Video: PS Vita Save Game Exploit Confirmed, HBL is Coming Soon


Sponsored Links
143w ago - Following up on the rumor from last week that a PlayStation Vita Hello World was achieved through a PSP Save Game exploit, today established PSP hacker wololo has confirmed it and stated that a Half-Byte Loader (HBL) is incoming!

To quote: Last week, an exploit on the PS Vita through the PSP emulator was announced by Mamosuke. The exploit was found by Teck4, and, we won't stress it enough, is a PSP exploit that gives us user mode access within the PSP emulator on the Vita. So this is not a Vita exploit per se, but it's still very cool.

Mamosuke confirmed this with a video a few days ago, and today I was able to confirm the exploit myself as shown in the video below (and I must admit that I spent way too much time working on that basic flame effect). The video below shows the exploit running on both a PSP 1000 and the PS Vita.





Here's also a screenshot since there is not autofocus on my stupid camera.

I spent a good amount of time today confirming some of my hopes that it will be possible to run HBL, at least to some extent, with that exploit. It doesn't mean I have ported HBL to the Vita yet, but I have strong hopes this will be possible. A handful of hackers are working on bringing HBL to the Vita (I won't mention their names here as I don't know if they want to be contacted on the subject), and it should be "relatively" easy to get something to work fairly soon.

(It should be noted though that the Vita is quite sensitive and crashed on me several times when it went into "sleep" mode from the exploit screen from there - am I just paranoid? - it seems it is impossible to reboot the machine for almost 10 minutes, which made me think I had bricked my vita could it be a anti-hacking security? If the console detects several crashes, it takes longer to boot, in order to prevent brusteforce types of attacks?)

I won't discuss any release yet, it doesn't depend on me only (this is, after all, Teck4′s exploit), but if I have my opinion to give on the subject, I would suggest to wait until the Vita is released in Europe and in the US. This gives us some time to polish HBL on this device, and hopefully the vulnerabilities we use to run HBL won't have been patched by then.

This is of course just a challenge with little to no practical interest once we publicly reveal the exploit (in particular, the game used in it), it will be extremely easy for Sony to patch it (or remove the game from the Playstation Store), so probably only a few people will be able to benefit from it but only time will tell, there is still hope, after all, that Sony doesn't care about a tool that allows us to run user mode psp homebrews in a sandboxed emulator.

I wouldn't be surprised if the US launch saw an even later firmware (1.6?). Hopefully the scene for Vita stays motivated and finds some reliable homebrew.

Indeed, at least he didn't reveal them specifically. I hope the launch firmware isn't very high for the US.

I hope a couple of exploits are kept secret until we actually can buy the damn thing.

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 [Register or Login to view links]: 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.

Wasn't it actually 1.51 as it was released around that time?
