XorHack: The PS3 Exploit Toolkit is Now Available!

800°
251w ago - Today xorloser has shared his XorHack: The PS3 Exploit Toolkit which allows you to call lv1 syscalls (level 1 system calls) from a normal (userspace) program and run the software required when triggering the PS3 exploit from a normal userspace program.

To quote: I finally found the time to complete the PS3 exploit toolkit software I mentioned to in my previous posts. I call it [Register or Login to view links].

It allows you to call lv1 syscalls (level 1 system calls) from a normal (userspace) program. It also lets you run the software required when triggering the PS3 exploit from a normal userspace program. To give an example of how it can be used I have included the following example programs:

ps3exploit - Runs the software required to exploit the ps3, it loops a number of times which can be specified as a parameter. (This still must be used along with the "button pressing", it will not exploit the PS3 via software alone).
dumphv - Dumps the hypervisor to a file in the current directory.
dumpbl - Dumps the bootloader to a file in the current directory.
dumprom - Dumps the system rom to a file in the current directory.

The XorHack package contains full sourcecode...
 

Rumor: Sony to Remove OtherOS in Next PS3 Firmware Update

1200°
253w ago - Update: Sony's Geoff Levand has now [Register or Login to view links], to quote: "SCE is committed to continue the support for previously sold models that have the 'Install Other OS' feature and that this feature will not be disabled in future firmware releases."

According to Owen Stampflee, a Linux Product Manager at Fixstars Corporation, Sony will remove OtherOS in the next PS3 Firmware update due to the recent GeoHot PS3 Hack.

Although this comes as no surprise to PlayStation 3 Slim owners, where OtherOS is already removed, it would contradict Sony's previous statement to standard PS3 owners.

To quote: "Everyone,

I've caught a rumor from a reputable source that the next firmware update for old PS3s will remove the OtherOS feature...

I'm not sure if it's true or not but it's in the best interest of the YDL community to spread the word.

Cheers,
Owen"
 

GeoHot PS3 Hack Exploit SX28 Hardware Tutorial By Xorloser

1000°
254w ago - A few days ago xorloser propered the GeoHot PS3 Hack Exploit for all PlayStation 3 Firmware versions, and today he has detailed the required SX28 microcontroller hardware and shared the source code.

To quote: This post will deal with the hardware required to trigger the PS3 hypervisor memory access exploit. The purpose of the hardware is to stop the PS3 from saving a change to a value that we don't want changed. The PS3 saves this changed value by writing the value to RAM. Therefore in order to stop it from saving the changed value we need to stop this write from occurring.

The PS3 sends the write command to the RAM over some control lines, so we interfere with these control lines when the write command is sent. The result we want is having the PS3 think it has successfully written the value to RAM, but the RAM didn't receive the write command due to our interference and so it did not perform the write operation.

The easiest (and moderately safe) way to interfere with these control lines is to ground them. This is done easily enough by connecting a wire between one of the control lines and ground. The tricky part is timing it just right so that it only interferes with the write...

255w ago - Today xorloser has 'propered' the recently released GeoHot PS3 Hack in attempt to accomodate all PlayStation 3 Firmware versions with the exploit.

To quote: As I'm sure everybody heard, the memory access exploit for the PS3 hypervisor was released recently by geohotz. I was finally able to replicate his hack so I thought I'd take the time to help out others who may also have trouble due to being linux n00bs like me.

If I were to post everything at once it would be too much work and I'd never get around to it, so I'll post bits at a time to ensure I actually do post it heh. Today's post will talk about the software side of the exploit.

Please note that the geohotz exploit software was hardcoded for the v2.42 firmware, I have made a small fix that attempts to dynamically support all firmware versions. I have only tested and used it on v3.15 however.

The first step is to install Linux on your PS3 which means of course that this will not work on a slim PS3. I tried a few different Linux distros and after various different issues I settled on using...
 

How the PS3 Hypervisor was Hacked and Dumped by GeoHot

750°
256w ago - A few days ago GeoHot Hacked the PS3 and dumped the PlayStation 3 hypervisor lv0 and lv1, and has now updated his blog with a technical writeup [Register or Login to view links] on how it was done written by Nate Lawson at rdist.root.org.

To quote from the article: "The PS3, like the Xbox360, depends on a hypervisor for security enforcement. Unlike the 360, the PS3 allows users to run ordinary Linux if they wish, but it still runs under management by the hypervisor. The hypervisor does not allow the Linux kernel to access various devices, such as the GPU. If a way was found to compromise the hypervisor, direct access to the hardware is possible, and other less privileged code could be monitored and controlled by the attacker.

Hacking the hypervisor is [Register or Login to view links] required to run pirated games. Each game has an encryption key stored in an area of the disc called [Register or Login to view links]. The drive firmware reads this key and supplies it to the hypervisor to use to decrypt the game during loading. The hypervisor would need to be subverted to reveal this...
