are they pressed or not) every N milliseconds and records the pressed keys in a special log. Therefore, the algorithm is as follows: we check the status of all keys (i.e. GetAsyncKeyState determines whether a key is pressed or not at the time of the call and whether the key was pressed after a previous call to that function. If we cannot do this (for instance, the SetWindowsHookEx function is restricted by the antivirus), it is possible to get raw keyboard input in a different way. Therefore, the easiest way to intercept the keyboard input is to receive keypress notifications. When you press a key, the operation notifies programs that are registered to intercept keyboard events. However, this not-so-elegant version gives better results when checked by antivirus apps so, I am going to describe it, too. Leaping ahead, I must say that I got two versions of the program: the first one intercepts WinAPI calls, while the second one is a more of a mockup. We will write the keylogger in C# using Visual Studio. Therefore, we should monitor the clipboard contents as well. If the victim uses a password manager, the keystroke log would only contain some Ctrl-C and Ctrl-V sequences. We won’t try to conceal the process – just give it an unsuspicious name.The firewall is taken out of the equation: we will give it the required permission manually while planting the keylogger and.The antivirus must not ring alarm bells.We are connected to the same LAN and will use that connection to retrieve the logs.We can access the target computer only once and for a short duration of time.We do not want to alert the victim by additional windows, taskbar icons, error messages, etc.Let us say, we want to obtain the password to the victim’s VK profile, and can momentarily secure physical access to the target computer. In this article, I will explain how to do this concurrently, we will practice our C# coding skills. However, it is not that difficult to create a homemade keylogger and avoid antivirus alerts. Commercial keyloggers supporting numerous functions and protected against detection may cost dozens and even hundreds of dollars.
