    Resolved [RESOLVED] Vb6 - copy protection challenge

    Since I've been told several times that my copyprotection is a piece o cake
    I trust you but I'd love to see exactly step by step how you would hack my software.

    So I challenge you.
    Find attached my code, compile and run it. The mods won't allow me to attach EXEs so that's why give the source code.

    But do not cheat ! Do not "study" the code because you have to simulate you were only testing on an EXE which you don't have a clue on how it was made. ok ?

    The goal is to unlock the software for good, not for one single run of course.

    I'm not a hacker but read a bit a bout. Your protection is very easy for any beginner hacker because he will try the first lesson he learned
    1- Run the target application under debugger control.
    2- Show activation dialog and enter any invalid password.
    3- When wrong password message appear, back to the debugger and start analysis that code portion to find a way to bypass the wrong password message.

    How is the hacker going to DEBUG if he hasn't the source code ?
    I had to put the source code because the forum wont allow EXEs.

    You have to "pretend" you only have acces to a compiled executable.

    I'm talking about debugger (AKA disassembler) not vb6 IDE.

    YouTube full of videos learning how to hack a program, this one of them

    Debuggers require at least basic understanding of assembler coding wich is not easy or at least not for the average user I guess.

    No offense. But the average person cannot even read PNG format. Hackers have tools, like debuggers, that don't require source code. In fact, source code is hardly ever available to hackers; yet they do their job well. If you want to challenge your application, see if some hacking site will accept it. That's my opinion

    I'm not in any way questioning if it can be hacked or not. I used the most basic and elementary encription methods so it's obvious it can be hacked by professional hackers.
    I just wanted to see how easy it is to get around since most of you said it was so easy.

    Better idea it think. Posting a project on this site, PSC, or other code sites, and asking them to hack your app is a waste of your time. VB'ers may know how to code in VB, create executables, use executables. Some may even know a bit about what an executable looks like, and how it works, at the bit level, but a vast majority have no idea; nor do they care.

    This is the wrong place for such a "challenge". Kind of like a company sending their newest, greatest, CPU to the sales department and asking them to improve it's capabilities.

    Hello,

    Although your original source code is in VB6, your question doesn't really relate to VB6 at all. As a result, I am moving the thread to the Code It Better forum.
