Ethena Labs, a synthetic dollar protocol on Ethereum, experienced a frontend hack after its domain registrar account was compromised. The hack led to phishing transactions aimed at stealing user tokens. Users have been warned to avoid Ethena's interface, refrain from signing transactions, and disconnect their wallets immediately to stay safe. Ethena Labs has temporarily shut down its frontend website while working closely with affected partners to address the issue. Despite the breach, the protocol itself remains unaffected and user funds are safe.
