As a computer scientist, I am interested in how Sony PS3 protectionworks, how it was broken by Fail0verflow, the further contributions ofGeorge Hotz, and the steps needed to make the PS3 able to run Linuxonce again. Since I am actually a computer science professor, I amparticularly interested in how this information can best be taught toothers who desire to learn it. I do not believe there is anythingimproper, much less illegal, in teaching people computer science.

Request for materials: I would like to receive tutorialinformation on: Sony PS3 access protection mechanisms, the EllipticalCurve Digital Signature Algorithm (ECDSA), thestructure of the PS3 hypervisor, METLDR, signing tools, and any othertopics necessary for a person reasonably skilled in computer scienceto be able to gain full access to the PS3. It is my intention to makethis information publicly available on my web site here at CarnegieMellon.

What not to send: Please don't send me encryption keys (Ialready have them), cracking tool executables (my goal is to teachpeople, not provide convenient tools for piracy), or information thathas been obtained illegally through theft or fraud. Keep in mind thatreverse engineering is a legally protected activity under the DigitalMillennium Copyright Act (DMCA).

Why I am doing this: Sony is attempting to use the DMCA to denycomputer scientists the right to speak about technical details ofcertain Sony products. This assault on free speech is intolerable andmust not go unanswered.

2/9/2011 Update: Sony sinks its own battleship by retweeting the PS3 master key:

1/27/2011 Update: Judge Illston has granted the TRO againstGeorge Hotz despite the venue issue still being contested by Hotz'sattorney. And I'm out of town. Since CMU has a west coast campus inCalifornia and is therefore potentially subject to Judge Illston'sjurisdiction, I have disabled my mirror until I can get back toPittsburgh and look more closely at the current state of things.

1/19/2011 Update: We finally hear from EFF, which today blastedSony for 'sending a dangerous message' to computer researchers aswell as to Sony's own customers. And at, Dan Gilmor saysthat Sony has shown adeeper disrespect for its customers than other technology vendors.Gilmor vows to boycott Sony products until they stop treating people'like chattel instead of customers'.

1/16/2011 Update: Sony is facing a consolidated classaction lawsuit due to its disabling of the OtherOS feature. Thecase is Ventura v. Sony Computer Entertainment America Inc., in theUnited States District Court for the Northern District of California,case no. 3:10-CV-01811. There is a motion hearing on the calendar ofthe Hon. Richard Seeborg for February 9, 2011, so it appears Sony'searlier efforts to have the suit dismissed were unsuccessful. Hereare links to a casesummary and onlinedocket.

A reader points out that Sony was denied an injunction by a Spanishcourt in December 2010; Sony had sought to prevent distribution of thePS3-Jailbreak product. Details on that decision (in Spanish) areavailable here;Google translation here. Thecourt found that the PS3 is a general purpose computer whosefunctionality had been impaired by Sony's actions, and it refused toenjoin distribution of the jailbreak product even though prevention ofpiracy was a legitimate aim, because 'there must be limits to publicintervention in the protection of cultural works [Sony games]' (myparaphrase from Google translation).

Also in December 2010, Sony lost a criminal case initiated in 2007against a Spanish vendor of PS2 modchips. The court determined suchchips to be legal in Spain. The court's decision (in Spanish) is here; Googletranslation here.

1/14/2011 Update: This eurogamer.netarticle explains the crucial mistake Sony made that allowed therecovery of their encryption keys. And a quote from the fail0verflowTwitter page explains the relationship between what the fail0verflowteam did and what GeoHot did: 'We [fail0verflow] discoveredhow to get keys. We exploited lv2ldr, then got its keys. Geohotexploited metldr, then used our trick to get its keys.'

1/13/2011 Update: My light-hearted use of the editorial 'we' above shouldnot mislead anyone into thinking that I an speaking on behalf ofCarnegie Mellon. On all my personal web pages hosted by CMU,including this page, I speak only for myself, as does every otherfaculty member. We have a PR department whose job is to speak for theuniversity.

Two relevant quotes:

The purpose of the suit is to harass and discourage rather thanwin. The law can be used very easily to harass, and enough harassmenton somebody who is simply on the thin edge anyway, well knowing thathe is not authorized, will generally be sufficient to causeprofessional decease. If possible, of course, ruin him utterly.

Our friends at Sony are having another bad day: i.e., doing somethingbreathtakingly stupid, presumably because they don't know any better.This time they're suing George Hotz andfail0verflowforpublishing PS3 jailbreak information, as reported by EnGadget, Attackof the Fan Boy, and inevitably, Slashdot.The PS3 jailbreak allows PS3 owners to run the software of their choiceon a machine they have legally purchased. Hotz's site is

Free speech (and free computing) rights exist only for thosedetermined to exercise them. Trying to suppress those rights in theInternet age is like spitting in the wind.

Note to Sony lawyers: no doubt you're eager to rack up another billablehour by sending legal threats to me and my university. Before you godown that unhappy road, check out what happened the last time a largecorporation tried to stop the mirroring of technical information here:The Gallery of CSSDescramblers. Have you learned anything in ten years?

A reader points out that jailbreakingthe iPhone is legal in the US thanks to the efforts of theElectronic Frontier Foundation. What bearing this has on the PS3controversy remains to be seen.

Sony PS3 (PlayStation 3), one of the safest gaming platforms, has finally been cracked and enabling to run illegal pirated games and applications on the PS3 device platform. PS3 can only run those software or games which are digitally signed by Sony and controlled by DRM (Digital Rights Management) to prevent piracy.
But it was Sony Corp who made a big mistake by selling PS3 games on high rates making the crack for PS3 a highly demanded item.
George Hotz (or GeoHot), who first jailbroke and unlocked the original classic iPhone in 2007, has claimed been managed to find an exploit on the PS3 system for the machine to be hacked. The exploit, if further investigated and developed, may result in modchip or softmod that can be installed to PS3 to allow burned, backup or copied game DVD or CD to be played.

the Geohot exploit gives full memory access to PS3 and therefore ring 0 access from OtherOS. This exploit works on PS3 with firmware version 2.4.2, and most likely on most previous versions of firmware too. The exploit quickly allocates and deallocates memory in order to glitch the memory bus, so that the hypervisor thinks some repeatedly allocated memory is deallocated, allowing read-write access, and with some tricks read-write access to the main htab.

The exploit code has also been released by GeoHot to the hacking community, though it may not be useful for most end-users yet.

The ZIP package contains a shell script file (, a Makefile, an instruction, a C file (exploit.c) containing the hack program, and a screenshot (pokemehere).
Here’s brief explanation by GeoHat on the PS3 exploit:

geohot: well actually it’s pretty simple
geohot: i allocate a piece of memory
geohot: using map_htab and write_htab, you can figure out the real address of the memory
geohot: which is a big win, and something the hv shouldn’t allow
geohot: i fill the htab with tons of entries pointing to that piece of memory
geohot: and since i allocated it, i can map it read/write
geohot: then, i deallocate the memory
geohot: all those entries are set to invalid
geohot: well while it’s setting entries invalid, i glitch the memory control bus
geohot: the cache writeback misses the memory
geohot: and i have entries allowing r/w to a piece of memory the hypervisor thinks is deallocated
geohot: then i create a virtual segment with the htab overlapping that piece of memory i have
geohot: write an entry into the virtual segment htab allowing r/w to the main segment htab
geohot: switch to virtual segment
geohot: write to main segment htab a r/w mapping of itself
geohot: switch back
geohot: PWNED
geohot: and would work if memory were encrypted or had ECC
geohot: the way i actually glitch the memory bus is really funny
geohot: i have a button on my FPGA board
geohot: that pulses low for 40ns
geohot: i set up the htab with the tons of entries
geohot: and spam press the button
geohot: right after i send the deallocate call

And, the brief usage instructions:

Geohot Hack Ps3 Download Windows 10

Compile and run the kernel module.
When the “PRESS THE BUTTON IN THE MIDDLE OF THIS” comes on, pulse the line circled in the picture low for ~40ns.
Try this multiple times, I rigged an FPGA button to send the pulse.
Sometimes it kernel panics, sometimes it lv1 panics, but sometimes you get the exploit!!
If the module exits, you are now exploited.
This adds two new HV calls,
u64 lv1_peek(16)(u64 address)
void lv1_poke(20)(u64 address, u64 data)
which allow any access to real memory.
However, while the exploit may have been found, it can be quickly patched by Sony in new firmware update.
