Executing Keyboard Injection Attacks

This report demonstrates a practical MouseJack-style vulnerability in Logitech Unifying wireless receivers that enables remote keyboard injection from a distance using inexpensive hardware (CrazyRadio) and the JackIt tool. The author reproduces payload injection to launch Notepad and to execute a cloud-hosted PowerShell script (IEX), outlines required hardware and payload syntax, notes Microsoft mitigation guidance, and recommends using wired/Bluetooth devices or firmware updates to reduce risk.
