    dotNet Protector v6.0.7180

    By VB56390

    Assemblies are obfuscated, then method bodies are replaced by corrupted code; de-compilation and disassembly tools like ILDASM can no more unassemble methods.
    Components Protection, this feature enables not only exe protection, but dll as well. ASP.Net is supported by dotNet Protector.
    Added anti-JIT.

    VirtualGuard v1.0

    By virtualguard

    This file is protected by the first version of VirtualGuard. VirtualGuard is an obfuscator I develop that I am trying to receive some stress testing on
    I hope this VM makes people think at least a little bit; It's fairly close to 1:1, however I do believe I do some interesting things with comparisons and branching. Haven't seen it anywhere else. Let the record state this is not a "mod" of any other vm, so if you are interested in seeing some new stuff this is for you.
    This sample contains some fairly simple branch offset mutations, at first glance it may be a slight "wtf moment" (at least I hope), but as soon as you figure out how the comparison system works it should be fairly easy to figure out.
    Anyways, enough of the kind-of hints. Would love any feedback on this. The crack-me element is fairly basic, just entering a password. Would definitely be a first step to solving though, so would like to see how people work on figuring that out.
    Good luck!

    NETBuilderInjection + VMP

    By DestroyerDarkNess

    I took my NETBuilderInjection and turned it into a Protector, but I don't know how secure it is. (For me, it's safe enough.)
    So I made this little program, The objectives are:
    [Unpackme] You should unpack it and get the cleanest code possible.
    [Crackme] In the textbox where the HWID is displayed you must modify the text and write something else in it.
    [Bypass] You will need to disable "Falcon Anticheat" from the executable.
    ----------------------------------------------------------------------------
    Difficulty : Unknown
    Language Base : .NET
    Platform : Windows - .NET Framework 4.6
    OS Version :  Windows 7 or higher.
    Packer / Protector : Improved NETBuilderInjection (in C) + VMP
    Description :
    NETBuilderInjection allows you to generate a Dll.NET assembly that can be easily injected into any process like any native dll. but in itself it is a packer. I made some improvements to it.
