    Hi,

    I noticed that the phone activation is done using a relatively short set of numbers,
    only 48 decimal digits, this is a bit under 160 bits.
    This is not short enough for a direct brute force attack, but isn't is short enough for an attack on the private key used by MS?

    I mean if the key would be recovered one could make a simple keygen to provide the unlock key instead of the phone service.

    Has this already been tried?

    There is no way since their method is something like RSA encrypted, spending months to generate a compatible confirmation number in ultra brute force machines.

    Well RSA with only 160 bits can be easily cracked, keep in mind that a signature is larger than the actual key, so they are using internally an even shorter key, so even it they are using EC Crypto its likely that the key is to short to be really secure.

    I don't see how this is different form a KMS activator? That can be found here in dozens.

    That is true but you will need to handle it for the most machines, not one.

    Every each try you will need to wait some seconds when using the DepositConfirmationID.

    Well, one would obviously not try to break it by supplying random numbers to windows and waiting for it to say OK.

    I think rather on the line of finding the public key in the windows binaries and than cracking it off site.
    Once one have the private Key every windows that internal validates against the previously extracted key could easily be activated.

    Actually one does not even have to recover the private key, if we know the public key and the algorithm used.
    One could replace the key in the binary that checks the activation with a own private key and than be able to activate the patched windows copy.

    Such a patch would be some what resistant to updates of the binary as it would not work by modification at offset but by search for a truly unique string (the public key) and replacing it with a own one. That is as long as MS does not update the binary such that the key will be stored in a obfuscated way. But at least for normal updates this shouldn't be a problem.

    permanent activation is overrated,re-activating every 6 months is not going to kill you

    Sure, but permanent activation using a small tool would be so elegant.

    Activation means independence, independence form MS,
    as it is now, you are delivered paying customer and pirate alike to the good will of MS.

    They can decide to for example to be strict with the non activated clients as to Windows XP times a.k.a. you can not even login.

    Independence form MS, To do what, use Linux/Mac.:confused:

    Isn't AutoKMS pretty much exactly that? It permanently activates daily. One little program :p

    MDL, the website where the same questions are asked daily by people who want to be spoonfed. I thought this was a website to share learning experiences, not help people who are too lazy to read stickies. I have no idea how some of you members with high post counts never have a fit and freak out on people.

    The sad thing is, some of the most rudimentary posts seem to be from sys admins.

    Hello Josh :) On my test configuration W8 Enterprise x64, successfully fake KMSed with MS Toolkit your Advanced Tokens Manager v3-5 RC4 displays "Error" This W copy isn't activated...
    ...any chance to fix this? Thanks

    You can still perm activate using the Media Centre keys
