Kelp DAO被盜資金洗錢

鏈上分析師 Specter 監測顯示,北韓駭客組織 TraderTraitor 於 4 月 22 日開始對 KelpDAO 被盜資金實施洗錢操作,距 Arbitrum 安全委員會凍結約 30,766 枚 ETH 後僅三小時。攻擊者將資金以 THORChain 橋接至比特幣網路,導致日交易超過 30 日日均值 10 倍。

洗錢操作細節:三個錢包、混合手法與跨鏈轉移

攻擊者將剩餘資金拆分至三個錢包:第一個持有約 2.5 萬枚 ETH(約 5,760 萬美元),第二個持有約 2.57 萬枚 ETH(約 5,920 萬美元),第三個在收到資金後立即開始洗錢,目前僅剩約 3,800 枚 ETH(約 800 萬美元)。

被盜資金在洗錢過程中與 BTC Turk(2025)及 Bybit(2025)駭客事件的非法所得相混合,這是 TraderTraitor 組織的典型操作模式——通過整合多起事件的資金,增加鏈上追蹤難度。Specter 指出,雖然其追蹤到 356 個相關地址,但仍有若干中間錢包未納入統計,整個過程使用的地址總數超過 400 個。

KelpDAO 攻擊的連鎖影響:Aave 壞帳到 DeFi TVL 驟降

根據 Messari 分析,此次攻擊的根本原因在於 LayerZero EndpointV2 的 1:1 DVN 配置,允許攻擊者偽造跨鏈訊息。攻擊者入侵兩個 LayerZero DVN 節點後,模擬 rsETH 銷毀並觸發了 116,500 個 rsETH 的未授權釋放。

下游影響迅速蔓延至整個 DeFi 生態:Aave 壞帳估計在 1.237 億至 2.301 億美元之間,TVL 從約 458 億美元降至 357 億美元;整體 DeFi TVL 在 48 小時內下降超過 130 億美元;AAVE 代幣下跌約 25%;WETH 市場達到 100% 的使用率,引發 62 億美元的資金外流。

早期應對措施與 rsETH 持有者補償計畫

主要應對措施包括:Arbitrum 安全委員會凍結約 30,766 枚 ETH;Kelp 暫停主網和 L2 層所有 rsETH 合約;LayerZero 禁止未來使用 1:1 DVN 配置。Kelp 正考慮對 rsETH 持有者採取 16% 的比例損失補償措施,但 Messari 指出此舉可能影響受影響協議的用戶信心和恢復動態。

常見問題

TraderTraitor 為何選擇 THORChain 作為洗錢通道?

THORChain 是無需許可的跨鏈流動性協議,允許在不同區塊鏈之間兌換資產且不要求 KYC 驗證。此前在 Bybit 駭客事件中,TraderTraitor 也採用了相同的 THORChain 通道,顯示這已成為北韓駭客組織在大規模竊盜後的固定操作模式。

此次洗錢為何要與 Bybit 和 BTC Turk 事件的資金混合?

資金混合是洗錢的標準操作手法,將多起事件的被盜資金合併後,使追蹤人員更難以識別特定資金的原始來源和歸屬。KelpDAO 被盜資金在 THORChain 流通過程中,已與 2025 年 BTC Turk 及 Bybit 駭客事件的非法資金相混合,形成更難解開的資金鏈。

Kelp 的 16% 比例損失補償計畫如何影響 rsETH 持有者?

若補償計畫最終確認,rsETH 持有者將按持倉比例承擔約 16% 的損失,意即每 100 個 rsETH 的持有者,資產名義價值將被打折約 16%。補償機制有助於部分緩解受影響用戶的損失,但也可能影響市場對 rsETH 及 Kelp 協議整體的信心恢復速度。
