Serious Bluetooth flaw leaves devices open to attack
A group of researchers has discovered a critical Bluetooth vulnerability that leaves tons of wireless devices exposed to digital intrusions. The Bluetooth SIG, an organization that oversees the technology's standards, has issued a security notice for what the researchers are calling Key Negotiation of Bluetooth or KNOB attack. It gives bad actors the ability to interfere with the Bluetooth pairing procedure, allowing them to make the connection's encryption key shorter than what it's supposed to be. That makes it easy for attackers to brute force their way into the connection and be able to spy on data shared between devices, such as between a phone and a speaker or a phone and another phone.
