How to protect my application that used ConfuserEx 0.5.0 avoid UnConfuserEx #221

hoavutinh commented 9 years ago

I have used ConfuserEx 0.5.0 to obfuscating my application, but when I use UnConfuserEx my application has deobfuscated eseasily.

Could I avoid that?

Just out of curiosity, Can you tell me where I can download "UnConfuserEx". I tried to google it but failed to find it.

This is link: https://forum.tuts4you.com/topic/36631-unconfuserex/ But you need to create account and sign in to see and download UnConfuserEx file

Hi, As stated by at the page, it does not fully defeat the protections provided by ConfuserEx. I'm looking to finding ways to improve protection strength.

As I stated in the tool's thread, UnConfuserEX can easily be useless, you only have to mod Antitamper and change some constant in the Decompress method.

@XenocodeRCE Could you please create a branch with an example of such modifications? I keep struggling to understand what to do exactly :crying_cat_face:

@xmx-1024 If you show me that you really tried to avoid UnconfuserEX to work with ConfuserEX 0.5 I may send you something. I don't trust in spoon-feeding

@XenocodeRCE I'd also be interested in seeing a branch with changes to help avoid UnConfuser as I to have had troubles changing the constants within ConfuserEx and having the obfuscation work properly.

XenocodeRCE commented 9 years ago

@Explicit-CB I won't do branch, because :

  1. I hate github and I can't manage to push a project from my computer
  2. It can be done within a few minutes.

For these lazy loony I made a Pull Request. If it's not accepted or whatever, I still made a Fork for this specified file (InvalidMetadataProtection.cs)
