What Is Keylogger?

The keyboard is your friend. Your best friend. But, wait… what's that? A keylogger? Keyloggers track and record successive keystrokes on a keyboard, and they are often dangerous. Keyloggers are frequently a part of malware, spyware, or an external virus. Because usernames and passwords, amongst other sensitive information, are usually entered on a keyboard, keyloggers are hazardous. If you ever feel like somebody is trying to hack into your life, you may want to invest in software that can detect and remove these malicious programs from your computer. There are many different keyloggers, but they all work the same way. Software keyloggers are stealthy little devils that infiltrate your computer in various ways. They can be built into rootkits or other less detectable forms and enter your computer in multiple ways. Hardware keyloggers are another kind of keylogger—they're based on electromagnetic emanations from hardware, which are addressed by emissions security protocols. A device can be fitted into a line between a keyboard and a device to act as a hardware keylogger. Keylogging is a big problem in the tech world, and it's only getting worse. Some new technologies are keylogger-resistant, despite keylogging being a persistent threat in many areas of the tech world. Because touch screen interfaces of mobile devices usually prevent conventional keyloggers from functioning, visual techniques like drop-down box choices can also defend against keyloggers if they have a secure data entry method. However, keylogging can be very effective in many cases and is becoming a severe issue for the average technology user. This issue is compounded by increasingly sophisticated malware that can infect your machine without your knowledge or consent. Once infected with malware, you could be vulnerable to malicious actions that could compromise your security or privacy—and even cause damage to other people's computers if you're connected to them over an insecure network like public Wi-Fi!
