Query: A Robust Algorithm for Sniffing BLE Long-Lived Connections in Real-time   Bluetooth Low Energy (BLE) has become an intrinsic wireless technology for
the Internet of Things (IoT). With the proliferation of BLE-embedded IoT
devices, it is important to study the security and privacy implications of BLE.
The forefront attack to BLE devices is the wireless sniffing attack, which
would lead to more detrimental threats like jamming, encryption cracking or
system penetration. Existing sniffing attacks are based on the correct
detection of BLE connection initiation state, but they become ineffective for
BLE long-lived connections. In this paper, we focus on the adversary setting
with a low-cost single radio and develop a suite of real-time algorithms to
determine the key parameters necessary to follow and sniff a BLE connection in
the connected state. We implement our algorithms in the open source platform
-Ubertooth One and evaluate its performance in terms of sniffing overhead and
accuracy. By comparing with state-of-the-art schemes, experimental results show
that our sniffer achieves much higher sniffing accuracy (over 80\%) and better
stability to BLE operational dynamics.
