Armis Labs revealed a new attack vector endangering major mobile, desktop, and IoT operating systems, including Android, iOS, Windows, and Linux, and the devices using them. The new vector is dubbed “BlueBorne”, as it spread through the air (airborne) and attacks devices via Bluetooth. Armis has also disclosed eight related zero-day
vulnerabilities, four of which are classified 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 reported these vulnerabilities to the responsible actors, and is working with them as patches are being identified and released.
Bluetooth is a difficult protocol to implement, which makes it prone to two kinds of vulnerabilities. On the one hand, vendors are likely to follow the protocol’s implementation guidelines word-for-word, which means that when a vulnerability is found in one platform it might affect others. These mirrored vulnerabilities happened with CVE-2017-8628 and CVE-2017-0783 (Windows & Android MiTM) which are “identical twins”. On the other hand, in some areas the Bluetooth specifications leave too much room for interpretation, causing fragmented methods of implementation in the various platforms, making each of them more likely to contain a vulnerability of its own.
All Android phones, tablets, and wearables (except those using only Bluetooth Low Energy) of all versions are affected by four vulnerabilities found in the Android operating system, two of which allow remote code execution (CVE-2017-0781 and CVE-2017-0782), one results in information leak (CVE-2017-0785) and the last allows an attacker to perform a Man-in-The-Middle attack (CVE-2017-0783).
Examples of impacted devices:
- Google Pixel
- Samsung Galaxy
- Samsung Galaxy Tab
- LG Watch Sport
- Pumpkin Car Audio System
