A Bluetooth vulnerability that could impact millions of users of smartphones, tablets and IoT devices was reported last week by two research groups. Researchers at Purdue University and the cole Polytechnique Fdrale de Lausanne in Switzerland said the exploit takes advantage of the Just Works security protocols first implemented with Bluetooth 4.0 that made it easier for an attacker to use brute force to break into a connection. The security measure has weak protection for authentication when two devices pair up. No patcheseither for firmware or operating system updatesare available yet to fix the problem.”]
