Bluetooth is used worldwide as one of the most convenient methods of connecting and controlling connected devices. However, according to a recent report, one has been identified vulnerability under the brand name KNOB (Key Negotiation of Bluetooth) on Bluetooth connections.
All Bluetooth compatible devices can be affected by vulnerability, which allows attackers to spy on a victim's personal conversations. The hackers they can also take advantage of the vulnerability to steal data on the compromised device.
When creating a Bluetooth connection, both devices are based on one encryption key. Hackers in order to carry out the attack exploit the vulnerability in the Bluetooth standard and weaken this encryption instead of disabling it immediately.
Vulnerability affects devices from some of the most well known manufacturers, in particular Apple, Qualcomm and Intel. Companies such as Apple, Microsoft, Microsoft CiscoThe Google, Blackberry, Broadcom and Chicony have already released a patch to fix the bug, according to reports Mashable.
The team of researchers from the University of Technology and Design in Singapore, the University of Oxford and the CISPA Helmholtz Information Center, who found this critical vulnerability, explained:
"We found a serious vulnerability in Bluetooth that allows an intruder to break his security mechanisms for any device that is compatible with the standard. As a result, the intruder can hear or change the content of the communication via Bluetoth even among devices that have previously been successfully combined. "
