Geohot Touts PS3 Hack

While the PS3’s defenses against unauthorized code have remained impenetrable up until now, hacker Geohot of iPhone fame claims he is the first to discover an exploit, a feat that will no doubt garner the attention of Sony. In a post on his personal blog, Geohot touts that he has managed to outsmart the PS3’s privileged-based hypervisor security system and gain “read/write access to the entire system memory” in addition to “HV level access to the processor.”

I have read/write access to the entire system memory, and HV level access to the processor. In other words, I have hacked the PS3. The rest is just software. And reversing. I have a lot of reversing ahead of me, as I now have dumps of LV0 and LV1.

3 years, 2 months, 11 days…that’s a pretty secure system

Took 5 weeks, 3 in Boston, 2 here, very simple hardware cleverly applied, and some not so simple software.

Coy on details, he further notes that idea behind this purported exploit is “not really patchable,” admitting that implementation of the logic behind it all may prove to be more challenging in future firmware releases if Sony decides to respond. And inevitably, they will. As of now Geohot has chosen to keep his findings under wraps but in all likelihood, it looks like we’ll be hearing more soon. Interesting times ahead, that’s for sure.
