Terra 区块链因针对 Astroport (ASTRO) 的攻击而损失超过 600 万美元

据区块链安全公司 Beosin 报道，基于 Cosmos 的 Terra 区块链今天遭遇漏洞攻击，损失超过 600 万美元。

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).

据区块链安全公司 Beosin 称，由 Cosmos 提供支持的 Terra 区块链今天遇到了漏洞，导致了超过 600 万美元的巨额损失。该漏洞涉及盗窃 6000 万个 ASTRO 代币、价值 50 万美元的 Tether USD (USDT)、价值 350 万美元的美元代币 (USDC) 和 2.7 个比特币 (BTC)。

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

为了响应该漏洞，Terra 区块链在区块高度 11430400 处停止了近 20 分钟。

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，攻击者利用了与 Cosmos 生态系统的区块链间通信（IBC）功能相关的重入漏洞，该漏洞此前于今年 4 月被披露。

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.

为了缓解这个问题，Terra 实施了紧急升级，在 Terra 生态系统中总共拥有超过 67% 投票权的验证者已经升级了其节点，以防止漏洞再次发生。

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.

该漏洞的消息传出后，去中心化交易所 Astroport 原生的 ASTRO 代币价格大幅下跌，跌幅高达 71%。相比之下，LUNA 代币的价格保持相对稳定，在过去 24 小时内下跌了 3%。

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

此外，Terra 上的总锁定价值（TVL）在漏洞利用后也受到了打击，下降了 15%。
