However, the concept of keystroke sniffing and injection was first made public by Thorsten Schroeder and Max Moser in 2010. Later, Travis Goodspeed published "Promiscuity is the nRF24L01+'s Duty," which expanded on the duo's work. In 2015, Samy Kamkar debuted KeySweeper, an Arduino-based USB wall charger designed to passively sniff and log keystrokes made by Microsoft keyboards.
Marc discovered that wireless mice and keyboards manufactured by AmazonBasics, Dell, Gigabyte, HP, Lenovo, Logitech, and Microsoft were all affected by many of the MouseJack vulnerabilities. An attacker with ..
