January 21, 2012 // 10:18 pm - Since reporting on his last flaw uncovered, PlayStation Vita hacker SKFU has found a few new vulnerabilities in Sony's PS Vita handheld gaming system.

To quote via wololo: Few hours ago, developer SKFU (known for his work on the PS3, but also recently for some investigations on the Vita security) posted a screenshot of his Vita showing some HTML in what is supposed to usually show official messages from Sony’s updates or packages.

Knowing SKFU's passion for everything network-related, I'm assuming he's doing some tests using some local DNS changes... or maybe he managed to put some of his own files in an official package? That would be exciting.

In previous tweets this week, he mentioned he found 2 potentially usable vulnerabilities on the Vita

VITA is back to life, since last tweet found 2 new possibile vulnerabilities. If it runs good, news in blog this evening!

That was, however, 2 days ago, and his blog wasn’t updated since then, so I’m assuming he ran into a few issues. (the “back to life” comment refers to the official 1.52 firmware which bricked his Vita…or appeared to do so... which turned out to be that the battery had to charge for almost 24 hours before the Vita accepting to turn on, for some reason)

Obviously lots of this experimentation will probably not lead to anything, but for now, every bit on info on the internals of the Vita is interesting. Let’s keep digging

Also from SKFU (linked above) is an update on the recent PlayStation Vita 1.52 Firmware status below, as follows:

Ok guys we tested the possibilities on firmware 1.52 for a few days now. What I can confirm is the following:

  • Tech4's exploit still works
  • Wololo's HBL still works
  • Everything I research atm didn't change from 1.50 to 1.52

If that is fine for you, there's no reason not to update. Anyways, I have to mention that this can change without a firmware upgrade!

If you are online with your PS VITA, it can download and install silent updates for any application which runs in usermode and has nothing to do with system critical modules.

The good is, those updates are removed once the system is restored to the current firmware, so it would not be a major problem to remove a fix.

You don't need to do that cfwprophet but thanks anyway !

I was thinking to make a topic and put all what i did and what i'm doing on it but i think it's a little bit too late.

Some people probably don't understand why all that are on the firmware update/CMA topic.

It would be nice if we can create a topic for all the PS vita underground stuff (not only mine)

I think it is so only because PSVita isn't yet sold all over the world. Just it will be available for all contries more people will pay attention to the psvita underground scene.

However what you are doing is great, so thank you, man!

Ok it looks like nobody pays attention to my latest post it's ok and some people didn't understand what's going on that video.

Between 0 and 0.04 (picture shows the helloworld with my python/pyusb script available on PS3news) and about the video, i show that the PS Vita is really turned ON (and not off) and on debug USB mode.

This is just the beginning

After a test and some kernel playing.

Check the error of my PS Vita

Just to clarify that is not only a simple Hello world, it's also show you how to communicate with the PS Vita, in here we don't talk about the variant of the PS Vita but about the process of the PS Vita and as you can see i don't need to launch any program from the PS Vita to make a Hello World possible.

(simple example) -> The difference between the PS Vita and 3DS, it's that with the PS Vita you can communicate by USB Transmission, on the 3DS you can't.

BIG NEWS !!! I found the PS Vita USB Debug Mode ! finally ! i was working on it from the beginning with all my other stuff... finally it's here, i'm gonna make a video to show you. Get ready for it !
