It has been steadily increasing to use a wireless keyboard via Radio Frequency which is the input device. Especially, wireless keyboards that use 2.4 GHz frequency band are the most common items and their vulnerabilities have been reported since 2010. In this paper, we propose a 2.4 GHz wireless keyboard keystroke analysis and injection system based on the existing vulnerability researches of the Microsoft 2.4 GHz wireless keyboards. This system is possible to control on the remote. We also show that, via experiments using our proposed system, sensitive information of user can be revealed in the real world when using a 2.4 GHz wireless keyboard.
