Distributed Denial of Service (DDoS) attacks are particularly effective against IoT devices due to their limited computational resources. IoT devices are also commonly used as part of botnets to conduct large-scale DDoS attacks because they are usually always on and connected to the internet. Incorrect answers, such as Bluejacking and Bluesnarfing, are Bluetooth-related attacks that target mobile devices specifically and not IoT devices in general. SQL injection is a web application attack and does not directly relate to the exploitation of IoT devices.
