CEH pg 2589 - Answer Replay Attack Types of SDR-based attacks performed by attackers to break into an IoT environment:  Replay Attack This is the major attack described in IoT threats, in which attackers can capture the command sequence from connected devices and use it for later retransmission. An attacker can perform the below steps to launch a replay attack: o Attacker targets the specified frequency that is required to share information between devices o After obtaining the frequency, the attacker can capture the original data when the commands are initiated by the connected devices o Once the original data is collected, the attacker uses free tools such as URH (Universal Radio Hacker) to segregate the command sequence o Attacker then injects the segregated command sequence on the same frequency into the IoT network, which replays the commands or captured signals of the devices

The correct option is D. Replay

Software-defined radio (SDR)-Based Attacks on IoT The attacker uses software defined radio (SDR) to examine the communication signals in the IoT network and sends spam content or texts to the interconnected devices. Replay Attack - The attacker obtains the specific frequency used for sharing information between connected devices and captures the original data when a command is initiated by these devices. The attacker segregates the command sequence and injects it into the IoT network. (P.2605/2589)
