MetaMask Hack? Ethereum Validators Exit After Security Incident

MetaMask has started exiting affected Ethereum validators following an infrastructure security incident involving its non-custodial staking operations with Lido.

All affected validators are expected to exit by October 7, while the full withdrawal process could take up to ~45 days.
Lido says $stETH holders need no action, while Aave reports no market impact so far.

The exact attack vector remains under investigation.
