.NET Executable refers to a program file created using Microsoft’s .NET framework, typically with the extensions .exe or .dll. These executables contain Intermediate Language (IL) code, which is compiled by the .NET runtime (Common Language Runtime, or CLR) into machine code when the program is run. .NET executables are commonly used for Windows desktop applications, web services, and other software solutions. In cybersecurity, .NET executables can be analyzed for signs of malicious behavior, as attackers sometimes use the .NET framework to develop malware due to its flexibility and integration with Windows systems.
