This is the latest number of surveillance cameras, baby monitors, doorbells with webcams, and other internet connected devices found left open through two insecure communications protocols.
The peer-to-peer protocols are CS2 Network P2P, used by more than 50 million devices worldwide, and Shenzhen Yunni iLnkP2P, used by more than 3.6 million.
Internet-of-Things gadgets using vulnerable iLnkP2P implementations can be discovered and accessed by strangers, particularly if the default password has not been changed or is easily guessed.
