PS Vita Hacker SKFU on Uncovering New Security Vulnerabilities

1300°
131w 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 [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...

135w ago - Following up on his previous update, today PlayStation Vita hacker SKFU reports that he may have uncovered a PS Vita encryption flaw.

To quote from his page: Since I finally have access to a retail PS VITA, today I started with some basic tests.

After a complete freeze of the system within the first 5 minutes after unboxing (*always happens to new consoles 4 me rofl*), I went on and noticed that there is a problem with the VITA's encryption functions and was able to decrypt some test files directly via the system.

I will post updates as soon as I have news

PS Vita Hacker SKFU Confirms PlayStation Vita PKG AES Key Changed

1300°
136w ago - Following up on the PS Vita 1.50 Firmware announcement comes news this weekend from PlayStation Vita hacker SKFU who has confirmed the PS Vita PKG AES Key has changed.

To quote from his blog: I just got my tried to unpack the [Register or Login to view links] for PS VITA and sadly I have to say that the AES key for PKG encryption and decryption changed.

The PKG's I used for my testings were pretty old and the key update was expected. Nevertheless it's a bit disappointing but a new nice challange

The PS3 can decrypt the new packages on firmware 4.00 which contains the new PS VITA PKG AES key for the PS3 <--> PS VITA content exchange feature. This means we can decrypt and get the content of the PS VITA PKG files via a 4.00 PS3. Sadly there's no solution to re-encrypt it again, yet.

Let the games begin! (again...)

To quote: This application is probably not of use for the community but some official PS VITA developers.

I required it just for some tests, but it would be a waste of codelines not to share it, so here it is:

PS VITA Live Area preViewer outputs various information about a game, including it's style it uses on the PS VITA.

To use it, simply choose the root folder of a PS VITA game. Then check the style in the upper right of the program which it is ment to be displayed with and choose the correct tab. All else is self-explaining.
