A Dozen Vulnerabilities Affect Millions of Bluetooth LE Powered Devices

A Dozen Vulnerabilities Affect Millions of Bluetooth LE Powered Devices

February 17, 2020Wang Wei
A team of cybersecurity researchers late last week disclosed the existence of 12 potentially severe security vulnerabilities, collectively named ' SweynTooth ,' affecting millions of Bluetooth-enabled wireless smart devices worldwide—and worryingly, a few of which haven't yet been patched. All SweynTooth flaws basically reside in the way software development kits (SDKs) used by multiple system-on-a-chip (SoC) have implemented Bluetooth Low Energy (BLE) wireless communication technology—powering at least 480 distinct products from several vendors including Samsung, FitBit and Xiaomi. According to the researchers, hackers in close physical proximity to vulnerable devices can abuse this vulnerability to remotely trigger deadlocks, crashes, and even bypass security in BLE products, allowing them to arbitrary read or write access to device's functions that are otherwise only allowed to be accessed by an authorized user. "As of today, SweynTooth vulnerabilities a

New Bluetooth Vulnerability Lets Attackers Spy On Encrypted Connections

Over a billion Bluetooth-enabled devices, including smartphones, laptops, smart IoT devices, and industrial devices, have been found vulnerable to a high severity vulnerability that could allow attackers to spy on data transmitted between the two devices. The vulnerability, assigned as CVE-2019-9506 , resides in the way 'encryption key negotiation protocol' lets two Bluetooth BR/EDR devices choose an entropy value for encryption keys while pairing to secure their connection. Referred to as the Key Negotiation of Bluetooth ( KNOB ) attack, the vulnerability could allow remote attackers in close proximity to targeted devices to intercept, monitor, or manipulate encrypted Bluetooth traffic between two paired devices. The Bluetooth BR/EDR (Basic Rate/Enhanced Data Rate, also known as "Bluetooth Classic") is a wireless technology standard that has typically been designed for relatively short-range, continuous wireless connection such as streaming audio to headsets

Security researchers have unveiled details of two critical vulnerabilities in Bluetooth Low Energy (BLE) chips embedded in millions of access points and networking devices used by enterprises around the world. Dubbed BleedingBit , the set of two vulnerabilities could allow remote attackers to execute arbitrary code and take full control of vulnerable devices without authentication, including medical devices such as insulin pumps and pacemakers, as well as point-of-sales and IoT devices. Discovered by researchers at Israeli security firm Armis, the vulnerabilities exist in Bluetooth Low Energy (BLE) Stack chips made by Texas Instruments (TI) that are being used by Cisco, Meraki, and Aruba in their enterprise line of products. Armis is the same security firm that last year discovered BlueBorne , a set of nine zero-day Bluetooth-related flaws in Android, Windows, Linux and iOS that affected billions of devices, including smartphones, laptops, TVs, watches and automobile audio sy

Yet another bluetooth hacking technique has been uncovered. A highly critical cryptographic vulnerability has been found affecting some Bluetooth implementations that could allow an unauthenticated, remote attacker in physical proximity of targeted devices to intercept, monitor or manipulate the traffic they exchange. The Bluetooth hacking vulnerability, tracked as CVE-2018-5383, affects firmware or operating system software drivers from some major vendors including Apple, Broadcom, Intel, and Qualcomm, while the implication of the bug on Google, Android and Linux are still unknown. The security vulnerability is related to two Bluetooth features—Bluetooth low energy (LE) implementations of Secure Connections Pairing in operating system software, and BR/EDR implementations of Secure Simple Pairing in device firmware. How the Bluetooth Hack Works? Researchers from the Israel Institute of Technology discovered that the Bluetooth specification recommends, but does not mandate

Remember BlueBorne? A series of recently disclosed critical Bluetooth flaws that affect billions of Android, iOS, Windows and Linux devices have now been discovered in millions of AI-based voice-activated personal assistants, including Google Home and Amazon Echo . As estimated during the discovery of this devastating threat, several IoT and smart devices whose operating systems are often updated less frequently than smartphones and desktops are also vulnerable to BlueBorne. BlueBorne is the name given to the sophisticated attack exploiting a total of eight Bluetooth implementation vulnerabilities that allow attackers within the range of the targeted devices to run malicious code, steal sensitive information, take complete control, and launch man-in-the-middle attacks. What's worse? Triggering the BlueBorne exploit doesn't require victims to click any link or open any file—all without requiring user interaction. Also, most security products would likely not be abl

BlueBorne: Critical Bluetooth Attack Puts Billions of Devices at Risk of Hacking

If you are using a Bluetooth enabled device, be it a smartphone, laptop, smart TV or any other IoT device, you are at risk of malware attacks that can carry out remotely to take over your device even without requiring any interaction from your side. Security researchers have just discovered total 8 zero-day vulnerabilities in Bluetooth protocol that impact more than 5.3 Billion devices—from Android, iOS, Windows and Linux to the Internet of things (IoT) devices—using the short-range wireless communication technology. Using these vulnerabilities, security researchers at IoT security firm Armis have devised an attack, dubbed BlueBorne , which could allow attackers to completely take over Bluetooth-enabled devices, spread malware, or even establish a "man-in-the-middle" connection to gain access to devices' critical data and networks without requiring any victim interaction. All an attacker need is for the victim's device to have Bluetooth turned on and obvious

Bluetooth Low Energy, also known as Bluetooth Smart or Bluetooth 4, is the leading protocol designed for connecting IoT devices, medical equipment, smart homes and like most emerging technologies, security is often an afterthought. As devices become more and more embedded in our daily lives, vulnerabilities have real impact on our digital and physical security. Enter the Bluetooth lock, promising digital key convenience with temporary and Internet shareable access. The problem is, almost all of these locks have vulnerabilities, easily exploited via Bluetooth! DEF CON always has the coolest new hacks and security news, and this year was no exception. The hacking conferences are a great way to get a pulse on the general status of the security world, what people are interested in, worried about, or looking to exploit. This year clearly had an uptick in Internet of Things (IoT) devices and ways to hack them. Obviously, we had to go and take a look at the Bluetooth lock hack, and
