Video: GeoHot on PS3 Hacks at Nuit Du Hack Conference in Paris

850°
231w ago - Yesterday some videos were posted of GeoHot's iPad, iPhone, iPod coverage from Nuit Du Hack in Paris, and today we have some videos and a slideshow (PDF) of the PS3 hacks segment from the conference courtesy of malow82.

Forum user xrayglasses attended one of GeoHot's scheduled conferences, and stated the following to quote:

"He's booking for talks at 3 cons, I only got to see the one he just did in France. He's [Register or Login to view links] his talks around PlayStation 3 security, and when he comes on basically talks about i-products for two hours with a mention of PS3 in the last 10 minutes, literally in the same details as his blog.

In videos of it on youtube, you can hear people there laughing when he integrates his ego into his talk. I don't think he realizes what a small fish he is in the RE community.

He even said publicly that he was contracted to reverse the iphone which really...
 

GeoHot: Don't Update to 3.21, Promises PS3 Custom Firmware

1250°
243w ago - Today infamous PS3 hacker GeoHot has blogged that users should not update their PS3 entertainment systems to PS3 Firmware v3.21 when it is released this Thursday as it will disable the OtherOS functionality, and as incentive not to update he has promised the very community he isn't sharing details on how to dump lv2 with that he will work on a solution which could include PS3 Custom Firmware.

To quote: "A note to people interested in the exploit and retaining OtherOS support, DO NOT UPDATE. When 3.21 comes out, I will look into a safe way of updating to retain OtherOS support, perhaps something like Hellcat's Recovery Flasher. I never intended to touch CFW, but if that's how you want to play...

Two things, some people seem to think CFW will enable some sort of piracy. It won't. It'll just be a custom version of 3.21 that doesn't lose OtherOS support. Hacking isn't about getting what you didn't pay for, it's about making sure you do get what you did.

And this is about more than this feature right now. It's about whether these companies have the right to take away advertised features from a product you purchased. Imagine if an exploit were found in Safari on the iPhone, but instead...
 

GeoHot PS3 Custom Themes Hack Demonstration Arrives

1000°
245w ago - Today GeoHot has posted a few pictures (below) with the title "Custom Themes?" on the latest PlayStation 3 blog entry, however, no other useful details are available of the PS3 hack demonstration.

To speculate, it appears to illustrate modifying the PS3 GameOS XMB memory areas, but this was already known over a month ago when word first spread of the PS3 Hypervisor lv2 being dumped and reversed.

It's an RCO file edit, just like RCO edits on the PSP (almost same format too). RCO files are resource files for VSH plugins, live in the dev_flash, and aren't signed. To edit them on your system, patch your hypervisor to allow encrypted access to the partition (flash on old systems, hd on new), and mod ps3pf_storage. dev_flash is just a FAT partition, mount it in Linux and change what you'd like.

Nevertheless, it looks like progress is indeed being made editing and replacing an RCO in /dev_flash/vsh/resource/, although it would be nice if the information was made public so that other PS3 Devs in the scene could join in the fun.

From NDT: Le foto sono vere al 100% Ha modificato gli RCO dal dump della ram ma dato che non sono signed questo significa proprio poco. Si vede che stava cercando anche lui qualcosa da postare.

Rough translation: The photos are real 100% Changed...
 

XorHack: The PS3 Exploit Toolkit is Now Available!

800°
247w 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°
249w 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"
