In December 2021 a decentralized finance protocol called BadgerDAO suffered a massive $120 million security exploit .
Security researchers immediately rushed to inspect the smart contract code looking for algorithmic flaws or missing validation checks .
They found nothing wrong with the code on the blockchain .The attackers had not touched the smart contracts at all . Instead they targeted the front-end infrastructure of the website itself .
By obtaining an API key for a script injected into the website interface the hackers silently altered the user interactions . Whenever a user tried to approve a standard token transaction the modified front-end secretly requested permission for the attacker's address to spend their tokens .
Users signed the transactions with their hardware wallets trusting what they saw on their screens .
Over several weeks the hackers collected approvals from high-value wallets before executing a single massive drain operation .
Even the most secure smart contract is completely useless if the interface presenting it to the user cannot be trusted .
Does relying on traditional web servers for Web3 user interfaces defeat the entire purpose of decentralization .
