The only way it is going 2 get hacked, is by installing a modchip, or playing around with the hardware.
The reason why it is so hard because, the minute your PS3 boots up, it runs through 4 stages of security at all times. All 4 stages have secrets that will need to be decoded in order to reach the next stage, Sony has encrypted each hard drive to only work with a specific PS3, which eliminates the possibility of switching them out like memory sticks.
The hard drive is then read by the PS3 where it makes sure the drive is registered to the specific console. After verifying the hard drive, the PS3 continues to search for needed files to boot up the OS. This is merely the logo that appears or random files hidden in the system that will trigger the “OK” to boot up.
The hard drive is built in layers with the “bootflag.dat” being the first file read on each start up, which then leads into the DRM file and finally … the game files. Several files found in between each of these makes things even more complicated to bypass.
