A host of unpatched security bugs that allow BIAS attacks affects Bluetooth chips from Apple, Intel, Qualcomm, Samsung and others. Academic researchers have uncovered security vulnerabilities in Bluetooth Classic that allows attackers to spoof paired devices: They found that the bugs allow an attacker to insert a rogue device into an established Bluetooth pairing, masquerading as a trusted endpoint. This allows attackers to capture sensitive data from the other device. The bugs allow Bluetooth Impersonation Attacks (BIAS) on everything from internet of things (IoT) gadgets to phones to laptops, according to researchers at the École Polytechnique Fédérale de Lausanne (EPFL) in France. The flaws are not yet patched in the specification, though some affected vendors may have implemented workarounds. “We conducted BIAS attacks on more than 28 unique Bluetooth chips (by attacking 30 different devices),” the researchers said. “At the time of writing, we were able to test chips from Cypress, Qualcomm, Apple, Intel, Samsung and CSR. All devices that we tested were vulnerable to the BIAS attack.”
