"The researchers identified that it is possible for an attacking device to interfere with the procedure used to set up encryption on a BR/EDR connection between two devices in such a way as to reduce the length of the encryption key used," stated.This reduction in key length would make it much easier for an attacker to brute force the encryption key used by the paired devices to communicate with each other.Once the key was known to the attackers, they could monitor and manipulate the data being sent between the devices. Apple Blocks KNOB Attack on Bluetooth Researchers have discovered a serious security vulnerability that afflicts all Bluetooth devices. mechanisms of Bluetooth for any standard-compliant device. international team of researchers.

".The result: all Bluetooth-compliant devices are required to negotiate the length of the key they will use to encrypt the connection. Bluetooth specification.

As a result, the key encrypting the keystrokes and other sensitive data may be protected by a trivially crackable 1-byte key, with no easy way for a user to even know.The researchers—Daniele Antonioli of Singapore University of Technology and Design, Nils Ole Tippenhauer of CISPA Helmholtz Center for Information Security, and Kasper B. Rasmussen with the University of Oxford—have devised two attack variations to exploit these weaknesses.

The negotiation is also completely opaque to apps and OSes. Bluetooth communications might
standard provides security features to protect against A remote attacker can manipulate the entropy negotiation to let any standard compliant Bluetooth device negotiate encryption keys with 1 byte of entropy and then brute force the low entropy keys in real time.Bluetooth is a wireless communication protocol commonly used We BlackBerry and Google have announced …

KNOB targets and exploits a weakness in the firmware of a device’s Bluetooth chip that allows hackers to perform a Man-in-the-Middle (MiTM)attack via packet injection and disclose or leak potentially sensitive data. "It allows us to quickly test if a new device is vulnerable, and it was sufficient to demonstrate to the reviewers that the KNOB attack is a real, high-impact threat. 99.
This simple substitution works because LMP is neither encrypted nor integrity protected.
