I compiled my code and checked the exe file on the Virustotal website.

There is only one question left: will such software really be undetectable for antivirus programs? In my example, I used Visual Studio – you can use your favorite environment – to create such a keylogger in 30 minutes. Where the first expression (re) will match any email, and the second (re2) any digit of an alphabetic construction is greater than 6 characters. This is something like a mini-language for composing certain templates and scanning text for compliance with the given templates.įor simplicity, I will immediately give ready-made expressions that correspond to login names and passwords:1. It’s time to get familiar with regular expressions or regex.

Result: a huge file with gigabytes of text, in which the necessary information still needs to be found. Let’s also assume that he is ambitious enough and was able to infect tens or hundreds of thousands of cars. Let’s assume that the hacker was able to get the data with code like ours. The page title is stored in the buff variable, if it contains gmail or facebook, then the keyboard scan snippet is called.īy doing this, we ensured that the keyboard was scanned only when the browser window was open on facebook and gmail. This is done using the GetForegroundWindow function (more information on MSDN). This snippet will reveal an active window every 100ms. if (line.Contains (“Gmail”) || line.Contains (“Facebook – Log In or Sign Up”)) Now we constantly call this function to receive data from the keyboardħ. GetAsyncKeyState – This function determines whether a key was pressed or released at the time of the call and whether it was pressed after the previous call. To connect to the keyboard, you only need to use 2 lines in C #:ģ.public static extern int GetAsyncKeyState (Int32 i)

And finally, I will not talk about how to make a keylogger resistant to reboots or try to make it completely fingerless thanks to special programming techniques, as well as about protecting against deletion, even if it is found. Nevertheless, it is quite easy to program the basic functions of a keylogger.įurther, this code will not be optimized, I will just show you the lines of code that can accomplish the task, this is not the most elegant or optimal way. There are also hardware keyloggers, but they are less common because require direct physical access to the machine. Often this function is implemented in other, more complex software, for example, Trojans (Remote Access Trojans RATS), which ensure the delivery of intercepted data back to the attacker. Think of this as a digital trap for every keystroke on the keyboard. And all this is also free.Ī keylogger is software or some kind of physical device that can intercept and remember keystrokes on a compromised machine. Now i will tell and show you how to create your own keylogger that will not be detected by any of the existing antiviruses.
