Question
Richard, an attacker, aimed to hack loT devices connected to a target network. In this process. Richard recorded the frequency required to share information between connected devices. After obtaining the frequency, he captured the original data when commands were initiated by the connected devices. Once the original data were collected, he used free tools such as URH to segregate the command sequence. Subsequently, he started injecting the segregated command sequence on the same frequency into the loT network, which repeats the captured signals of the devices. What Is the type of attack performed by Richard In the above scenario?
Options
- ASide-channel attack
- BReplay attack
- CCrypTanalysis attack
- DReconnaissance attack

Explanation
WARNING - The stated correct answer C (Cryptanalysis attack) appears to be INCORRECT. The scenario explicitly and precisely describes a Replay Attack (option B): Richard (1) recorded the RF frequency used by IoT devices, (2) captured the original signals/commands transmitted between devices, (3) used URH (Universal Radio Hacker) to segregate the command sequences, and (4) re-transmitted ('replayed') those same captured signals on the same frequency to repeat the original device actions. This is the textbook definition of a replay attack - an adversary captures legitimate communications and retransmits them later to trigger the same action, without needing to understand or decrypt the data. Cryptanalysis involves mathematically breaking or analyzing cryptographic algorithms and ciphers, which is not mentioned anywhere in this scenario. The correct answer should be B (Replay attack). This appears to be an error in the provided answer key.
