BurpSuite Replay Attack 2.2. 1 Replay Attack Replay Attacks, also known as Replay Attacks, Replay Attacks or FreshnessAttacks, refers to the attacker sending a packet received by the destination host to deceive the system, which is mainly used in the identity authentication process and destroys the correctness of authentication. It is a type of attack that repeats an effective data transmission maliciously or fraudulently. The replay attack can be carried out by the initiator or by the enemy that intercepts and retransmits the data. Attackers use network monitoring or other means to steal authentication credentials and then re-send them to the authentication server. From this explanation, encryption can effectively prevent session hijacking, but it cannot prevent replay attacks. Replay attacks can occur during any network communication. Replay attack is one of the common attacks used by hackers in the computer world. Its written definition is abstract to people who do not know cryptography. However, through learning, we know that the best way to defend against replay attacks is timestamp. Simply speaking, what is timestamp, that is, the verification code that we need to enter when visiting some websites to log in, and replay attacks cannot cope with every time we log in.
