This is the server program of the c# R.A.T. You will need to run this program on your computer, and not on the target's machine. The targets will connect to you with the help of this program. This is not a virus but serval AV will flag it as it's a virus. You need to build your own binary from this source code, so no trust issues. The executable is NOT published on this site, if you want the .exe you have to build the project using Visual Studio. The .dll files are published, because the project will not start without them. You need to select allow if the firewall prompt window come's up or the program can't open the TCP Server.
