It's the obfuscator (DeepSea) that added sealed to classes. It will still run it's just that no compiler would allow you to compile it. I'll add a de4dot option to remove sealed from classes in some future version.

BTW, if this was obfuscated with the commercial version, please PM me a link to the installer. The trial version never gets updated, and is always supported by de4dot.

0xd4d : Can you also make a documentation in a downloadable .chm help file format in your website? How about support deobfuscate the Confuser v1.9? Thank you.

You misunderstand me, i mean why 0xd4d don't also create a manual/help file with the release binary :)

Thank you very much for share, it's working great.

this is a very good tool..

Thank you very mutch
 

I hope this message finds you well with everything, I really appriciate your work that you have done on de4dot

I have a question when the protection is deteced as Eazfuscator.NET 3.3.149 - 3.4 what is the best way to run the de4dot with that parameters cause when i replace the cleaned dll it does not work.:(

can you send me that file on pm i want to try

Did someone contacted author?
looks like he is very busy.... (sent him already some reports but..)

Hey guys,

Is this project still alive? I was wondering if de4dot v2.0.4 or v.2.1 are in the works.

Several Obfuscators that have recently failed on me with v2.0.3 are:
Desaware QND Obfuscator
Crypto Obfuscator

The Desaware QND Obfuscated file was actually "cleaned" but not runnable. I may have to do some manual work on it...
But I was wondering if anyone already has a re-compiled version of de4dot that could "clean" a newer version of Crypto Obfuscated code.

Thanks!

I have checked this. Not working with new version Eazfuscator.NET. I hope de4dot fixes the issues.

the newest maxtocode is not supported

it is obvious that de4dot is out of the game,
it is the time to start learning thing by ourselves.

Using NET Internals and Code Injection Test MaxToCode can see most of the code il code, MaxTocode at runtime by vmp encrypted.

New version: 3.0.2
