The software which would listen to all the keystrokes made by the user is called
Answers
Answer:
Keystroke logging, often referred to as keylogging or keyboard capturing, is the action of recording (logging) the keys struck on a keyboard, typically covertly, so that person using the keyboard is unaware that their actions are being monitored. Data can then be retrieved by the person operating the logging program. A keylogger can be either software or hardware.
While the programs themselves are legal,[1] with many of them being designed to allow employers to oversee the use of their computers, keyloggers are most often used for stealing passwords and other confidential information.[2][3]
Keylogging can also be used to study human-computer interaction. Numerous keylogging methods exist: they range from hardware and software-based approaches to acoustic analysis.
Explanation:
Software-based keyloggers are computer programs designed to work on the target computer's software.[4] Keyloggers are used in IT organizations to troubleshoot technical problems with computers and business networks. Families and business people use keyloggers legally to monitor network usage without their users' direct knowledge. Even Microsoft publicly admitted that Windows 10 operation system has a built-in keylogger in its final version “to improve typing and writing services”.[5] However, malicious individuals can use keyloggers on public computers to steal passwords or credit card information. Most keyloggers are not stopped by HTTPS encryption because that only protects data in transit between computers, thus the threat being from the user's computer.
From a technical perspective, there are several categories:
Hypervisor-based: The keylogger can theoretically reside in a malware hypervisor running underneath the operating system, which thus remains untouched. It effectively becomes a virtual machine. Blue Pill is a conceptual example.
Kernel-based: A program on the machine obtains root access to hide in the OS and intercepts keystrokes that pass through the kernel. This method is difficult both to write and to combat. Such keyloggers reside at the kernel level, which makes them difficult to detect, especially for user-mode applications that don't have root access. They are frequently implemented as rootkits that subvert the operating system kernel to gain unauthorized access to the hardware. This makes them very powerful. A keylogger using this method can act as a keyboard device driver, for example, and thus gain access to any information typed on the keyboard as it goes to the operating system.
API-based: These keyloggers hook keyboard APIs inside a running application. The keylogger registers keystroke events as if it was a normal piece of the application instead of malware. The keylogger receives an event each time the user presses or releases a key. The keylogger simply records it.
Windows APIs such as
