So each window change event will be recorded. Here we need to know the active window and its title. But to record the currently active window, another hook is used.ĮVENT_SYSTEM_FOREGROUND helps us monitor active window change when WINEVENT_OUTOFCONTEXT shows that the callback method is in our application. The above-mentioned steps are enough for the keylogging feature. If the keys affecting the register are used, the symbol must be shifted to the uppercase. In the GetSymbol method, GetKeyboardLayout of the current window is requested, then ToUnicodeEx is requested to get the symbol. GetKeyState is another Win API method that can be used to learn the state. The SetKeysState method is used to know the state of extra keys, for instance, keys changing the register. To record the number of symbols, we need to implement the event with WM_KEYDOWN. This process records a symbol only after the key is up. In fact, iParam is a byte array so it stores extra data like the number of symbols if the user holds the key and the processing machine is slow. WParam is the event type (a key-down or key-up) NCode helps us understand whether we need to process the current event or convey it further Now let’s take a look at the method processing the hook. 0 is used so that the hook would be associated with all threads.

We’ll record the entered symbols at key-up events (WM_KEYUP).īelow, you can see the types for hooking a user’s shift from one window to another.Įnum for using hotkeys to exit the program. All other hooks (except WH_MOUSE_LL) require creating a separate DLL. To catch all the keyboard events, we will use WH_KEYBOARD_LL. Each type will be stored in separate Enum.

Now let’s look through several system code types that you’ll need while creating a keylogger for Windows.

Required Skills and knowledge: C#, as well as Win API and DACL Windows knowledge. The future keylogger will:īlock the process from a user without admin rights I’ll describe the system functions shortly, anyway, I recommend you to look through the official documents from Microsoft in advance. The following guide is written especially for the Dzone website and is based on blog articles of the Spyrix company that develops keyloggers and more complex monitoring software. Here I’m going to describe Windows programming methods you may find useful for developing a simple keylogger. Without further ado, let’s create the basic keylogging features on Windows.

Keyloggers can be integrated into more complex software like trojans that ensure the data delivery back to the attacker. There are also keyloggers that require physical access to the target computer but they are not widely used. Some keyloggers record the data in a hidden mode and transfer it to the spy via an online account. Always know your enemy:) Keyloggers - General InfoĪ keylogger is a tool collecting and recording all keystrokes from the target device. Can anybody with good programming skills become one of the “black hat coders”? I doubt it but I believe any IT security specialist should know several concepts that are used to create malicious software. The last group called “black hat coders” includes programming gurus writing the codes in a notebook and developing new exploits from scratch. Buyers are teenagers and other thrill-seekers who buy such malware on the Net and use it to collect and sell personal and financial data from target devices. The first group includes beginners who use well-known codes and utilities to create something resembling simple malicious software.

Hacker world can be contingently divided into three groups: the so-called “skids” (script kiddies), “buyers”, and “black hat coders”. Why Does an IT Security Specialist Need These Skills?
