JaicraB has posted on his blog, releasing his OtherOS base exploit and source code.

To quote form his blog:
PD2:
Here you have a minimum base to build the otheros.bld. The functions are described.

Call table incorporates LV1 and ASM functions. This ready to assemble the mechanism of the exploit. I hope this helps those concerned who did not know where to start. It has been compiled with the toolchain pdaXrom.

Remember JaicraB, the guy who managed to dump the PS3 hypervisor and tell us how he did it? Well looks like he is back to work again and released his KeyFindPuP application and more information on his current progress.

To quote below (translated):

Good! For business reasons I have not had occasion to pursue my hobby. Although we have less time to devote some time still.

We stayed with the method of Dump LV2, but will not be entirely useful without appropriate software, which is why I open the door in case anyone wants to help do not hesitate.

Contact hadesteam@hotmail.com. HadesTeam? A small nonprofit group, we just like to learn. This group consists mainly of the following persons: JaicraB, DemonHades, Calimba, DanteHades and Druid. That said, do not hesitate to help.

Mainly we want to Lv2? As you know the PUP has a number of checks with Hmac_Sha1. If we make a clean dump of the process of installation of the Key PUP Hmac_sha1 achieve in this struggle to unpack a PUP to carry out changes and re-create the Hash.

How?

We need a otheros.bld as simple as cash. A BLD with built the exploit and a stand to dump the memory. If someone offers volunteer program, contact. Once we have the dump is necessary to search for the Key. I have designed a program which facilitates the task: jaic_Hmac_sha1_file.zip Provide us find the Key.

Extra Information

The installation of the PUP has three phases:
1. Checking the hash described in PUPHeader.bin
2. UPDATE to unpack the hard disk cache area Fat32.
3. Verification and update of hardware modules.

Process

Having a second hard drive formatted with the PS3 and have the BLD (see above). Enter the first drive and enter the recovery with the PUP in a USB.

The first process to run the PUP from the recovery checks described in the file hashes PUPHeader.bin. If everything is correct UPDATE unpacks the hard disk. At that time makes a reset and return to continue the installation.

At that time you restart and have lost the KEY, as it would be replaced by other data. Solution? Motherboard Keep constantly fed and cause instant shutdown.

“The next day the board will explain how to keep the system fed without being noticed. (Is curious to see the fan on the hard drive and other peripherals and the red light on.) Also explain how to cause instant off with a small bug on the BIOS controlled.”

With these two methods can turn off the PS3 at any time hold the RAM and make a Dump.

Objectives

Getting the key to restructuring a Hmac_Sha1 and PUP. The advantage of being able to change modules update. If you want to help hadesteam@hotmail.com.

Today, not having the special BLD we are investigating the BD player with good results. Greetings!
