97w ago - Following up on his status update for the PS3 4.0 Homebrew Enabler (HEN), today Sony PlayStation 3 hacker KaKaRoToKS has explained how the ECDSA algorithm works.
To quote: To popular demand, I have decided to try and explain how the ECDSA algorithm works. I've been struggling a bit to understand it properly and while I found a lot of documentation about it, I haven't really found any "ECDSA for newbies" anywhere.
So I thought it would be good to explain in simple terms how it works so others can learn from my research. I have found some websites that explain the basic principles but nowhere near enough to actually understand it, others that explains things without any basics, making it incomprehensible, and others that go way too deep into the the mathematics behind it.
ECDSA stands for "Elliptic Curve Digital Signature Algorithm", it's used to create a digital signature of data (a file for example) in order to allow you to verify its authenticity without compromising its security. Think of it like a real signature, you can recognize someone's signature, but you can't forge it without others knowing.
The ECDSA algorithm is basically all about mathematics.....
105w ago - Following up on the previous article and update for the 3.73 JailBreak, today Sony PlayStation 3 Hacker KaKaRoToKS has confirmed it is safe to update to PS3 Firmware 4.00 for those planning to use the exploit when it is released.
Below are some recent Tweets from him, as follows:
FYI, tested yesterday and the jailbreak still works on 4.0 so it's safe to upgrade (for those on 3.73)
Just got my progskeet today. Thanks uf6667 for sending it! It's so small!
Not much new to go on at the moment, but keep in mind the upcoming PlayStation 3 exploit will not enable PS3 backup managers such as multiMAN or Rogero as it does not include support for modifying Peek and Poke for lv1 and lv2 as outlined in the FAQ...
117w ago - Today Spanish PlayStation 3 developer S0uL of DemonHades has shared details on discovering the PS3 Firmware 3.6+ Keys, which comes a few days after Sony PS3 hacker Mathieulhleaked the 3.6 X-Platform-Passphrase stating that the PSN passphrase changed in version 3.70.
To quote, roughly translated: Hello demons,
Well, this is a tutorial for discovering the keys of 3.6 + made by S0uL and DemonHades (thanks for the info and review Demon) for all guys who think it is easy to discover the keys.
141w ago - Today PS3 hacker Mathieulh has tweeted some new details on dumping LV0 from PlayStation 3 3.60 Firmware and obtaining the new keys, followed by Ps3WeOwnYoU claiming he has already reproduced it to confirm it works.
Below are all the tweets, as follows:
xShadow125 You can update from your own pup only from 3.55 or lower, unless you have an exploit.
xShadow125 Of course that should be fixed in upcoming lv0 revisions anyway (By moving the ldrs to the top of lv0)
xShadow125 You run the 3.60 lv0, then you switch the nor, and pull the cell reset line, and you dump the extra KBs where the loaders are.
xShadow125 Basically you have a nor with 3.55 (or lower) lv0 and your own small lv1 code that does the dump, and 3.60 lv0 on the other.
xShadow125 You wont get all of lv0 but the part with the loaders shouldn’t be overwritten.
xShadow125 You can actually get all the 3.60 keys/loaders without knowing lv0 keys by dumping lv0 from ram with dual nor and signed lv1.
To those planning on building a 3.56+ pup for whatever reason, the files attributes changed, the group and user ids for the files as well.
141w ago - Today Myce.com (linked above) interviewed PS3 hacker KaKaRoToKS, who states that a PS3 Firmware 3.60 solution is indeed coming after reports and videos of a 3.60 JailBreak running code circulated last week.
Below is the the KaKaRoToKS interview in full, to quote:
What are your thoughts on the recent PS3 3.60 firmware cracking video that was uploaded and removed over the course of a day last week? Many dubbed it fake and said it was a debug PS3, but when we chatted with the guy who uploaded it he defended it as real and said it was a retail unit.
I’ve seen the videos, and I also talked to the people who did it. Whether it’s fake or not, I cannot tell as I have not been authorized by the authors to divulge what they did. All I can say is that they said they would never release it, so whether it’s fake or not has no importance, since in the end no one will have access to it.
However, as I’ve said to a few people on Twitter, the hack that was used on 3.55 and lower was unique and Sony fixed it. So, that’s...
