Lido 節點漏洞揭露與初步應對

開源庫 Tailon 中的隱患與解決方案

dWallet Labs 在 2023 年 7 月向 InfStones 警告開源代碼庫 Tailon 的漏洞,此漏洞已被迅速解決,也因此實施了一連串預防性的安全措施。

Lido Finance 是作為以太坊上最大的流動權益質押協議,管理價值超過 190 億美元的 ETH。用戶透過存入 ETH,參與由運營商網路管理的驗證節點中,獲得相應的衍生代幣。

Lido Finance 澄清:SAFU

積極確保用戶資產安全

Lido Finance 證實,該漏洞可能與根級訪問權限相關,影響了 InfStones 的 25 個驗證節點伺服器。儘管如此,Lido 強調,目前沒有密鑰泄露或濫用的跡象。為了進一步保障用戶資產的安全,dWallet Labs 建議對所有可能受漏洞影響的節點進行驗證密鑰輪換。

To clarify: There is currently no indication of key leakage or compromise, and the vulnerability may not affect validators related the Lido protocol.

InfStones 的回應與後續行動

InfStones 已確保網路完整性

InfStones 指出受影響的系統僅占其整體基礎設施的一小部分,不足 0.1%。該公司已同意主動退出其驗證節點,並過渡到新的密鑰,待Lido Finance 的治理批准。此舉旨在確保以太坊網路的持續穩定運作,並保障用戶資產的安全。
