. It has been explained to me that although this is the same vulnerability that Davee used for his work, the two groups worked completely separately on their exploits.
The read is extremely interesting, and I won’t pretend I’m able to summarize it in a way that would do it any justice, so I suggest you just read it.
A cynical summary for people like me who have been in the PSP hacking scene previously would be: “ha, the security on the PSP was a joke, now we’re talking”. The article truly shows that the exploit was not only about digging for CVEs and quickly and dirtily implement them on the Vita. Between the absence of a debugger, ASLR, sandboxing, no JIT, and other bumps in the road, acez’s post clearly explains this was not easy. At all.
From the scene’s perspective, it’s interesting to see that the main people behind this work (freebot, acez, and John The Ropper) are – as far as I know – not people from the PSP or PS3 scene. They seem to be, however, very, very well seasoned hackers (at least acez seems to be a regular CTF – The hacking ones, not the Quake ones – contestant). The things they pulled off, which I understand where very helpful, behind the scene, to some of the releases we’ve seen over the past few days, were not an easy thing.
Credits
Johntheropper and freebot worked with acez directly on the exploit. In addition, he credits Yifanlu and Josh_Axey for their help on the Vita, as well as Acid_Snake and Codelion, and everyone else who “made this possible”.
Downloads
The exploit and all related work can be found on acez’s github. At this point I assume this is more or less the same work that has been released in CodeLion’s recent memtools_vita, but it is worth checking it.CodeLions memtool_vita is essentially based on some of acez’s early work. the repository contains webkooz (a basic memory tool on which CodeLion’s code is based), and an SDK named akai, which will help people write basic homebrews.
What’s next?
Let’s hope that the interest of acez, JhonTheRopper, and freebot for the Vita will stay for a while. As mentioned in the blog article, there’s still a lot to do: Webkit is sandboxed, and without additional exploits, the scene will not be able to gain “full” native access to the Vita. From a personal point of view though, I would surely be happy to start seeing a simple SDK, and some simple homebrew, in the sandboxed Webkit exploit. Just for the sake of it.

I would like to see a simple homebrew run too, thx for the news =)
سلام.شرایط خاصی نداره. مال بنده هم نیست. سایت chiilick.com رو باز کنید و عضو بشید.برای عکاس شدن جای خیلی خوبیه.
Krydser fingre for dig Emma! Det er vigtigt at have den rigtige mavefornemmelse, nÃ¥r det kommer til noget, man skal bruge sÃ¥ mange timer pÃ¥.Hvor arbejdede du henne, hvis jeg mÃ¥ høre? 🙂
Asali, I'm not saving the best for last. I don't have a clear favorite I'm afraid, Trayee and Bombay Bling are both great with Mohur coming close second only because it's not the type of perfume I wear (it's too nice and proper for me). Review coming soon.And I don't think you should worry about cedar here, it's not even remotely strong, others are strong enough to keep it checked.
nice. we need loader and sdk
I think the first thing to do, as impossible it sound, is check if with this exploit we can get RW privileges on the memory card and/or the internal memory, with that we can start developing tools using reverse engineering of the current files on the vita, I know it sound easy, but getting RW privileges on an encrypted memory (and getting the encryption key) using a webkit exploit is really, really hard, maybe yifan can achieve it, or maybe no one, hoping someone reverse engineer the vita memory card, that would be the entry point for Homebrew.
Reverse eng the files on the internal memory is pointless.
Plus we have something so much better to reverse eng – the actual memory of a working vita (uncrypted)
depends, if eboot.bin is plain file then it’s doable.
I have no spare vita to test these but i’m sure app0 is a jail and read-only
enough steps, a lot of tools, complex.
Please let one of the first Homebrews be a Doom Port 😀
First homebrew will be “Hello World”.
Second homebrew will be “Pong”.
Third homebrew will be “DOOM”.
It’s always that way. 🙂
They lost me at the first “ROP Chain”. I’m a RealBasic guy, not a C++ or JavaScript guy. The first page of just about every C++ book gave me a headache so I have real respect for what these people do since it’s all Japanese to me. I would’ve said Greek but I think Greek would be easier to learn than C++.
I guess I will eventually upgrade my one Vita to 3.18 when the time comes. For now it will stay on 2.10.
fortunately i can read both Japanese and C++ :p
Put a bounty in vita hack, what do you think?
Well that’s how they do when they gonna hack new android
But i don’t think there’s that big vita community and money isn’t everything
I know! Call geohot – he will hack vita for less then week I think
Geohot isn’t some god you know? Besides, didn’t the agreement sony and him settled on include him staying away from Sony Consoles in the future?
Yes, but he could still do out of the spotlight + he hinted at hacking a new Sony phone at the time of court just to be cocky. The Vita doesn’t seem so popular as first PSP but more of a reason to exploit for custom advantages.
Lol
That’s like asking an inmate to kill someone on the streets.
Geohot is way overrated, I remember him as the guy who was hated in the whole iOS scene because he released his exploit to early. Rookie mistake if you ask me.
Didnt the Ruling in the whole Apple thing say it is perfectly Legal to Jailbreak a Portable Device as long as it does not involve Piracy?
This is so great news when we can finally download and steal vita isos. This will be great for the vita look what happened with the psp we could steal and download like crazy. Keep up the great work.
Wololo’s site is not supporting piracy and this sort of posts should not be posted or removed.
please. Piracy isnt that evil. If you use a emulator, than your pirating. Also piracy doesnt equal stealing!
It does. Unless you buy the licence after or before of doing it.
Also, If you use an emulator and you’re emulating a game you already paid the licence for It’s not piracy, or at least, not stealing as the usual pirate does.
Just to clarify: Emulators are legal but the ROM has to be ripped from your own, legal copy of the game you want to emulate. Downloading ROMs is a no go.
Do you mind if I quote a few of your articles as long as I provide credit and sources back to your blog? My blog is in the exact same area of interest as yours and my users would truly benefit from some of the information you provide here. Please let me know if this alright with you. Thanks a lot!
I consider this is among the so very much significant info personally. And now i’m glad studying your article. However want to observation upon some common issues, The site taste is excellent, the articles is actually nice: D. Good job, cheers
Nice bait mate.
You mean “gr8 b8 m8” now “w8 for the h8 and r8”
I love all the new attention that this exploit is getting, because a month ago I was unsure if anybody was going to try anything to get a native exploit. This is also a great so article which will encourage programmers to get their hands dirty. Ofcource a small homebrew or a native hello world with touchscreen interaction would be great, but searching for a real exploid is way more intresting if you ask me.
Will this come out soon does that mean we can download games for free? That’s the reason to hack for everyone.
Engtihienlng the world, one helpful article at a time.
Köszönöm hozzászólásait. ahány ház, annyi szokás, ahány séf annyi recept. az én hunkar begendim ilyen. A legtöbb receptet egyébként egy isztambuli török szakácsnőtől tanultam, lehet vele vitatkozni:)
Possuo uma Santa Fé 2008 e preteendo trocar pela 2011 ,pois gostei da mudança do motor p 276v.Se possÃvel gostaria de saber quando chegará ao Brasil e estimativa de preço . Obrigado
Until I found this I thought I’d have to spend the day inside.
Superb, brilliant weblog structure! I like your blog post 3CXPhone 5 adds video, BLF to free soft phone in Smartphone Look and method of writing,
It’s posts like this that make surfing so much pleasure
Well, I’ll definitely see Jenny! (exciting because we’re Walker sisters & have been friends online all year but never met in person!) and I’ll look for Shelley to say hello. Thanks, Sarah!
stop the ads. the whole point of you tube is to watch videos without having all the ***. do you have any idea what a scam all the internet advertising is anyway? how many people use ad-block for firefox? people use google to find what they want. marketing and advertising is about getting people to buy what they don't want or need. concentrate on getting people to what they want when they do a search. otherwise keep all the *** out it, and keep it the heck out of my face.
That’s the perfect insight in a thread like this.
wrong. the reason for hacking is for homebrew and to make a seemingly good software better. not everyone is a pirate
I dream of the day when a ps2 emulator released on vita <=-)-§-<
Although the vita GPU is stronger than ps2’s, its CPU isnt near strong enough when comparing to the ps2’s CPU.
Therefore..a ps2 emulator is most likely not possible, and even if it was, it will have to be made first by Sony itself, for us the community to copy.
I could read a book about this without finding such real-world aphecaoprs!
Great pics, definitely liking the last picture. Inspiring me to create a 3D room with interesting decal or wallpaper over the walls using mydeco.com 3D room planner. (Like the interesting light fixtures in the first picture too!)Thanks for sharing this!
As a native Texan, I so appreciated this post! I have had this "dip" many times, but I had no idea it had such an interesting origin. I can't wait to share this story with my grandparents next week!
Hot topic for me. Yesterday by the end of the day absolutely lost my temper and start shouting like never before in 2 years. The only one good thing is not on my colleagues creatives, but on “suit” MD:) Waiting for the call for the “Sorry man but we have to say good bye to you” meeting

so simply it is a dead end !
I dream about a Steam In-Home Stream homebrew.
like a geforce experiance’s mars and shield streaming server ?
why are those not compatible with psvita or ps3/ps4 !!!
Hey, that’s a clever way of thinking about it.
