How do disassemble/decompile ConfuserEx 0.5 DLL


myli

Recommended Posts

Hello,


 


i've a question. Ive a DLL (yes, i know the source) which is confused using ConfuserEx 0.5 with .NET Framework 4.52.


 


 


Now i've tried to to open the DLL using several disassembler but no result. I found several tutorials how to unconfuse the DLL in this forum but all of them are not successfully in this case.


 


 


Ive tried ConfuserExFixer, MethodsDecrypter, ... and so on.


 


could anyone tell me HOW it's possible and a decrypted result?


 


Attached is the DLL. Its nothing special. Thanks.

Besides breaking the DLL, maybe it's restored enough information for you to go through the DLL to see where the interesting stuff happens. Then using the Token of the method of interest, you can get to work in the original DLL's method.


 


You probably can open the DLL just find in dnSpy, it seems to be quite tolerant to bad metadata.

Can you give a tutorial for unpack the DLL packed with confuser 0.5 custom? Thanks
