Terra 區塊鏈因針對 Astroport (ASTRO) 的攻擊而損失超過 600 萬美元

根據區塊鏈安全公司 Beosin 通報，基於 Cosmos 的 Terra 區塊鏈今天遭遇漏洞攻擊，損失超過 600 萬美元。

The Terra blockchain, powered by Cosmos, encountered an exploit today, leading to a substantial loss of over $6 million, according to blockchain security firm Beosin. The exploit involved the theft of 60 million ASTRO tokens, $500,000 in Tether USD (USDT), $3,5 million in USD Coin (USDC), and 2,7 Bitcoins (BTC).

據區塊鏈安全公司 Beosin 稱，由 Cosmos 提供支援的 Terra 區塊鏈今天遇到了漏洞，導致了超過 600 萬美元的巨額損失。該漏洞涉及竊取 6,000 萬個 ASTRO 代幣、價​​值 50 萬美元的 Tether USD (USDT)、價值 350 萬美元的美元代幣 (USDC) 和 2.7 個比特幣 (BTC)。

In response to the exploit, the Terra blockchain was halted at block height 11430400 for nearly 20 minutes.

為了回應該漏洞，Terra 區塊鏈在區塊高度 11430400 處停止了近 20 分鐘。

Beosin's analysis suggests that the attacker exploited a reentrancy vulnerability related to the Inter-Blockchain Communication (IBC) function of the Cosmos ecosystem, which was previously disclosed in April this year.

Beosin 的分析表明，攻擊者利用了與 Cosmos 生態系統的區塊鏈間通訊（IBC）功能相關的重入漏洞，該漏洞先前於今年 4 月被揭露。

To mitigate the issue, Terra has implemented an emergency upgrade, and validators collectively holding over 67% of the voting power on Terra's ecosystem have upgraded their nodes to prevent the exploit from recurring.

為了緩解這個問題，Terra 實施了緊急升級，在 Terra 生態系統中總共擁有超過 67% 投票權的驗證者已經升級了其節點，以防止漏洞再次發生。

Following the news of the exploit, the price of ASTRO tokens, which are native to the decentralized exchange Astroport, experienced a significant drop of up to 71%. In contrast, the price of LUNA tokens remained relatively stable, showing a decline of 3% over the last 24 hours.

該漏洞的消息傳出後，去中心化交易所 Astroport 原生的 ASTRO 代幣價格大幅下跌，跌幅高達 71%。相比之下，LUNA 代幣的價格保持相對穩定，在過去 24 小時內下跌了 3%。

Moreover, the total value locked (TVL) on Terra also took a hit after the exploit, decreasing by 15%.

此外，Terra 上的總鎖定價值（TVL）在漏洞利用後也受到了打擊，下降了 15%。
