The Bat! got keygened

nanobit · #1 08-22-2009, 23:44

After keygening WinRAR, now SeVeN has keygened The Bat!. I think it is using ECDSA-800. It seems he has found a new way to factor the numbers or bought a super-computer

P.S: I don't know much about grid computing

Is it really significant how it was made? You can see this nice release, anything else is a mystery.

Well anytime a program has gone without a major break in their registration security, (Total Commander, Winrar, etc...) everyone is naturally curious in general, especially if SeVeN found a new attack style on ECDSA or just how in general he did it. Such a tutorial would be an amazing read, but will probably never happen.

Yes, it is very interesting how it was made. It seems the hole exists in the key generation scheme. Anyway, it is great results.

I think SeVeN will not give this information. This topic will be a second flood-topic like WinRar with stupid thanx. My post means only that.

Even if exist new style attack on ECDSA, you can not use this technology as your own. So, right way try to find and work hard on another attack. There many examples (ASProtect keygens by TMG & ECLiPSE, RSA protected apps breaked with grids, etc.)

I agree my friend. I was only attempting to explain nanobit's curiosity.

SeVeN is great keygenner

nanobit · #8 08-24-2009, 15:27

I didn't start this thread as a "thanx" one for the keygen. I just wanted everybody to know that ECDSA is defeated AGAIN, and that's not something unnoticeable.

I wish 1536-bit RSA to be vulnerable also, but

...

Syoma · #10 08-24-2009, 21:07

I don't think that ECDSA is vulnerable. IMHO, it was attack on implementation.
p.s. Forget about hasp, man

That is true, so we still can do something to find the right way.

OHPen · #12 11-10-2009, 06:35

I also agree with the a few other guys that the attack was started over a vulnerable implementation of the algorithm.
propably somebody who found a weakness in the algorithm would rather say nothing at all or he/she would wrote a very detailed document on it, because of the importance of that fact.

just my 2 cents.

I'm thinking ... SeVen will be able to keygen CRO 239 bits (120 chars ECC) Flexlm target licenses??? Atm LND and ZWT cant do that, or not?

see more here

Thank you for your observations, what do you mean by ECDSA-800? Could you please explain in detail what ECDSA-800 is?

And its key has a length of 800 bits.
