The IoT Attack Vector “BlueBorne” Exposes Almost Every Connected Device



Armis Labs announced a new attack vector threatening major mobile, desktop, and IoT operating systems, including Android, iOS, Windows, and Linux, and the devices accepting them. The new vector is entitled “BlueBorne”, as it spread over the air (airborne) and initiatives media via Bluetooth. Armis should also unsealed eight reported zero-day vulnerabilities, four of which are named as critical. BlueBorne allows attackers to take control of devices, access corporate data and networks, penetrate secure “air-gapped” networks, and spread malware laterally to adjacent devices. Armis announced those vulnerabilities to the faithful performers and is operating with them as patches are being identified and released.

What Is New About BlueBorne?



A new airborne attack vector
BlueBorne concerns us because of the medium by which it operates. Unlike the majority of attacks today, which rely on the internet, a BlueBorne attack spreads through the air. This works correspondingly to the two abrupter general vulnerabilities found newly in a Broadcom Wi-Fi chip by Project Zero and Exodus. The vulnerabilities found in Wi-Fi chips affect only the peripherals of the device and require another step to take control of the device. By BlueBorne, criminals can gain full control right from the start. Moreover, Bluetooth offers a wider attacker surface than WiFi, almost entirely unexplored by the research community and hence contains far more vulnerabilities.

Airborne drives, badly, provide a number of events for the criminal. First, lying through the air does the attack many more taking, and allows it to flow with minimum effort. Second, it allows the attack to bypass current security measures and remain undetected, as traditional methods do not protect from airborne threats. Airborne attacks posterior further support hackers to enter protected internal networks which are “air-gapped,” implying they are detached from any other network for security. This can endanger industrial systems, government agencies, and critical infrastructure.

Ultimately, unlike common malware or attacks, the user arranges not hold to click on a link or download a suspicious file. No action by the user is required to enable the attack

What Is The Risk?


The Blue Borne attack vector has several qualities which can have a devastating effect when combined. By flowing into the air, BlueBorne targets the lightest place in the systems’ defense – and the only one that no security measure protects. Growing from device to device within the air also makes Blue Borne extremely dangerous. Moreover, considering the Bluetooth system has high chances on all operating systems, using it gives virtually full control over the device.

Regrettably, this set of capabilities is extremely desirable to a hacker. BlueBorne can better one serious goal, such as cyberspying, data theft, ransomware, and even creating large botnets out of IoT devices like the Mirai Botnet or mobile devices as with the recent WireX Botnet. The BlueBorne attack vector surpasses the capabilities of most attack vectors by penetrating secure “air-gapped” networks which are disconnected from any other network, including the internet.

How Wide Is The Threat?

The threat posed by the BlueBorne attack vector
The BlueBorne attack vector can potentially affect all devices with Bluetooth abilities, measured at over 8.2 billion devices now. Bluetooth is the best and most widespread protocol for short-range communications and is used by devices of all kinds, from regular computers and mobile devices to IoT devices such as TVs, watches, cars, and even medical appliances. The latest written opinions show more than 2 billion Android, 2 billion Windows, and 1 billion Apple devices in use. Gartner states that there are 8 billion related or IoT devices in the world today, many of which have Bluetooth.



A comprehensive and severe threat.


The BlueBorne attack vector requires no user interaction, is kind to all software releases, and does not need any preconditions or configurations aside of the Bluetooth is active. Unlike the common misconception, Bluetooth enabled devices are constantly searching for incoming connections from any devices, and not only those they have been paired with. That indicates a Bluetooth attachment can be installed outdoors joining the games at all. This makes BlueBorne one of the broadest potential attacks found in recent years and allows an attacker to strike completely undetected.

  What’s worst?

 All iOS devices including 9.3.5 or older stories and over 1.1 Billion current Android tools running older than Marshmallow (6.x) are vulnerable to the BlueBorne attack.

Moreover, millions of smart Bluetooth devices running a version of Linux are also vulnerable to the attack. Investment and consumer-oriented Linux policies (Tizen OS), BlueZ and 3.3-rc1 are also vulnerable to at least one of the BlueBorne bugs.

Android users need to wait for security patches for their devices, as it depends on your device manufacturers.

those meantime, everybody can install “BlueBorne Vulnerability Scanner” app (created by Armis team) of Google Play Store to verify if their devices are vulnerable to BlueBorne illness or not. If seen weak, you are encouraged to turn off Bluetooth on your device when not in use.
