gaining cod4 keys

Hello
Is there any cod4 brutefotce cd key guesser? Just was curious if it would work. there are 20 chars and milions of cd keys available, so maybe it can guess some?
Cd key can be changed very simply, just write in console cdkey 1 - first 5chars , cdkey2 - secon 4chars etc. everything what is needed is checking if cd keys is valid and save in somewhere in txt.
Aluigi could you please anwwer what you think about it?

returning to the thread. If someone is going to make it -All numbers generated by the rcon guesser should be generated randomly.

woops - wrong section? sorry

as you have noticed it's pretty impossible to bruteforce a similar key, moreover without being "seen" by activision.

Yeah just tookmy calculator and counted that there is aobut 4.3 * 19^30 combinations. Just wondering how many cd keys would be valid? 10 milions or more? Anyway
probability of getting valid cd keys would be about 1 to 4.3 * 10^23 or more.
Hm i think that Activision wont detected it just turn your internet off theres no need to be connected with the activions server it would work without.

So maybe is there any way to check how the cd keys is coded or something. I mean if the game dont have to be connected with the activions server so there might be a way to recover how te cd key is checking in the game if its valid or not and then just generate your own cd keys according the recovered 'key valid system checking'

hope you get what i mean.

some games have system actually. for example they export some games into other countries and they have cd-keys starting with like 4023-.
ive seen similiar system on many games, that would make things bit easier, but probability to get a valid cd-key is extremely low. it might turn out that you leave it running for whole year and still find nothing.
however i think it would be worth trying, just to see what would happen.

also if im correct, there are tools that can do this. also you can generate your own using Luigi's tcpfp. i think it should work. you just use passwords pro to generate a wordlist of cd-keys (which is MASSIVE, like 1000tb or more) and let it guess. capture with commview and make it stop upon successful cd-key.

i think Luigi's right at end, you might end up with 1-2 cd-keys, but they would ban you for such an attack and patch it. make some filter that you cant change cd-key more than like once in 30 mins.

I will check if cod4 uses any system ithat is noticable.
If i use passwords pro to generate keys then how would i check if cd key is valid?

And about being caught by activision. Not sure if im right or you are but cod4 doesnt need to be connected with activision server to check if cd keys is valid or not.Cd key can be checked in offline mode so how would activision know that im brute force it?

uhm you making no sense. you do understand that there's lot of games where you can use a simple keygen to generate a valid cd-key, but it will not be valid online. why else you think that theres no online crack available for such games.
cd-key can be generated, but its only good for offline mode then, not online.
Luigi can you say this in better way ? i cant find correct words to say this.

I think i get you now.
Well there are a key gen generators that generate unvalid cd keys only for single glayer but its not what im going to get. I wanted to say that if there is something like a cd key generators that generate randomly. Not like another cd keygens that use a system for it (thats why all the keys are only for single player).

Let me explain it more:

1. Ineed a program that choose 5 symbol from { 0,1,2..,9,a,b,c,..,z}. All the symbols can be the same and after that send it to game using for example console which looks like cdkey1 ABCD.
After that in first field will appear 5 symbols of the cd keys. After that the program should repeat the proccess for another 4 fields cdkey2 ,cdkey3 , , cdkey5 and check if the key is valid. If key is valid game shows message " cdkey seems to be valid". If that message appears the program will have to save the key in txt and choose another symbols to bruteforve again.

i already said wht i would do. if Luigi is not interested in writing you a tool, then there's nothing else i can suggest.

as about random bruteforcer, you do realize that its more or less impossible right ? if its completely random, what stops the tool from repeating the old combination ? if it remembers every combination it tried, then its equal to a wordlist, which probably takes 1000tb or more.

probablity of repeating it is even less than generating valid cd key so that wont be a big problem

buck, please stop spreading your shit here. your calculation is even wrong because you don't understand the whole thing.

you will never get a free cdkey by guessing a valid from someone else.

theoretically if you generate a huge amount of cdkeys following a certain algorithm that is valid for offline play you will end up with a sequence of numbers (the cdkey) which corresponds to the one on the master server list. but chances are very very low or u'll need to be very lucky / use loads of resources.
