KeySweeper is an open-source, open-hardware Arduino-based device disguised as a USB wall charger that passively sniffs, decrypts, and logs keystrokes from nearby Microsoft 2.4GHz wireless keyboards, exfiltrating them over GSM or flash storage. It includes schematics, firmware, and a web-based live keystroke monitoring tool.
Use cases
- sniff keystrokes from microsoft wireless keyboards
- build a hardware keylogger disguised as a usb charger
- demonstrate 2.4ghz rf keyboard vulnerabilities
- decrypt proprietary wireless keyboard protocols
- security research on wireless input devices
- physical pentest demonstration tooling
When to choose
- you need an open-hardware reference design for RF keyboard sniffing research
- you want to demonstrate risks of proprietary 2.4GHz wireless keyboards
- you're studying embedded SIGINT or hardware hacking techniques
When to avoid
- you need a software-only keylogger or endpoint monitoring solution
- you want a maintained product with support - last release was 2017
- your target keyboards use encrypted modern protocols rather than Microsoft's legacy 2.4GHz RF
- legal or ethical constraints prohibit covert surveillance devices
