[PS3] GeoHot Opens All HV’s SPUs / XorLoser Preps Manual

1 Reply

Obviously notorious George Hotz has managed to get all 7 SPUs of the Playstation 3’s CPU under his control. This means although he cannot access the CPU’s root key, he now can decrypt everything that’s going thru these SPUs like datastreams of (encrypted) commercial games.

The PPU is higher on the control chain then the SPUs. Even if checks were to be added to, for example, verify the hypervisor before decrypting the kernel, with clever memory mappings you can hide your modified hypervisor.

In the meantime another hacker going under the nick XorLoser has released a more detailed manual of how to use GeoHot’s exploitation files and how to do the glitching.

Besides that XorLoser maintains a plugin for reverser’s beloved Interactive Disassembler (IDA) that contains special PPC instructions for Xbox360 and PS3.

Congratulations to GeoHot. Kudos fly out to XorLoser.

[iPhone] GeoHot Announces Latest Baseband Unlock

Leave a reply

George Hotz – by now almost any iPhone user should know that guy – hacked the latest baseband firmware 05.11.07. The unlock will be named BlackSn0w, well …

That means all carrier or SIM locked iPhones around the globe running this latest firmware can be used with different SIM cards from different carriers. Thus making holidays no roaming fee horror show.

Information about the unlock procedures will be released on BlackRa1n.com on Nov 04, 2009. Until then, enjoy GeoHot’s video proof:

Kudos fly out to GeoHot. Standing work, dude. But why the hell is there always Snow, Rain, Snow, Rain. Why no sunshine, guys?

[iPhone] GreenPois0n to Jailbreak all iPhones and iPod Touchs

2 Replies

What has happened so far

Some irritation is going on in the Apple hacking community. On the one hand GeoHot today announced that there will be a tool that will allow jailbreaking all iPhones and iPod Touchs, but as he wished to perform further tests he didn’t tell anything about the procedure.

The Chronic Dev Team on the other hand who seem to have been working together with GeoHot now released the technical details about this hack. Sadly as there is no GreenPois0n tool available as of now, the technical details are most likely useless for 99,9% of all iPhone and iPod users.

Reasons are unknown why the Chronic Dev Team released the information before a tool has been finished. But it seems GeoHot is not amused by taking these steps.

Update 2009, Oct 19th: GeoHot and the Chronic Dev Team tell they have independently found the bug that allows for jailbreaking the 3.1 firmware.

Enduser compatible information

According to mFX.ch (german only) the forthcoming GreenPois0n jailbreak tool will not require to bring the iPhone into DFU mode. The GreenPois0n will be released on the PirateBay*.

[iPhone] GeoHot releases iPhone 3Gs Jailbreak (Upd.)

Leave a reply

Update July 5th, 2009: GeoHot now also provides a Mac OS X version of the jailbreak tool. Windows and Mac versions ready for download at purplera1n.com…

That’s it with the 3.0 firmware and the iPhone jailbreaks. Apple has been beaten again. This time by GeoHot. Although the iPhone Dev Team seems to have their programs already prepared they preferred to wait with the release of an updated PwnageTool. GeoHot did not wanna wait and decided to release a Windows based jailbreak tool for the iPhone 3Gs called PurpleRa1n.

All three iPhone generations can now be activated, jailbroken and unlocked with the current firmware 3.0. Currently for the iPhone 3Gs there is only a Windows version available that is under strong beta testing. Anyway you can give it a try. The security whole that gets exploited in the iPhone 3Gs is well known as the 24k bug that has been found in january in the iPod Touch 2nd generations.

After jailbreaking, the iPhone Dev Team’s UltraSn0w should unlock your baseband.

Our recommendations

By now you know we are the conservative ones. We recommend: wait a couple of days. PurpleRa1n is still beta. But can hacks ever become stable? ;-)
