At this week's Chaos Communication Conference, a group of hackers known as fail0verflow appeared to crack the PS3's randomized key cryptography and access the system's master code. The team demoed the alleged security flaw by creating a hack and installing Linux on the system.
It should be noted that Linux was originally advertised as a selling point for the PS3, until the option was unceremoniously removed via a firmware update. 



Unsurprisingly, when the newer PS3 Slim was introduced, Linux wasn't included because Sony claimed the OS made the system more "vulnerable" to key cryptography hacks.

Interestingly enough, what team fail0verflow presented on Tuesday illustrated the system's poor use of public key cryptography and how it was in fact easy to hack even if Linux wasn't present.

So, to hack the system and install Linux, the team first bypassed basic PS3 security measures like the chain of trust, a hypervisor, and signed executables.
