Which keylogger category replaces the existing I/O driver with embedded keylogging functionality and sends keystrokes via the Internet?

• A. device driver keylogger
• B. Kernel keyloggers
• C. Bluetooth Keylogger
• D. Software Keystroke Loggers

Answer: (A)

Replacing the I/O driver with embedded keylogging functionality means the keylogger sits right in the keyboard input path, substituting the system’s own driver so every keystroke is captured as it flows from the hardware into the operating system. Because it’s integrated at that driver level, it can see all keystrokes and can easily send that data over the Internet to an attacker. This low-level position is what defines this category. Kernel keyloggers also work with input, but they don’t necessarily replace the I/O driver; they hook into kernel input handling while still relying on the system’s drivers. Bluetooth keyloggers involve capturing keystrokes from a Bluetooth device or using a wireless interceptor, not substituting the host’s input driver. Software keystroke loggers run in user space and log keys through APIs or hooks rather than replacing the I/O driver, so they don’t fit the described approach.
