Description: This video is simple demo of cracking a software. The tools used in demo are Hiew32 and W32DSM. In video a keylogger software bpk2009 is reverse engineered with Hiew32 and W32DSM. The objective is to reversed engineered the software and bypass the registration code. First bpk2009 is installed on the windows system. After that it is opened in W32DSM and by using text search option try to find out registration code. After getting it try to find the conditional jump address. In this case this is the address to which control will transfer if somebody enters wrong registration code. we note that address. Now just drag the executable on the Hiew32 to open it with it. Search for that conditional jump address previously noted and change as per as video.
