Which type of attacks is a concern with Bluetooth during the pairing process?

During the Bluetooth pairing process, sniffing is a significant concern because it involves intercepting and capturing the wireless communication between devices. When two devices pair, they exchange authentication keys and other sensitive information that can be vulnerable to interception if the pairing is not adequately secured. Attackers can use sniffing techniques to eavesdrop on this communication, potentially gaining access to the pairing keys and compromising the security of the Bluetooth connection.

This risk is particularly pertinent in Bluetooth devices because the wireless nature of the communication allows for greater exposure to nearby adversaries. Without proper security measures, such as encryption or authentication, the data exchanged during pairing can be susceptible to unauthorized access, leading to a variety of security issues.

Other attack types like cross-site scripting and SQL injection are primarily associated with web applications and databases, respectively, rather than wireless communication protocols like Bluetooth. While brute force attacks can target any system with passwords or encryption keys, they are less relevant during the initial pairing phase where the concern focuses mainly on intercepting communications rather than attempting to guess or force access into a system. Thus, sniffing stands out as the most pertinent threat during the Bluetooth pairing process.
