Watch the console output. A successful unpack sequence will look like this:
Open ConfuserEx-Unpacker-2 (usually a command-line tool or a simple GUI) and load the protected file.
Assemblies containing both managed (.NET) and unmanaged (Native C++) code can disrupt the PE rebuilding engine, requiring manual post-processing fix-ups. confuserex-unpacker-2
Click or hit enter. The tool will parse the .NET assembly structure, locate the obfuscator's entry point, and begin stripping the modifications layer by layer.
For debugging purposes, a -vv (very verbose) parameter can be used to obtain detailed logging information, including: Watch the console output
For cases where automated unpackers fail—particularly with —manual deobfuscation techniques become necessary. These may involve:
(2023), proposes a system to automate the removal of protections applied by the ConfuserEx .NET obfuscator [DOI: 10.13089/JKIISC.2023.33.1.129]. Developed by researchers from Korea University and Naver Corporation, this tool focuses on defeating anti-debugging measures and simplifying obfuscated control flow to analyze malicious code [DOI: 10.13089/JKIISC.2023.33.1.129].

It transforms linear code into a complex web of switch statements and jumps.
