[Source] How to make a DLL injector in VB

[scimmyboy]

Well, since not many ppl read the VB section, might as well post it here.

So....here's the source code

Public Class Form1

    Private TargetProcessHandle As Integer
    Private pfnStartAddr As Integer
    Private pszLibFileRemote As String
    Private TargetBufferSize As Integer

    Public Const PROCESS_VM_READ = &H10
    Public Const TH32CS_SNAPPROCESS = &H2
    Public Const MEM_COMMIT = 4096
    Public Const PAGE_READWRITE = 4
    Public Const PROCESS_CREATE_THREAD = (&H2)
    Public Const PROCESS_VM_OPERATION = (&H8)
    Public Const PROCESS_VM_WRITE = (&H20)

    Public Declare Function ReadProcessMemory Lib "kernel32" ( _
    ByVal hProcess As Integer, _
    ByVal lpBaseAddress As Integer, _
    ByVal lpBuffer As String, _
    ByVal nSize As Integer, _
    ByRef lpNumberOfBytesWritten As Integer) As Integer

    Public Declare Function LoadLibrary Lib "kernel32" Alias "LoadLibraryA" ( _
    ByVal lpLibFileName As String) As Integer

    Public Declare Function VirtualAllocEx Lib "kernel32" ( _
    ByVal hProcess As Integer, _
    ByVal lpAddress As Integer, _
    ByVal dwSize As Integer, _
    ByVal flAllocationType As Integer, _
    ByVal flProtect As Integer) As Integer

    Public Declare Function WriteProcessMemory Lib "kernel32" ( _
    ByVal hProcess As Integer, _
    ByVal lpBaseAddress As Integer, _
    ByVal lpBuffer As String, _
    ByVal nSize As Integer, _
    ByRef lpNumberOfBytesWritten As Integer) As Integer

    Public Declare Function GetProcAddress Lib "kernel32" ( _

    Private Declare Function GetModuleHandle Lib "Kernel32" Alias "GetModuleHandleA" ( _

    Public Declare Function CreateRemoteThread Lib "kernel32" ( _
    ByVal hProcess As Integer, _
    ByVal lpThreadAttributes As Integer, _
    ByVal dwStackSize As Integer, _
    ByVal lpStartAddress As Integer, _
    ByVal lpParameter As Integer, _
    ByVal dwCreationFlags As Integer, _
    ByRef lpThreadId As Integer) As Integer

    Public Declare Function OpenProcess Lib "kernel32" ( _
    ByVal dwDesiredAccess As Integer, _
    ByVal bInheritHandle As Integer, _
    ByVal dwProcessId As Integer) As Integer

    Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" ( _
    ByVal lpClassName As String, _
    ByVal lpWindowName As String) As Integer

    Private Declare Function CloseHandle Lib "kernel32" Alias "CloseHandleA" ( _
    ByVal hObject As Integer) As Integer


    Dim ExeName As String = IO.Path.GetFileNameWithoutExtension(Application.ExecutablePath)

    Private Sub Inject()
        On Error GoTo 1 ' If error occurs, app will close without any error messages
        Timer1.Stop()
        Dim TargetProcess As Process() = Process.GetProcessesByName("WarRock")
        TargetProcessHandle = OpenProcess(PROCESS_CREATE_THREAD Or PROCESS_VM_OPERATION Or PROCESS_VM_WRITE, False, TargetProcess(0).Id)
        pszLibFileRemote = Application.StartupPath & "\" + ExeName + ".dll"
        pfnStartAddr = GetProcAddress(GetModuleHandle("Kernel32"), "LoadLibraryA")
        TargetBufferSize = 1 + Len(pszLibFileRemote)
        Dim Rtn As Integer
        Dim LoadLibParamAdr As Integer
        LoadLibParamAdr = VirtualAllocEx(TargetProcessHandle, 0, TargetBufferSize, MEM_COMMIT, PAGE_READWRITE)
        Rtn = WriteProcessMemory(TargetProcessHandle, LoadLibParamAdr, pszLibFileRemote, TargetBufferSize, 0)
        CreateRemoteThread(TargetProcessHandle, 0, 0, pfnStartAddr, LoadLibParamAdr, 0, 0)
        CloseHandle(TargetProcessHandle)
1:      Me.Close()
    End Sub

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        If IO.File.Exists(Application.StartupPath & "\" + ExeName + ".dll") Then
            Dim TargetProcess As Process() = Process.GetProcessesByName("HSUpdate")
            If TargetProcess.Length = 0 Then
                Me.TextBox1.Text = ("Waiting for Warrock.exe")
                Me.TextBox2.Text = ("Let´s Hack")
            Else
                Timer1.Stop()
                Me.TextBox1.Text = "Done..."
                Call Inject()
            End If
        Else
            Me.TextBox1.Text = ("" + ExeName + ".dll not found")
            Me.TextBox2.Text = ("Rename the .dll To " + "" + ExeName)
        End If
    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Timer1.Interval = 50
        Timer1.Start()
    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        MsgBox("Thats the Status Box!", MsgBoxStyle.Information, "Info")
    End Sub
End Class

this is just a basic injector, so no protection against any anti-hack game detection system

This is xTmx/Miwin/Maplester's original, just adapted for Warrock. If this CHOOB had used the search, he would see that xTmx already posted it.

[dean-wingess]

its patched nerds!

[Zoom]

No it´s not patched, it just need some bug fixes! C&P wont work choobs

[BARON]

Not off google, off youtube!

LOL VB Injectors Get Patched Fast Anyway..People Should make more Injectors Made By C++!

[SpaceMan]

I dont think he's a CHOOB yo....

I Have definitely seen this code on youtube and off of google..

Way to copy + paste w/o credits

[martijno0o0]

its posted so much times, and it even isnt work, it ain't injecting

[zmansquared]

I got it to work. had to change things first

[Samueldo]

If VB injectors get patched fast how come my InjectPlz series is still working? You just need to run as admin.
