Hi guys, I've been playing around with de4dot to see if SmartAssembly 6.8 offers any real protection against this deobfuscator, and unfortunately the answer seems to be no.

I used SmartAssembly 6.8 against our largest .NET assembly with 200,000+ lines of code with the highest levels of obfuscation available, and when inspected in .NET Reflector, the implementation code is not visible at all.

I then ran de4dot 2.03 against it, and I can now view the implementation in the cleaned assembly file using .NET Reflector, and the code is extremely close to the actual source code, taking the auto-generated compiler stuff into account.

This took me about 5 minutes and required very little technical knowledge - download, extract a zip, drag and drop a file onto an EXE, done.

Is there anything that can be done to block the effectiveness of this program?

The only defence is to ensure that all protections are added and added at their highest level.

Even with those settings, our program (130k+ lines of code) is easily reversed with the vital parts exposed!

Within a minute I was able to decipher internal passwords, logic and it resembled my code quite a bit again.

any news about this?
I will not be able to renew my subscription if redgate does not provide a solution to this problem.
