Nowadays, most of us look down on Bluetooth as a vestigial feature that we only turn to if we have no alternative for sharing media. On the contrary, this devil-may-care attitude has elevated the status of Bluetooth to something so commonplace to the modern technology user.
Unfortunately, a few individuals realize the security risks associated with Bluetooth-enabled devices. Even more alarming is that as the cybercrimes associated with Bluetooth grow increasingly complex, they often lead to unprecedented impacts on an organization’s cybersecurity infrastructure since most CISOs and CSOs ignore the warning signs.
Before we can analyze the ways the evolving nature of Bluetooth hacks has impacted cybersecurity, we’d like to bring our readers up to mark some of the threats facing Bluetooth threats.
What are some of the threats facing Bluetooth devices?
Usually, the cybersecurity industry tends to overlook vulnerabilities and threats almost immediately after they are brought to the general public’s notice or if they influence a lesser talked-about technological phenomenon.
Bluetooth-enabled devices’ most prominent threats include bluejacking and blue bugging. Bluejacking exploits a fundamental Bluetooth feature that allows users to send messages to connected devices within range.
Although the name bluejacking implies that the hacker hijacks into the victims’ device, the reality is quite different since the bluejacker only has enough power to send messages and interrupts the communication between two connected devices.
Using Bluetooth as an entry point, the hacker uses bluejacking to intercept communication and send messages. Fortunately, however, the consequences of bluejacking can easily be prevented by configuring the device’s settings to an invisible or non-discoverable mode.
Similarly, bluebugging is a hacking method that allows hackers to access mobile commands on a sabotaged Bluetooth-enabled device. As the name suggests, blue bugging will enable hackers to bug or eavesdrop on their victim’s mobile devices. Hackers may exploit the bugged Bluetooth device.
They usually employ blue bugging to remotely control and intercept communication on mobile devices. However, cybercriminals may also use blue bugging to send and read text messages and surveil phone calls being sent to and from the mobile phone.
Although bluejacking and blue bugging are dangerous enough to cause substantial damage to a Bluetooth-enabled device, modern Bluetooth threats such as BlueBorne are far more damage-inducing than both hacking tactics combined.
First brought to the public’s attention around the end of 2017, the BlueBorne vulnerability was thought to be resolved in the multiple devices it affected. On the contrary, however, newly surfaced research points towards a rather bleak reality: several devices affected by the vulnerability failed to receive sufficient security fixes.
Instead of operating as a conventional Bluetooth vulnerability, the BlueBorne threat targeted different parts of a Bluetooth-enabled device and would pretend to be a device that wished to connect to another device. Still, BlueBorne would exploit that connection and require the user to perform a specific action.
In retrospect, the BlueBorne threat brought into notice the growing sophistication levels of the Bluetooth hacks facing individuals and enterprises today, along with bringing into light that regardless of the lessons learned from the BlueBorne vulnerability, there are still several unsuspecting devices that remain vulnerable to similar threat vectors.
What do the modern-day Bluetooth threats imply for the future of cybersecurity?
Although the discussed threats are severe enough to scare even the least invested person in cybersecurity, the question remains, “Why should anyone care?”
Well, the answer is simple. Bluetooth hacks matter because we are all impacted by them in one way or another. Because there are over 8.2 billion Bluetooth-enabled devices globally, the scope of damage that can be caused becomes quite evident.
Not only are the threats we’ve mentioned above of interest to organizations invested in cybersecurity, but they also matter to the cybersecurity landscape since they point toward a changing and ever-evolving threat landscape.
Propagators of these threat vectors understand the value of data and leverage the security loopholes present within Bluetooth’s technologies to gain more access to the confidential information of a whopping 8 billion users!
Considering the devastating aftermath of a data breach, particularly in the blue bugging where a hacker can access everything inside a victim’s phone, the need for better cybersecurity becomes quite evident. Let’s consider an example where an individual trades in foreign exchange to demonstrate further.
Considering how sneaky Bluetooth hacks tend to be, an individual could have their entire analytics in the hands of hackers without even knowing it. This is entirely related to poor risk management, one of traders’ biggest mistakes.
