ConfuserEx is one of the most widely used open-source obfuscation tools for .NET applications. Developers use it to protect their intellectual property from reverse engineering. However, malware analysts, security researchers, and software developers often need to analyze these protected binaries.

Using confuserex-unpacker-2 alone is often not enough to fully restore an application. The general workflow for deobfuscating a ConfuserEx sample involves a layered approach.
The tool’s primary advantage is its use of an internal instruction emulator. This allows it to execute protected code segments in a controlled environment to determine their original state without needing to fully reverse-engineer every unique decryption algorithm. : Restoring strings and numeric constants hidden by
Methods filled with nested switch statements and local variables named with random symbols.
ConfuserEx-Unpacker-2, developed by KoiHook, is an open-source tool designed to reverse protections applied by ConfuserEx, including modern modded versions, by targeting constant decryption, control flow deobfuscation, and anti-tamper mechanisms [5, 11]. It employs dynamic analysis and the cawk-Emulator to unpack .NET binaries, making them readable for analysis when standard tools like de4dot fail [1, 5, 13].

Run the file in dnSpy's debugger. When the breakpoint hits, look at the locals or use the "Invert Call Stack" to read the decrypted plain-text strings directly from memory. B. Fixing Control Flow (Flattening)
