What is BlueBorne?

BlueBorne: The Silent Cyberthreat Using Bluetooth to Conquer Devices and Networks

BlueBorne is a cybersecurity threat related to Bluetooth technology. It is defined as a form of malware that exploits vulnerabilities in Bluetooth technology used in devices such as computers, mobile phones, and other Internet of Things (IoT) devices. This form of cyber-attack is particularly deceptive, as it does not require any action from the targeted device's owner. As soon as Bluetooth is enabled on a device, it becomes susceptible to a BlueBorne attack.

BlueBorne was first uncovered by an IoT security company, Armis Labs, in September 2017. Analysis revealed that this threat could potentially affect billions of devices worldwide. The name "BlueBorne" was coined by its discoverers as a conflation of "Bluetooth" and "Airborne," indicating the method of transmission.

BlueBorne exploits a variety of vulnerabilities present in the implementation of the Bluetooth protocol in various operating systems, including Android, iOS, Windows, and Linux. It bypasses the conventional need for pairing devices acknowledging a data exchange request. Instead, it quietly invades the device, takes control, and starts executing malicious activity.

The BlueBorne attack has two stages. Firstly, the attacker identifies susceptible Bluetooth-enabled devices within approximately 30 feet. The range could be extended if the attacker employs a Bluetooth amplifier. Following the preliminary identification, the second phase involves the attacker covertly linking their device with the victim's device and exploiting the discovered susceptibilities to start the attack.

One of the distinct characteristics of BlueBorne is its potential for viral spread. For instance, a compromised device can automatically emit malicious packets to any nearby Bluetooth-enabled device, potentially leading to an extraordinary rate of infection.

BlueBorne's pervasiveness is alarming because many people leave Bluetooth turned on all the time, not recognizing this innocuous act puts them at risk. Traditional antivirus software were of relatively little help against this threat since BlueBorne attacks operated at the device level, avoiding the application or data layers were most antivirus software focus.

The aftermath of a successful BlueBorne attack can vary greatly. An attacker might simply choose to control the device remotely, perhaps to use it as a bot in a larger network. They could also opt to extract personal information and sensitive data from the device. Businesses could face significant consequences if cybercriminals gain access to confidential company data through a vulnerable device.

Thankfully, device manufacturers took swift action to patch the vulnerabilities exposed by the BlueBorne threat. due to the fragmented nature of the IoT security landscape, closing these vulnerabilities proved to be challenging.

BlueBorne is a sophisticated malware that reminds us of the complexities and dangers of the interconnected world we live in. As IoT devices become increasingly intertwined in our daily lives, there will always be a challenge to maintain a high standard of security. Awareness about potential threats like BlueBorne can help users better protect themselves and act with caution when using Bluetooth devices. It also emphasizes the need for continued diligence from device manufacturers and technology companies to prioritize security and address vulnerabilities promptly.
