报告简介：

To defeat man-in-the-middle (MITM) and various other attacks, Bluetooth Low Energy (BLE) 4.2 and 5.x introduced the Secure Connections Only mode, under which a BLE device accepts only secure paring protocols including Passkey Entry and Numeric Comparison from an initiator such as an Android mobile. However, BLE does not have a similar Secure Connection Only mode for the initiator. We discover that the initiator should have enforced secure pairing too. If not, a spoofing BLE device can connect to the mobile device and perform various attacks against the mobile device through an app that connects to the BLE device. Based on our findings, the whole system with BLE apps and devices is deemed secure only if the secure pairing is enforced on both mobile devices and BLE devices. Various case studies and extensive experiments were performed to validate our findings. We have reported the BLE pairing vulnerability to the Google Android team and this vulnerability has received a High Severity rating (the corresponding patch is under active development by Google).
