KeyLlama records everything typed on a USB keyboard. Absolutely no software is required and KeyLlama is completely invisible to any software. The KeyLlama USB is the stealthiest hardware keylogger in existence - it is impossible to detect! Unlike many other keyloggers, these work with both low and full-speed USB Keyboards. Most newer USB keyboards operate at full-speed. Most lower cost keyloggers do not work with full-speed keyboards.
