Which keylogger replaces the existing I/O driver with embedded logging and sends the keystrokes to a destination via the Internet?

• A. Application Keylogger
• B. Bluetooth Keylogger
• C. Acoustic/CAM Keylogger
• D. device driver keylogger

Answer: (D)

The key concept here is intercepting keystrokes at the kernel level by replacing the keyboard I/O driver with one that logs every keystroke as it moves through the input stack, then sending those logs to a remote destination over the Internet. This driver-level approach sits directly in the input path, capturing keystrokes before they reach applications, making the logging stealthy and persistent since it operates below user-space detection and can survive typical security checks that focus on user-mode activity. The embedded logging records the exact sequence of keys and can exfiltrate them remotely, which is why this method is described as replacing the I/O driver with embedded logging and transmitting the data over the network. In contrast, an application keylogger runs in user space by hooking into OS-provided input events or APIs, which is generally easier to detect and can be limited to specific applications. A Bluetooth keylogger targets data transmitted over Bluetooth and may require a separate device or module to capture those transmissions, rather than replacing the system’s I/O driver. An acoustic or CAM keylogger uses sound or visual cues to infer keystrokes rather than intercepting the actual input path.
