Spoofing and Replay Attacks

Spoofing and replay attacks are malicious techniques used to deceive authentication systems by mimicking legitimate credentials or reusing valid data packets. In the context of financial derivatives and trading platforms, a replay attack occurs when an attacker captures a valid transaction or login request and transmits it again to trick the system into repeating the action.

Spoofing involves creating a fake identity or biometric input to bypass security checks. These attacks exploit the underlying logic of the communication protocols between the user and the server.

Defense mechanisms include the use of nonces, timestamps, and encrypted sessions to ensure that each request is unique and can only be processed once.
