Question about ps3 jtag exploit?

[hunterrr]

Hi well as you see im new here i guess ill go ahead and say my names hunter and what not but i have a ? about 3 months ago i heard people found the jtag port on the ps3 and im wondering was there ever a real exploit about that or can someone inform me about this? isn't jtag the ability to run unsigned code and bypass RSA signed encryptions?

You are probably referring to this article: http://www.ps3news.com/ps3-hacks-jai...ed-and-mapped/

In short, the JTag port on the PS3 Blu-ray drive board was located and mapped out (the pin-outs were actually taken directly from a print screen of the $CE docs ) but these days they are almost always blown at production. There was no "exploit" ever mentioned.

To answer though, the resident Devs did test these exact points (and others) nearly a year ago and got nowhere as they were indeed blown.

hmm well thanks for clearing that up.

Well i don't know what the point would be since we can't rip/mod game iso's but i was just curious.

Yeah, the "general" benefit would be if the Jtag was open - in theory the memory could be dumped, ideally decrypted - then it could be RE'd , and an exploit found.

But, its much easier said than done, that kind of stuff takes time, and there are not too many skilled Reverse Engineers sadly!
