Managed DLL Exports and run via rundll32
Hello All, Security landscape is changing very quickly wherein security researchers have to be more dynamic and innovative to improve the security posture of the organizations. In this post I will cover the concept on how we can develop a DLL with exported function in C#. Note:- I am not the first person to develop this tool or technique.
