TUTORIAL DE COMO SE FAZER UM INJETOR DE DLL HACKER

por **!-Felipe-!** Dom Fev 13 2011, 21:21

Aii vaii custei pra fazer mais ta aii::
Lembrando que é em Visual Basic 6

Vamos precisar de :
3 CommandButton
4 Label
1 Timer
2 TextBox
1 Microsoft Common Dialog Control 6.0
3 Module
2 Option

Vamos começar:
No Form Load declare o Seguinte código :
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 = ""

Feito isso vamos proceguir.

2° Adicione os CommandButton e dê o nome De :

Command1 = cmdInjetar
Command2 = cmdprocurar
Command3 = cmdprocurar2

Agora Adicione o Seguinte Código no "cmdInjetar"

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

Agora Adicione os Seguintes Códigos no "cmdprocurar"

CommonDialog1.Filter = "Application|*.EXE"
CommonDialog1.ShowOpen
Text2.Text = CommonDialog1.FileTitle
Text2.SetFocus

Agora os Códigos no "cmdprocurar2"

CommonDialog1.Filter = "Library|*.DLL"
CommonDialog1.ShowOpen
Text1.Text = CommonDialog1.FileName
Text1.SetFocus

Agora Adicione o Componente Microsoft Common Dialog Control 6.0 pressionando CTRL+T, e Declare o Segunte Código :

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

Agora feito isso Adicione um Timer e ponhe o seguinte código :

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

Agora Adicione as Label e dê o nome no Caption de "Processo.EXE" e "DLL Patch"

Adicione os 2 "Option" e para o "Option0" Mude o Nome do Caption para "Nome EXE" e ponhe o seguinte código:

Private Sub Option0_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

No "Option1" de o nome do Caption para "Nome da Janela" e adicione o código abaixo:

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

Declare também esse Código em Sua "Form"

Private Sub Form_Unload(Cancel As Integer)
Call Save("HProcess", "Box2", Text2.Text)
Call Save("DllPath", "Box1", Text1.Text)
End Sub

Adicione mais 2 Label e de o Nome do Caption para : "Status da Injeção" e "Esperando..."

Agora Adicione 3 Modules e renomeias para :

Module1 = DllInjector
Module2 = modGetHProcExe
Module3 = SaveSets

Adicione os seguintes Códigos no Module "DllInjector"

'VB DLL injector
'By RodrigoEviL

'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

'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

'maps the specified executable module into the address space of the

'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

No Module2 "modGetHProcExe" Adicione o Código:

No Module3 "SaveSets" Adicione :
