MetaMask reported a security incident on September 28, 2026, involving unauthorized access to part of its infrastructure. The incident led to the diversion of approximately 0.385 ETH in execution-layer staking rewards, but no customer funds or wallet infrastructure were compromised. MetaMask exited affected Ethereum validators as a precautionary measure, ensuring that users' Secret Recovery Phrases and private keys remained secure. The company has been working with external security specialists to contain the incident and has assured users that their staked principal is safe. Affected customers are being contacted for refunds of the diverted rewards, and no action is required from MetaMask wallet users. The incident highlights the importance of self-custody in non-custodial wallets.
