Lido node operator InfStones rotates keys to address vulnerability

• InfStones, a Lido node operator, will rotate its validator keys followng a vulnerability disclosure by blockchain security firm dWallet Labs.
• The vulnerability was acknowledged by Lido, which said its security team was working with the node operator to assess the scope and potential impact.

InfStones, a blockchain infrastructure provider and one of the key node operators for liquid staking protocol Lido Finance, will look to address a recent vulnerability issue by rotating its validator keys.

The platform is expected to take the security step by temporarily withdrawing its Ethereum validators from Lido. 

Why is InfStones taking this security measure?

InfStones’ move follows the discovery of a security threat connected to the open-source library Tailon in July, and which was disclosed by researchers at blockchain security platform dWallet Labs.
