PostSubject: How To Make Your Own Injector Using [VB6].   Wed Sep 25, 2013 5:14 am

Hello..Today Im Going To SHow you How To Make A Injecto In VB6

NOTE This Not Auto Inject...

--Caption-
Comman1 - &Browse
Comman2 - Inject Dll - Hotkey - Num Pad 0
Comman3 - B&rowse
Option1 - Exe Name
Option1 (Add A 2 Option And Name To 1) - Window Name
Label1 - Waiting....
Label2 - Injection Status:
Label3 - DLL Path:
Label4 - Process EXE name:
Text1 - None
Text2 - None


Now For The Code

Code:

Private Declare Function GetAsyncKeyState Lib "USER32" (ByVal vKey As Long) As Integer
Dim Content As String
Dim DllPath As String
Dim ExeName As Integer

Private Sub Command1_Click()
CommonDialog1.Filter = "Library|*.DLL"
CommonDialog1.ShowOpen
Text1.Text = CommonDialog1.FileName
Text1.SetFocus
End Sub

Private Sub Command2_Click()
If ExeName = 1 Then
    ProsH = GetHProcExe(Text2.Text)
        If ProsH = 0 Then Label1.Caption = "Cant find process!": Exit Sub
    DllPath = Text1.Text
    InjectDll DllPath, ProsH
Else
    ProsH = FindProc(Text2.Text)
        If ProsH = 0 Then Label1.Caption = "Cant find process!": Exit Sub
    DllPath = Text1.Text
    InjectDll DllPath, ProsH
End If
End Sub

Private Sub Command3_Click()
CommonDialog1.Filter = "Application|*.EXE"
CommonDialog1.ShowOpen
Text2.Text = CommonDialog1.FileTitle
Text2.SetFocus
End Sub

Private Sub Form_Load()
Option1(0).Value = True
Text2.Text = Load("HProcess", "Box2")
    If Text2.Text = Check Then Text2.Text = ""
Text1.Text = Load("DllPath", "Box1")
    If Text1.Text = Check Then Text1.Text = ""
End Sub

Private Sub Form_Unload(Cancel As Integer)
Call Save("HProcess", "Box2", Text2.Text)
Call Save("DllPath", "Box1", Text1.Text)
End Sub
Private Sub Option1_Click(Index As Integer)
Select Case Index
    Case 0
        Label4.Caption = "Process EXE name:"
        Command3.Enabled = True
        ExeName = 1
    Case 1
        Label4.Caption = "Process Window Name:"
        Command3.Enabled = False
        ExeName = 2
End Select
End Sub

Private Sub Timer1_Timer()
keyresult = GetAsyncKeyState(96)
    If keyresult = -32767 Then
        If ExeName = 1 Then
    ProsH = GetHProcExe(Text2.Text)
        If ProsH = 0 Then Label1.Caption = "Cant find process!": Exit Sub
    DllPath = Text1.Text
    InjectDll DllPath, ProsH
Else
    ProsH = FindProc(Text2.Text)
        If ProsH = 0 Then Label1.Caption = "Cant find process!": Exit Sub
    DllPath = Text1.Text
    InjectDll DllPath, ProsH
End If
    End If
End Sub
...So....

Add A 3 Module

And Change The Name To
Module1 - DllInjector
Module2 - modGetHProcExe
Module3 - SaveSets

...So Cleare All TXT In Module And The Code For Module

Modul1 Code

Code:

'VB DLL injector
'By Reckless Youth

'All the shit it takes to make VB to inject dlls...
Private Declare Function GetProcAddress Lib "kernel32" (ByVal hModule As Long, ByVal lpProcName As String) As Long
Private Declare Function GetModuleHandle Lib "kernel32" Alias "GetModuleHandleA" (ByVal lpModuleName As String) As Long
Private Declare Function LoadLibrary Lib "kernel32" Alias "LoadLibraryA" (ByVal lpLibFileName As String) As Long
Private Declare Function VirtualAllocEx Lib "kernel32" (ByVal hProcess As Long, lpAddress As Any, ByVal dwSize As Long, ByVal fAllocType As Long, FlProtect As Long) As Long
Public Declare Function WriteProcessMemory Lib "kernel32" (ByVal hProcess As Long, ByVal lpBaseAddress As Any, lpBuffer As Any, ByVal nSize As Long, lpNumberOfBytesWritten As Long) As Long
Private Declare Function CreateRemoteThread Lib "kernel32" (ByVal ProcessHandle As Long, lpThreadAttributes As Long, ByVal dwStackSize As Long, ByVal lpStartAddress As Any, ByVal lpParameter As Any, ByVal dwCreationFlags As Long, lpThreadID As Long) As Long
Public ProsH As Long

'The Injection Function
Public Function InjectDll(DllPath As String, ProsH As Long)
Dim DLLVirtLoc As Long, DllLength, Inject As Long, LibAddress As Long
Dim CreateThread As Long, ThreadID As Long

'STEP 1 -  The easy part...Putting the bitch in the process' memory
Form1.Label1.Caption = "Injecting......"
'Find a nice spot for your DLL to chill using VirtualAllocEx
DllLength = Len(DllPath)
DLLVirtLoc = VirtualAllocEx(ProsH, ByVal 0, DllLength, &H1000, ByVal &H4)
If DLLVirtLoc = 0 Then Form1.Label1.Caption = "VirtualAllocEx API failed!": Exit Function
'Inject the Dll into that spot
Inject = WriteProcessMemory(ProsH, DLLVirtLoc, ByVal DllPath, DllLength, vbNull)
If Inject = 0 Then Form1.Label1.Caption = "Failed to Write DLL to Process!"
Form1.Label1.Caption = "Dll Injected...Creating Thread....."


'STEP 2 - Loading it in the process
'This is where it gets a little interesting....
'Just throwing our Dll into the process isnt going to do shit unless you
'Load it into the precess address using LoadLibrary.  The LoadLibrary function
'maps the specified executable module into the address space of the
'calling process.  You call LoadLibrary by using CreateRemoteThread to
'create a thread(no shit) that runs in the address space of another process.
'First we find the LoadLibrary API function and store it
LibAddress = GetProcAddress(GetModuleHandle("kernel32.dll"), "LoadLibraryA")
If LibAddress = 0 Then Form1.Label1.Caption = "Can't find LoadLibrary API from kernel32.dll": Exit Function
'Next, the part the took me damn near 2 hours to figure out - using CreateRemoteThread
'We set a pointer to LoadLibrary(LibAddress) in our process, LoadLibrary then puts
'our Dll(DLLVirtLoc) into the process address.  Easy enough right?
CreateThread = CreateRemoteThread(ProsH, vbNull, 0, LibAddress, DLLVirtLoc, 0, ThreadID)
If CreateThread = 0 Then Form1.Label1.Caption = "Failed to Create Thead!"
Form1.Label1.Caption = "Dll Injection Successful!"
End Function
Now The For Module2 Cleare All TXT

Code:

'I DID NOT CREATE THIS MODULE!  Im in love with who ever did though  ;)
Public Const PROCESS_ALL_ACCESS As Long = &H1F0FFF

Option Explicit
Public Declare Function OpenProcess Lib "kernel32" (ByVal dwDesiredAccess As Long, ByVal bInheritHandle As Long, ByVal dwProcessId As Long) As Long
Public Declare Function FindWindow Lib "USER32" Alias "FindWindowA" (ByVal Classname As String, ByVal WindowName As String) As Long
Public Declare Function GetWindowThreadProcessId Lib "USER32" (ByVal hwnd As Long, lpdwProcessId As Long) As Long
Private Declare Function CreateToolhelpSnapshot Lib "kernel32" Alias "CreateToolhelp32Snapshot" (ByVal lFlags As Long, ByVal lProcessID As Long) As Long
Private Declare Function Process32First Lib "kernel32" (ByVal hSnapShot As Long, uProcess As PROCESSENTRY32) As Long
Private Declare Function Process32Next Lib "kernel32" (ByVal hSnapShot As Long, uProcess As PROCESSENTRY32) As Long
Private Declare Sub CloseHandle Lib "kernel32" (ByVal hPass As Long)


Private Type PROCESSENTRY32
    dwSize As Long
    cntUsage As Long
    th32ProcessID As Long
    th32DefaultHeapID As Long
    th32ModuleID As Long
    cntThreads As Long
    th32ParentProcessID As Long
    pcPriClassBase As Long
    dwFlags As Long
    szExeFile As String * 260
End Type

Public Function GetHProcExe(strExeName As String) As Long
Dim hSnap As Long
    'Create a snapshot of all of the processes, and information
    'about them (saving the handle so we can iterate through the
    'processes)
    hSnap = CreateToolhelpSnapshot(2, 0)
   
Dim peProcess As PROCESSENTRY32
    peProcess.dwSize = LenB(peProcess)
   
Dim nProcess As Long
    nProcess = Process32First(hSnap, peProcess)
   
    'Loop through the processes until we find the one we want
    'and return its process handle
    Do While nProcess
        If StrComp(Trim$(peProcess.szExeFile), strExeName, vbTextCompare) _
            = 0 Then
            GetHProcExe = OpenProcess(PROCESS_ALL_ACCESS, False, peProcess.th32ProcessID)
            Exit Function
        End If
        peProcess.szExeFile = vbNullString
        nProcess = Process32Next(hSnap, peProcess)
    Loop
    CloseHandle hSnap
End Function
Public Function FindProc(ProcName As String) As Long
Dim hwnd As Long
Dim ProcessID As Long
Dim ProcessHandle As Long
hwnd = FindWindow(vbNullString, ProcName)
GetWindowThreadProcessId hwnd, ProcessID
ProcessHandle = OpenProcess(PROCESS_ALL_ACCESS, False, ProcessID)
FindProc = ProcessHandle
End Function
...And The Last
Module3 Code Cleare All TXT

Code:

Declare Function WritePrivateProfileString Lib "kernel32" Alias "WritePrivateProfileStringA" (ByVal lpApplicationname As String, ByVal lpKeyName As Any, ByVal lsString As Any, ByVal lplFilename As String) As Long
Declare Function GetPrivateProfileString Lib "kernel32" Alias "GetPrivateProfileStringA" (ByVal lpApplicationname As String, ByVal lpKeyName As String, ByVal lpDefault As String, ByVal lpReturnedString As String, ByVal nSize As Long, ByVal lpFileName As String) As Long
Public Check As String

Public Function Load(Section As String, Key As String) As String
Dim lngResult As Long
Dim strFileName
Dim strResult As String * 300
strFileName = App.Path & "\sets.ini"
lngResult = GetPrivateProfileString(Section, Key, strFileName, strResult, Len(strResult), strFileName)
Check = App.Path & "\sets.ini"
Load = Trim(strResult)
End Function

Public Function Save(Section As String, Key As String, Content As String)
Dim lngResult As Long
Dim strFileName
strFileName = App.Path & "\sets.ini"
lngResult = WritePrivateProfileString(Section, Key, Content, strFileName)
End Function
So...Design Your Injector...And Make An EXE Your Injector

How To Make A EXE

1.Click The File
2.You See "Make Project.exe"
3.Name Your Project Example. "Injector.exe"
Import In The last ".exe"
