174w ago - 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.

About the claim some user have read my news post on monkeydesk and posted it on gbatemp but i or you never sayed that you have HACKed the con. I named the news with "PS Vita Hot News" and translated some posts into german.

This guy then made the post with "PS Vita hacked?" or kinda like that and his first words written was like "nabnab claims to have the ps vita hacked" but some other guyes on gbatemp with a higher rep teached them they should learn to read

Now it seems they understand. But i haven't read anything about that to copy a savegame exploit to the vita we will need your work, the debug mode enabled to get full access to file sys and place the exploit where we need them. Also im sure we can get hands on on some nice importend files of the vitas fw. But anyway they will fully understand when it's time for it

USB Debug mode allow more than we expect but it's pretty unstable for now. Every person who have a PS Vita can do it and without anything else than a PS Vita and computer

Oh yes i saw that some people said that i claim i have hacked the PS Vita. I have never said i hacked the PS Vita, i explain what i have discovered and what my investigation/work is about.

Actually some executions on the PS Vita are pretty unstable and give me some errors (a security from the PS Vita that i need to fix) but i am working on it. I keep you informed for any updates of all my work and i will show you how to reproduce it when it's easy to do but need to keep it a bit as a secret before the EU/US release.

Nothing about my works but i really recommend to use the last version of openCMA http://code.google.com/p/procfw/downloads/detail?name=opencma_r3.7z on Windows -> thanks to Virtuous Flame

Ok let's back to work now

Nabnab: Does USB debug mode allow much/anything that couldn't be done before? Or is it still in the investigation stage? Also, is it hard to get into, or is it something anyone could do?

Yep, you can always start a new thread and we can merge or promote any posts made from it to the main page.. this was our ongoing thread for the Vita FW and Content Manager so people started posting here but if you wish to start your own I'm all for that too!

I'm gonna wait the BIG BOSS if he/she (she -> just kidding what ! you never know) want to make a new Thread and move all on this thread, it's gonna be more easy to follow and update the works.

You could do a new Thread named with "Universal Vita Dev Thread" or kinda like that. But best would be to ask the boss he also can move all the stuff from here which hase nothing to do with the OCM to this new thread then.

Great about the wiki and shows you that maybe more peoples recognize your work then yourself expect

I also was surprised as i have googled for my work and have seen where else it get spreaded.

I didn't know that have a PS Vita Dev Wiki until yesterday (somebody send me a private message on youtube, apparently my PS Vita stuff are available on it and i received some thanks) i didn't expect that much, it's really cool
