Today in this part of the course we will reverse a program to recover passwords in RAR files.
https://download.cnet.com/RecoverPassword-Rar-Password-Recover/3000-18501_4-78328724.html
The program is in .NET therefore we will not have to see assembly language, it will be much easier. When we open the program we see a tab that indicates if we want to register the program we click, and now we should be able to see a dialog box to introduce the license.
We introduce random characters and in the control structure it will be directed towards a false return value. Simply by modifying in memory false as true we would already have the program registered!.
And ready we would have the program registered for life.
