In this video, I'll be showcasing our first grand milestone, which is a hack replication of the notorious Not My Bridge hack. I'll explain how this hack could have been prevented by integrating a circuit breaker. The hack was made possible through a faulty update of the replica contract, which allowed anyone to forge messages and gain unauthorized access to tokens. By integrating a circuit breaker into the code, we can track token outflow and set a limit to prevent such attacks. I'll demonstrate the hack on the Nomad bridge with a circuit breaker and show you how it effectively protects against unlawful outflows and exploits.
