Lido DAO has initiated an emergency vote to replace a compromised oracle following a cybersecurity incident linked to the Chorus One oracle system. The breach resulted in a loss of only 1.4 ETH, and Lido Finance has assured that the protocol remains secure and its stakers are unaffected. The incident highlights ongoing operational risks in decentralized finance (DeFi), including vulnerabilities related to off-chain components such as private keys and infrastructure. Security experts emphasize that social engineering tactics, including phishing and fake airdrops, continue to be major factors behind crypto hacks. While the compromised oracle raised concerns about the potential risk to Lido's $23 billion protocol, the actual financial impact was limited. This event underscores the persistent challenges in securing DeFi protocols against both technical and human-factor threats.
