I never saw this day come when the PS3 would have been hacked. Just cant wait for the clever people to make some HomeBrew Applications for it. More power to the people. With its high specs, what endless capabilities are there.
As we have herd “geohot” has successfully hacked the PS3 to have full read and write access, bypassing the Hypervisor.
“Geohot” explains on his blog how he’s located a critical portion of the memory to attack. By allocating it, pointing a whole bunch of code at those addresses, then deallocating it he causes many calls to invalid addresses. At the same time as those invalid calls he “glitches” the memory bus using a button on his FPGA board to hold it low for 40ns. This trips up the hypervisor security and somehow allows read/write access to that section of memory.
A video showing all of this below. (more…)
