After understanding the basic knowledge of control flow, this article will continue to introduce some methods for deobfuscating control flow obfuscation, and provide an example of a deobfuscator for ConfuserEx’s control flow obfuscation.

For some complex obfuscation techniques, control flow analysis is necessary to restore them. This article introduces the basic knowledge of .NET control flow analysis. Understanding these is enough to restore most obfuscations that require control flow analysis.
