About this interactive

What you are doing: deciding whether each keylogger is hardware or software. The two kinds: a hardware keylogger is a physical device placed between the keyboard and the computer, or built into the keyboard. A basic one records keys on its own chip, so no software is installed and a scan finds nothing, but someone has to come back to collect it. (Some hardware models add Wi-Fi to send their logs out; every hardware card here is the basic kind.) A software keylogger is a program installed on the computer; it can save to a hidden file or send keystrokes over the network, which means an antivirus or endpoint tool might flag the program, and network monitoring might spot the data leaving. How to use it: ask whether it is a physical thing in the cable path or a program running on the machine. Sending data over the network is not the test on its own; the installed program is. A wrong answer resets your streak.
