Also, until we have created a form (and we will not create it), no icons will appear in the taskbar - an important part of the hidden work. Why Windows Forms? If we choose a regular console application, then an ugly black window will be created every time it starts, and we agreed not to bother the user. Writing the codeFirst, let's open Visual Studio and create a new Windows Forms (.NET Framework) project. We will write the received data to a file. Then we process the list, taking into account the state of the Caps Lock, Num Lock, Shift, Ctrl and so on. Actually, the algorithm of actions will be as follows: every N ms we interrogate all the buttons and find out their state by entering the pressed ones into a special list.
There is such a function - GetAsyncKeyState, which takes a key number and allows you to find out whether it is pressed or released at the time of the call. If we cannot do this (for example, the SetWindowsHookEx function is prohibited by antivirus or something else), we can pull raw input without it. Therefore, the easiest way to intercept keyboard input is to receive keystroke messages. TheoryWhen you press a button, the operating system sends notifications to those programs that want to know about it. But this less beautiful version gives different results when scanned by antiviruses, so I'll tell you about it as well. Looking ahead, I will say that as a result I got two versions of the program - one works through the interception of WinAPI, the other I call myself a "crutch". In this case, we will also monitor the contents of the clipboard.
#PUNTO SWITCHER KEYLOGGER PASSWORD#
The victim can also use the password manager, then in the log we will only get Ctrl-C and Ctrl-V. we will not try to hide the process and will only give it an inconspicuous name.we do not take into account the firewall and assume that we will give it permission manually when the keylogger is planted.we will be able to collect logs from the same local network.we have access to the target computer only once and for a very short time.we do not bother the victim with unnecessary windows, icons in the taskbar, error messages and the like.Suppose we want to get the victim's password from VK and we can briefly gain physical access to the computer. We set the taskWe will not be wise and restrict ourselves to the necessary minimum.
#PUNTO SWITCHER KEYLOGGER HOW TO#
In this article I will show you how to do this, and at the same time we will practice developing programs in C #. But a keylogger is not such a complicated thing, and if you wish, you can make your own and even avoid being detected by antiviruses. Combat keyloggers with tons of features and anti-detection protection can cost tens, if not hundreds of dollars.
