Security researchers at Eurecom have identified fresh vulnerabilities in Bluetooth that open the door for hackers to engage in device impersonation and execute man-in-the-middle attacks. Named ‘BLUFFS,’ these six new exploits, uncovered by Daniele Antonioli, leverage two undisclosed vulnerabilities within the Bluetooth architecture, enabling the decryption of transmitted data. Notably, cybersecurity experts assert that these flaws transcend specific hardware or software configurations, impacting Bluetooth at a fundamental architectural level.

Massive Bluetooth Vulnerability Detected: All Devices Launched After 2014 Can Be Hacked & Exploited!

Universal Vulnerability: BLUFFS Exploits and Bluetooth Security Risks Across Devices

According to findings reported by Bleeping Computer, these vulnerabilities affect all devices equipped with Bluetooth 4.2, introduced in late 2014, as well as Bluetooth 5.4, unveiled earlier in the year. Apple’s AirDrop feature, reliant on Bluetooth for file transfers between devices, is also susceptible. This implies that a wide range of devices, including laptops, PCs, smartphones, and tablets, are vulnerable. The research paper outlines that virtually all Bluetooth-enabled devices are at risk of at least three out of the six BLUFFS attacks.

Addressing Bluetooth Vulnerabilities: User Challenges, Manufacturer Responsibilities, and Security Measures

Mitigating these Bluetooth vulnerabilities poses a challenge for users, as the exploits operate at an architectural level. Currently, users have limited options for addressing these issues, as the onus falls on device manufacturers to enhance security mechanisms and reject outdated, low-security authentication methods. The prospect of patches for existing devices remains uncertain.

For the time being, users can enhance their security by turning off Bluetooth when not in use, though this may be inconvenient for many. Additionally, exercising caution when sharing sensitive files or images via Bluetooth in public spaces can serve as a precautionary measure against potential exploitation of these newfound security flaws.
