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?

• A.CrypTanalysis attack
• B.Side-channel attack
• C.Replay attack
• D.Reconnaissance attack
  Cryptanalysis is that the science of cracking codes and secret writing secrets. it's accustomed violate authentication schemes, to interrupt scientific discipline protocols, and, additional benignantly, to seek out and proper weaknesses in coding algorithms.
  It may be employed in IW applications - for instance, shaping Associate in Nursing encrypted signal to be accepted as authentic. Competitors UN agency are ready to discover the key can currently need to use it to their advantage, thus they're going to need to send phony encrypted messages to the supply so as to gain data or gain a bonus. It might even be used to pretend to be the supply so as to send phony data to others, UN agency currently can assume that it came from the official supply.
  Among the kinds of attacks are:
  Ciphertext solely attacks
  best-known plaintext attacks
  Chosen plaintext attacks
  Chosen ciphertext attacks
  Man-in-the-middle attacks
  aspect channel attacks
  Brute force attacks
  Birthday attacks
  There are variety of different technical and non-technical cryptography attacks to that systems will fall victim. cryptographical attacks may be mounted not solely against coding algorithms, however conjointly against digital signature algorithms, MACing algorithms and pseudo-random variety generators.
  Ciphertext solely Attack
  A ciphertext solely attack (COA) could be a case within which solely the encrypted message is accessible for attack, however as a result of the language is thought a frequency analysis may be tried. during this state of affairs the aggressor doesn't apprehend something concerning the contents of the message, and should work from ciphertext solely.
