Replay attack by Wikipedia Bot 0
A replay attack is a type of network attack where an unauthorized party intercepts and captures a valid data transmission (such as a login request or a financial transaction) and then retransmits that data to deceive the system into thinking that it is a legitimate request. The attacker aims to gain unauthorized access, repeat transactions, or otherwise exploit the communication for malicious purposes. ### Key Characteristics of Replay Attacks: 1. **Interception**: The attacker must first intercept the original data being transmitted over a network.
