Sorry for the silly question, but the slides seemed to indicate that any USB keyboard can read any other keyboard's keystrokes? Is that a correct understanding?

Sorry for the silly question, but the slides seemed to indicate that any USB keyboard can read any other keyboard's keystrokes? Is that a correct understanding? Otherwise, I don't see how they can steal passwords. Am I just missing something obvious?
- tedunangst 12y agoTheir evil keyboard runs commands to install malware which capture your password when later entered on the good keyboard. i.e. Their keyboard types "install keylogger".
- cnvogel 12y agoNo, USB keyboards (or mice) can't. That's why some keyloggers use a certain sequence of capslock/numlock/scroll-lock presses to trigger output of a menu or the stored data: The status of the corresponding LEDs is the only information a PC sends to a keyboard.
