Keyloggers are a type or hardware that records every keystroke on a computer’s keyboard. Hackers and cybercriminals often use it to gain sensitive information, such as credit card numbers and login credentials. Employers can use keystroke logging to track employee activity on company computers. Parents can use it to monitor their children’s online activities.
There are two types of keyloggers, software keyloggers or hardware keyloggers.
Software keyloggers are programs that run in the background on a computer, and record every keystroke on the keyboard. You can install them through malware such as viruses and Trojan horses or you can download them and have them installed by someone who has physical access to your computer. Software keyloggers can often be hidden and difficult to spot because they don’t appear in task manager or the list of programs installed.
Hardware keyloggers are physical devices that attach to the keyboard of the computer or plug into the USB port. These devices are small and easily concealed. Because they are powered by their own power source, hardware keyloggers can record keystrokes even if the computer is off. Because they don’t leave any trace on your computer’s hard drive, they are harder to spot than software keyloggers.
Once the keylogger has been installed, it starts recording every keystroke that is made on the keyboard. Login credentials, credit card numbers, and any other sensitive information are all recorded. This information is then stored in a log file that can be accessed only by the person who installed it. Some keyloggers allow you to send the log file to an email address or upload it remotely.
Keyloggers can be used in many ways to collect sensitive information. A hacker might install a keylogger on an open computer in a library, or at an internet cafe. Then, they would wait for someone to log in and provide sensitive information. This information would be recorded by the keylogger and sent to the hacker.
Keystroke logging can be used to track employee activity on company computers. Employers might install keyloggers in order to monitor employees’ productivity and to protect confidential information. Privacy concerns can arise from keyloggers being used in this manner. Employees may not be aware they are being watched.
Parents can use keystroke logging to monitor their children’s online activities. Parents can use this to ensure their children do not engage in inappropriate online behavior. Privacy concerns are raised, just like with keyloggers at work.
There are many ways to prevent keyloggers. To prevent keyloggers from being installed, you can use antivirus software and a firewall. It’s a good idea for online accounts to have strong passwords and use two-factor authentication when possible. It is also important to be careful when using public computers, and to be alert for suspicious activity.
A keylogger, in short, is any type of hardware or software that records every keystroke on a computer’s keyboard. Hackers and cybercriminals use it to collect sensitive information. However, employers can also use the keylogger to monitor employees’ activities or parents to monitor their children online. Keyloggers are difficult to spot and can cause privacy issues. It is essential to have a firewall and an antivirus system in place to protect yourself from keyloggers.
