Nomad

Nomad, a cryptocurrency bridge that lets users swap tokens between blockchains, was targeted in a frenzied attack which left almost $200 million of its funds drained.

Nomad notified law enforcement and was working around the clock to address the situation.

The exploit was made possible by a misconfiguration of the project’s main smart contract that allowed anyone with a basic understanding of the code to authorize withdrawals for themselves.

The hack was so chaotic, all you had to do was to find a transaction that worked, find/replace the other person’s address with yours, and then re-broadcast it.
