Lido, Ethereum’s largest liquid staking protocol, avoided a major security incident after one of its nine oracle keys was compromised in what appears to be a low-impact but serious breach involving validator operator Chorus One.Lido secures over 25% of all ETH staked on Ethereum, making it one of the most systemically important protocols in the Ethereum ecosystem.The compromised key was tied to a hot wallet used for oracle reporting, leading to the theft of just 1.46 ETH ($4,200) in gas fees
