Bluetooth BIAS Attacks

May 18, 2020

In 2020 we disclosed the Bluetooth Impersonation AttackS (BIAS), a family of high impact attacks affecting Bluetooth’s authentication protocols. The attacks allow impersonating any Bluetooth device during secure session establishment without knowing the long term pairing key. The BIAS attacks are tracked with CVE-2019-9506

On the (In)securities of Popular Standard and Proprietary Wireless Protocols
This talk covers our recent research on the (in)securities of proprietary and standard wireless security protocols used daily by millions of devices and users. In particular, I will cover the BLUR attacks on Bluetooth, a novel class of threats capable of exploiting Bluetooth Classic from Bluetooth Low Energy and vice versa.

BIAS and KNOB attacks against Bluetooth BR/EDR/LE
Bluetooth is a ubiquitous technology for low power wireless communications. Bluetooth runs on billions of devices including mobile, wearables, home automation, smart speakers, headsets, industrial and medical appliances, and vehicles. As a result, Bluetooth’s attack surface is huge and includes significant threats such as identity thefts, privacy violations, and malicious device control.
