Researchers have demonstrated a serious weakness in Bluetooth standard that could allow hackers to intercept keystrokes, address books, and other sensitive data from billion of devices.
KNOB doesn't require an attacker to have any previously shared secret material or to observe the pairing process of the targeted devices. The exploit is invisible to Bluetooth apps and the operating systems they run on, making the attack almost impossible to detect without highly specialised equipment.
The attack forces two or more devices to chose an encryption key just a single byte in length before establishing a Bluetooth Connection. Attackers within radio range can use commodity hardware to quickly crack the key. From there, attackers can use the cracked key to decrypt data passing between the devices.
