How to Boost Database Development Productivity on Linux, Docker, and Kubernetes with Microsoft SQL Server 2. REGISTER What Is Key Logging Key logging, also known as keystroke logging or keyboard capturing, is the action of covertly recording the keys struck on a keyboard. Keylogging is also used to study human to computer interaction. OtQuLpEYUj0/0.jpg' alt='Code Program Notepad With Visual Basic' title='Code Program Notepad With Visual Basic' />Keyloggers also can be used to troubleshoot technical problems with computers and monitor network usage. Software based Keyloggers. Software based keyloggers are computer programs designed to work on the target computers software. These fall into several categories Windows APIs Windows APIs can be used to poll the state of the keyboard or to subscribe to keyboard events. Java. Script based Script tags get injected with malicious code on a targeted Web page, and listen for key events. Hypervisor based A keylogger resides in a malware hypervisor running underneath the operating system. Kernel based A program has obtained root access to the OS whilst it hides and and intercepts keystrokes. Download Free Programming Tools, Setup File Creators, Programming Editors, and more. Epson Stylus 6600. Chapter 2 Introduction to Visual Basic. NET In this chapter we begin learning about the fundamentals of programming and Visual Basic. NET. XAML Cruncher. XAML Cruncher lets you interactively type XAML code and see the object it creates. The program has all the features of Windows Notepad including File. Hardware based Keyloggers. These fall into several categories Keyboard hardware This can be a hardware circuit that is attached somewhere between the computer keyboard and the computer. Code Program Notepad With Visual Basic' title='Code Program Notepad With Visual Basic' />Firmware based BIOS level firmware that can handle keyboard events. Electromagnetic emissions You can capture electromagnetic emissions of a wired keyboard from up to 2. Wireless keyboard and mouse sniffers These sniffers collect packets of data being transferred from a wireless keyboard and its receiver. Keyboard overlays Device that gets placed on top of a keyboard on ATMs or similar devices to capture peoples PINs. Each keypress is registered by the keyboard of the ATM as well as the attached keypad overlay. Now that we know what types of keyloggers there are and how they work, you need to learn about the Windows API that I will use to demonstrate creating a very basic keylogger in Visual Basic. NET. Windows APIThe Windows API is a set of several hundred functions and subroutines that are located in a set of files called Dynamic Link Libraries DLLs. You can make a function from the Windows API available to your Visual Basic program by declaring the function to be callable from your program. You then can use the Windows API function as you would any built in Visual Basic function or a function that you have written yourself. Whenever possible, you should use managed code from the. NET Framework to perform tasks instead of Windows API calls. The advantage of using Windows APIs in your code is that they can save development time because they contain dozens of useful functions that are already written and waiting to be used. You can access the Windows API in Visual Basic. NET in two ways Declare statement. DLLImport. You can find more info on APIs here. Our Visual Basic Keylogger Project. Create a new Visual Basic Windows Forms project. You may name it anything you desire. Once the project has been created, add a Multiline Text. Box and a Timer to your Form. You can Enable the timer and set the interval to a relatively low amount. Figure 1 Design. The object of this project is to open Notepad and take whatever is typed inside the Text. Box and put it inside Notepad. Code. Add the following namespace declaration Imports System. Runtime. Interop. Services. The Interop. Services Namespace enables us to work with Windows APIs. Add the following variables Dim int. Key As Integer. Dim int. Proc. ID As Integer. Key represents the key that was pressed and int. Proc. ID represents the Process ID of the Notepad window we will work with a bit later. Add the following Windows API Public Declare Function Get. Async. Key. State Lib user. Alias Get. Async. Key. State By. Val v. Key As Integer. As Integer. The Get. Async. Key. State API determines whether a key is up or down at the time the function is called.

Lastly, it sends the key that was pressed to the Notepad window and appends it to the Text. Box, as shown in Figure 2. Figure 2 Our program in action. Please download the accompanying zip file. It contains the file needed to pursue this project. Conclusion. Keyloggers can be used for good purposes. Knowing the basics of how they are made can help set up proper security measures.
