Re: Re: Brute force attack wHat is it? Monday, 15-Feb-99 13:48:23
Jeff, The nice thing about brute forcing is that it isn't just restricted to things like this. Imagine: you have a serial/name you want to reverse in some program only it is too difficult or time consuming to get to grips with. What do you do ? Here is one possibility: you have code typically like call pwdcheck or eax,eax jnz badguy or whatever. What you can do is make some program changes, depending on how the program works, to something like: call pwdcheck or eax,eax jz nowhere // make it loop to nowhere, or stop in some way inc pwd jmp tryagain // back to the call pwdcheck. Then let it run, until it starts to loop on the same place. The effect is that the program can be made to crack itself. Of course this can be set up in SoftIce when you get the idea, break in now and again to see how its going,etc... Cronos. Cronos |
