Your wireless network has been breached and it seems as though the attacker has modified a portion of your data that is used with a stream cipher. this was used to expose wirelessly-encrypted data. what type of attack is this?

IV attack

Explanation:

 IV attack is stand for the initialization vector attack that are used over the wireless network an it is used as the encrypted packet during the process of transmission. An initialization vector attack basically attempts for exploits for exposing the encrypted information.

 According to the question, the IV attack is basically used with the stream cipher for exposing the information wirelessly.

The initialization vector is one of the arbitrary number that are used in the for  of secret key in the system and it helps in prevent the duplicate character in ciperhtext.

 Therefore, IV attack is the correct answer.

i think so.
