WinRAR 2.6
Type : Compression
Utility
Protection : Key file
Tech : Patching
Crack : WinRAR changed its registration method,now it is using
a key file protection.In which you have to send the programmer
your money and he will email you a key file "rarreg.key".
You have to put this file in the folder where you have installed
the program.Now if you run the program it will be registred.
So our attack point is where the program searches the key file and
try to open it.
So in SICE BPX CREATEFILEA
And now run the program.From this you can find the name of key file
something like "rarreg.*"
So create a fake file
Name : rarreg.key
-------------------------
xxxxxxxxxxxxx
DHEERAJ
-------------------------
And then run the program and trace...
