oct0xor Versus Cobra USB Dongle
Looks to me that developer oct0xor
has managed to reverse engineer the Cobra USB dongle.
In his blog he explains why the Cobra took some time to reverse engineer, why it was the last item on his hack list and the similarities between it and the True Blue dongle. He also makes a bold statement that Sony can learn something from the Cobra team regarding cryptography. He has created his own payload called OpenCobra
but also mentions that he is not sure of releasing his work. With that said here is a extract highlighting some of the more interesting bits of his blog. Should you wish to read the full story, follow the source linked below.

Finally I got my hands on cobra
it was quite a lot of time since I touched this last time. There was s good things happened since then eg. I reverse engineered usercheat and true blue, had done allot PS3 and not PS3 related hacking. There was a bad things eg. BlueDiskCFW, lv0 leak, allot of devs leave the scene...
Cobra was for me really "the last" thing I have to do.
3 days and now its all over.
Security is good enough, but not without big security risks. But it still the best crypto/obfuscation what I had seen on PS3. Sony have something to learn from this guys, especially now.
Cobra / True Blue almost identical, have the same source code, if you ever hacked 1 thing, 2nd wouldn't be a problem.
On the fourth day I took a decision to make my own "OpenCobra" payload. only clean code without DRM and garbage, to be able to port it to any new firmware, and change/add features. It took 2 days, 3000 lines of ASM, and you had seen the result.
ATM it based on 4.1 payload, plans for future is check/add new features from 4.4/5.0. Port to a new firmware (if cobra will not do this for me), and realize all nice innovations from new version of PSP emu, such as better emu accuracy, 3D and etc...
