What Is A Keylogger?

Types Of Keyloggers

Well Keylogger Can Be Termed In Two Ways That Are As Follows

  • Hardware Keylogger – They Generally Record The Hardware Activities Of The Victim
  • Software Keylogger – They Can Be Used To Have A Full Control Over The Victims Data .

 

Well Today We Will Have A Brief Intro About The software Keyloggers as they are the most used in comparison with the hardware Keylogger. I would like to tell you that software keylogger can give the total data/info of the victim to you . you can also get the encrypted data too that means that whenever the victim will enter his/her account credentials than you will get that info too. the best part is that you could also bypass the OTP. Yeah you will also Get The OTP Code That is being received by the victim . so by this you must probably got what a keylogger can do .

Keylogger construction

The main idea behind keyloggers is to get in between any two links in the chain of events between when a key is pressed and when information about that keystroke is displayed on the monitor. This can be achieved using video surveillance, a hardware bug in the keyboard, wiring or the computer itself, intercepting input/ output, substituting the keyboard driver, the filter driver in the keyboard stack, intercepting kernel functions by any means possible (substituting addresses in system tables, splicing function code, etc.), intercepting DLL functions in user mode, and, finally, requesting information from the keyboard using standard documented methods.




Experience shows that the more complex the approach, the less likely it is to be used in common Trojan programs and the more likely it is to be used in specially designed Trojan programs which are designed to steal financial data from a specific company.

Keyloggers can be divided into two categories: keylogging devices and keylogging software. Keyloggers which fall into the first category are usually small devices that can be fixed to the keyboard, or placed within a cable or the computer itself. The keylogging software category is made up of dedicated programs designed to track and log keystrokes.

The most common methods used to construct keylogging software are as follows:

  • a system hook which intercepts notification that a key has been pressed (installed using WinAPI SetWindowsHook for messages sent by the window procedure. It is most often written in C);
  • a cyclical information keyboard request from the keyboard (using WinAPI Get(Async)KeyState or GetKeyboardState – most often written in Visual Basic, sometimes in Borland Delphi);
  • using a filter driver (requires specialized knowledge and is written in C).

We will provide a detailed explanation of the different ways keyloggers are constructed in the second half of this article (to be published in the near future). But first, here are some statistics.

A rough breakdown of the different types of keyloggers is shown in the pie chart below:

Recently, keyloggers that disguise their files to keep them from being found manually or by an antivirus program have become more numerous. These stealth techniques are called rootkit technologies. There are two main rootkit technologies used by keyloggers:

  • masking in user mode;
  • masking in kernel mode.

A rough breakdown of the techniques used by keyloggers to mask their activity is shown in the pie chart below:
