New raw idea for a possible exploit. (and its not HTML this time :P)

[Buddy4point0]

well than where the hell is this plugin located!!

oh and thanks Fanjita for pointing out the server app thing to me i was thinking of it more as a direct transfer of data between the flash and the usb device. :P

the plugin (prx) is in the flash but that doesnt mean it has writeable acsess to the flash. but still it could be hackable

[Triv1um]

yeah but surely something as stupid as the memory stick reader has a prx, that doesn't mean its hackable.

still its a idea, I wouldn't have a clue were to start =p

[Cloudhunter]

Fanjita severely debunked this. Probably not gonna happen

A few things you must know first...

The camera only sends a video feed to the PSP and never actually writes files to it. The system software basically takes screenshots of the video feed and writes those files to it itself.

You see the top of your PSP? I am going to guess that the top of it has (from left to right, with screen towards you) an IR port, a circular docking hole, a USB logo, a tiny rectangular hole, the USB port, another tiny rectangular hole, another circular docking hole, and a UMD open switch. Believe it or not, the camera connects to the PSP via the USB port AND the two tiny rectangular holes. (Proof: use two tiny pieces of paper or something to block the connection between your camera and your PSP. It will not work. I found this out cause there used to be some crud in there that kept it from working and it wouldn't work until I used a toothpick to sc$#@! it out.) I don't know if any USB devices can connect to the PSP like the official camera because of that.

The "install new software" PC glitch won't work. Why? Sony isn't gonna release PSP camera drivers to your computer. I believe that the drivers are actually stored on a tiny flash chip inside the camera itself, and I would think it to be near impossible to grab them off of there. Even if you did, they probably would be incompatible with the PC.

But don't let all your hopes down. This is coming from the person who didn't know Russia was involved in WWII until 15 minutes before my test on WWII.

when you connect your psp to a pc via usb and you press the camara icon in the xmb, windows will say "new hardware found"

So I think its possible...

I'VE GOT IT!

I just downgraded my sisters!

Here's the fil---

Dammit I deleted it! oh well!

Thank you for the information IndianCheese very useful!! but the weird thing about this mode is how it actually continually sends out a signal through the usb port even when the official camera isn't present because until you hit back on it windows will still recognize it. and during this time when it is continually searching for it seems the best because the first file that it would receive would be a confirmation/identification file from the camera. so counld't you if you were able to encrypt a file that sony might recognize on the psp (preferably the dumped camera data :P(if its possible)) and send that over the usb connection and..... this is gonna be harder than i originally planned. (it always ends up that way ;( ) and then just like soder a wire to the cameras metal peices and... yeah.... hm.... well i still think it is one of the best shots we have

(second option would be some sort of buffer overflow attack as fanjita metioned)

EDIT: very funny parkermauney

Has anyone given a look at using PSX homebrew converted to an EBOOT as a vehicle to 'break into' a non-modded/downgraded PSP?

[pt9087]

pt9087 - sorry fella', but I believe that hack went out of the window with FW3.10 - the code that deals with save-game loading has been properly patched now, as it was a flaw in the previous attempt to patch it that allowed the latest (3.03) downgrader to work with older (equally flawed) versions of GTA. Essentially, even if a great, glaring hole is found in another release, the firmware has compensated for the possibility. Result; no GTA downgraders for 3.1+ owners.

Noobz.eu covers the subject pretty well on that score.

I'm waiting for someone with a bit of savvy to completely debunk the USB suggestion. While I think it's similar to attempting to hack into a home alarm system via the water pipes, I can't claim to know enough about it to say anything definitive. For all I know, the PSP camera-handling code could be susceptible to the same sort of buffer overflow attack that allowed the TIFF exploit to work initially.

It's certainly not as bizarre as suggesting kernel-mode access via HTML!

That was also said by many people after the 2.60 downgrader, do you know that for a fact???... NO! people also say that about Tiff! but nearly anything can happen if you look at the history of downgraders!

[White_Hawk_UK]

Tesseract - all homebrew is in eBoot form.

pt9087 - I'm not saying a downgrader isn't possible at all, just that I think the GTA exploit has seen its final version. Fanjita more-or-less makes this seem the case with his explanation re: GTA exploitation..
