[VB.Net] Problem bei Signature Scanning

Hallo Freie-Häcker,
ich bin in Besitz eines erfreudigen Code-Schnipsels, mit dessen Hilfe man Memory-Signaturen (Byte-Pattern) suchen kann.

Rückgabewert ist, wenn eine Übereinstimmung gefunden worden ist, die erste Adresse.

Hier der Code (memory.vb; Modul):

Code:

---

Module memory
    Public Declare Function OpenProcess Lib "KERNEL32" _
    (ByVal DesiredAccess As Int32, _
    ByVal InheritHandle As Boolean, _
    ByVal ProcessId As Int32) _
    As Int32

    Private Declare Function ReadProcessMemory Lib "KERNEL32" _
    (ByVal Handle As Int32, _
    ByVal address As Int32, _
    ByRef Value As Int32, _
    Optional ByVal Size As Int32 = 4, _
    Optional ByVal lpNumberOfBytesWritten As Int64 = 0) _
    As Long

    Public PROCESS_VM_OPERATION As Int32 = 8
    Public PROCESS_VM_READ As Int32 = 16
    Public PROCESS_VM_WRITE As Int32 = 32

    Private process_id As Int32 = 0
    Public pHandle As Integer = 0

    Public Function GetProcessId(ByVal game_name As String) As Boolean
        Dim Processes() As Process = Process.GetProcesses
        Dim process_name As String
        Dim i As Byte
        For i = LBound(Processes) To UBound(Processes)
            process_name = Processes(i).ProcessName
            If process_name = game_name Then
                process_id = Processes(i).Id
                pHandle = OpenProcess(PROCESS_VM_OPERATION + PROCESS_VM_WRITE + PROCESS_VM_READ, False, process_id)
                Return True
            End If
        Next
        If process_id = 0 Then
            Return False
        End If
        Return False
    End Function

    Public Function ReadByte(ByVal address As Int32) As Integer
        Dim value As Integer
        ReadProcessMemory(pHandle, address, value, 1, 0)
        Return value
    End Function

    Public Function AOBSCAN(ByVal GameName As String, ByVal ModuleName As String, ByVal Signature As Byte()) As Integer
        Dim BaseAddress As Int32
        Dim EndAddress As Int32

        For Each PM As ProcessModule In Process.GetProcessesByName(GameName)(0).Modules
            If ModuleName = PM.ModuleName Then
                BaseAddress = PM.BaseAddress

                EndAddress = BaseAddress + PM.ModuleMemorySize


            End If
        Next
        Dim curAddr As Int32 = BaseAddress
        Do
            For i As Integer = 0 To Signature.Length - 1
                If ReadByte(curAddr + i) = Signature(i) Then
                    If i = Signature.Length - 1 Then
                        '  Form1.Label1.Text = curAddr.ToString("X")

                        MsgBox(curAddr.ToString("X"))
                        Return curAddr
                    End If
                    Continue For
                End If
                Exit For
            Next
            curAddr += 1
        Loop While curAddr < EndAddress
            Return 0
    End Function
End Module

Aufruf:

Code:

---

  If GetProcessId("GAME") = False Then
                Exit Sub
        Else : AOBSCAN("GAME", MODUL", New Byte() {&HAB, &HCD, &HEF, &H12, &H34, &H45})
        End If

---

So,
bei Modern Warfare 3 gibt es absolut keine Probleme. Meine Adresse wird gefunden:

Code:

---

If GetProcessId("iw5mp") = False Then
                      Exit Sub
        Else : AOBSCAN("iw5mp", "iw5mp.exe", New Byte() {&HAB, &HCD, &HEF, &H12, &H34, &H45})
        End If

---

Man beachte, dass das Modul bei MW3 auch "iw5mp.exe" heißt.

Mein Problem findet sich jetzt aber bei Counterstrike: Source:

Code:

---

  If GetProcessId("hl2") = False Then
                  Exit Sub
        Else : AOBSCAN("hl2", "client.dll", New Byte() {&HAB, &HCD, &HEF, &H12, &H34, &H45})
        End If

---

Die Adresse, die ich suche, befindet sich im Modul "client.dll".
Ich überprüfe das Byte-Array im Memory mit Cheat-Engine (auch extra geändert, um es einzigartig zu machen), und obwohl sie theoretisch einmal überienstimmten würden, findet das Programm nichts.

Meine Vermutung ist, dass es wohl an "client.dll" liegt.

Wenn jemand eine Lösung weiß, bin ich um jede Antwort dankbar!
