    Wanntabe Security Specialist

    Hi,


    I know there are decompliers out there for VB com object. .dll and .exe to to display the code and module. I also know that there are software out there to prevent the .dll from being decompile. Bascially, if anyone knows of a decomplier stopper please let me know. I also need this for .net as well.

    My goal is to not only to prevent hackers, but mainly my coworker (has admin access) who does not know how to code but steal my code and create projects and explains it to management that he can create projects like this as well. I really want to prevent this person for getting credit for my hard work. He's a hacker as well and knows how to break into .dll and .exe objects. Any advice on this is greatly appreicated.

    Thanks,

    Helpme

    First - welcome to VBF!
    And second - there are no decompilers for VB, attempts had been made but non of them really worked, though.
    Also, if you do develop at work and for that company you work for then ALL of your code entirely "belongs" to your company.

    As Rhino said I think you'll find that's not the case... COM modules can be freely viewed (e.g. the Object Browser in the VB IDE) but code can only be decompiled as far as assembly instructions. There is no way of getting the VB6 source code from an EXE.

    As for .NET, I hear there is a thing called Obfuscator... I think that's how it's spelt

    Re: Wanntabe Security Specialist

    Thanks guys for the response. But i do know that there are software, for example Reflection was a software i downloaded to decompile my asp.net .dll. It showed all of my functions.

    Also, i lost the links but if you guys search hard enough there are software out there (mainly foreign countries provided) that will decompile the .dll and .exe. I have a semi solution to my problem but i haven't tested it out yet. These guys had this problem, so this example should show you how to get it. Hopefully, i am wrong. This make me feel more secure with Microsoft it so.

    Well if its .Net there are some Obfuscator programs out there and there are several companies offering anti ILDasm and even one that compiles your program to native code.

    That pscode link won't really help you at all.

    Re: Wanntabe Security Specialist

    Is there anyway we can check to see if our application has been modified or accessed? A method to track down the hacker who got in and accessed the program, for instance their IP Address of their computer?

    Thanks,

    Well you can either do a checksum or an md5 hash of your program and see if it is different.
    Depends on where the application is located. If its on your server then your server may record the ipaddress of the person who accessed and changed the program.
