June 20, 2010 // 11:32 pm - Yesterday SKFU announced that his PS3 hacking team started a PS3 Blu-ray drive Project, and today he is back with a PS3 Exploit Loader and POC v0.1 release!

While many are still hoping for PS3 Custom Firmware, this proof-of-concept appears to mimick GeoHot's PS3 Custom Themes Hack Demonstration, however, instead of using PlayStation 3 .RCO File editing via RCOMage or similar, SKFU utilizes the Sony application p3tcompiler.exe from the official SDK.

To quote from SKFU: "So here is the result of the simple idea. The first code which is 100% PS3 only compatible. No flash, no bd-java or similar. The actual exploit is not finished. This is just the loader you will need and a proof of concept of the methode used to load it.

This is a beta version of the POC as I'm too tired to finish it now but I don't wanna' let you wait so long. Here you go:

How 2 Use:

1. Install loader.p3t like a common theme file.
2. Put loadme.fu on an USB stick's root dir.
3. Insert USB device into any PS3 USB port.
4. Enable the theme you just installed before.
5. Hello World.

How It Works:

The PS3 theme file is able to load the loadme.fu script from any USB port. The script is executed. The "loader" is for future-use aswell to load any .fu files which I'll release. Stay tuned for updates!"







Shortly following, SKFU elaborated on the PS3 Exploit Loader and POC v0.1, as follows:

"SKFU's Exploit Loader - What it is and what not
Some of you may expect a little bit too much out of this. The code used runs in a very restricted area. Currently we test how far we can go into direction "overflow" and system param's we can access.

So far it's possible to command the script a bit via system parameters like the clock. The clock can be used as provider of input, for example to command simple textures in different directions or similar.

This is no exploit yet, if you may have missed that statement in the prior post. It's just a way to load scripts via USB now.

Further tests will show us what is possible at all. The information needed was given to several more devs so they can take part in the action.

- SKFU"

Yes, it's been confirmed several times in the last 8 pages including HERE to work with 3.30 FW. Basically it works with any PS3 Firmware version that supports Dynamic PS3 Themes.

Correct, and yep... I believe this is just a side project they stumbled across during the ongoing PS3 Blu-ray Drive Project.

so let me get this right this exploit loader will be like where you install the theme and when we have the exploit which is not yet released by skfu. it will load it so basicly this theme does nothing yet, but it will do when he releases the exploit or am i getting something wrong?

oh and also is this exploit the one which he did the backups or is this another project he has cause i read that he had succeeded on running backups from hardrive which is really big news.

well guess only time will tell... just hope he doesn't become like geohot and doesn't share.

This also works with SD Cards if you change Dev_usb to Dev_sd.

From what I see they are using some XML property to load resources from USB. It's not really an exploit yet unless you consider something the vendor left in as such. If you could script it you could fuzz it, question is what LPAR is that.

With this exploit, although its run in a "sandbox", can it access files? If so, can it write to files? If it could, it would make getting into areas previously only accessable with the geohot exploit possible to the average end user.

If the images it needs can only reside in the "loadme.fu" file itself, would it be possible to domehow corrupt the USB to make it read further than whats actually there, say getting a 512mb USB, and putting a "loadme.fu" file that is supposedly 4GB on it (mess with the partition file headers, it's definitly possible, my USB has become corrupted before and had massive files appear that cant be deleted)?

From there, if the PS3 loaded something dodgy, like RAM or part fo the harddrive when it exceeded the size of the USB, you could get the loadme.fu file to read from that area, and show it on the screen, maybe even write to it. It's all hypothetical, and I don't really know the PS3's security, but it may be worth a try. Just my noob thoughts on the matter.

people need to more optimistic, this gives confidence/self esteem to the devs which ultimately equals = win.

This is just a Proof of concept. Can't wait to see what comes next. More useful codes run maybe..
