John, an ethical hacker, is demonstrating a proof-of-concept IoT attack. For this demonstration, he used a jammer to jam and sniff the code sent by the car remote of a victim to unlock his car. Due to the jamming, the vehicle did not open; so the victim sent a code again to unlock his car. John sniffed the second code as well. After sniffing and capturing the second code, he forwarded the first code to the car which opened it. John can use the second code in future to unlock the car. What kind of attack did John demonstrate? Rolling Code Attack Side Channel Attack BlueBorne Attack Sybil Attack

If you're using a Bluetooth enabled device, whether it's a smartphone, laptop, smart TV, or any other IoT device, you risk malware attacks that can be remotely performed to take over your device, even without requiring any interaction from your side.

Security researchers have just discovered a total of 8 zero-day Bluetooth protocol vulnerabilities affecting more than 5.3 billion devices - from Android, iOS, Windows and Linux to the Internet of devices (IoT) - using technology short-range wireless communication

Using these vulnerabilities, security researchers at IoT security firm Armis created an attack, called BlueBorne, which could allow attackers to completely take over Bluetooth-enabled devices, spread malware, or even establish a “man” connection. -in-the-middle ”to gain access to device critical data and networks without requiring any victim interaction.
