Terra 區塊鏈在 ASTRO、USDC、USDT 和 BTC 中價值 400 萬美元

週三，Terra 開發者因重入攻擊而暫時停止網路運營，導致超過 400 萬美元的各種代幣被盜

Terra blockchain was exploited for around $60 million in various tokens, including ASTRO, USDC, USDT, and BTC, on July 31.

7 月 31 日，Terra 區塊鏈被各種代幣利用，價值約 6,000 萬美元，其中包括 ASTRO、USDC、USDT 和 BTC。

According to blockchain security firm Beosin, the attacker exploited a reentrancy vulnerability in the timeout callback of ibc-hooks, a vulnerability that had been disclosed in April. This type of bug allows exploiters to trick a smart contract by making repeated calls to a protocol to steal assets, tricking the smart contract into authorizing the smart contract address to interact with a user’s wallet address.

據區塊鏈安全公司Beosin稱，攻擊者利用了ibc-hooks超時回調中的重入漏洞，該漏洞已於4月被披露。此類漏洞允許攻擊者透過重複調用協議來欺騙智能合約來竊取資產，欺騙智能合約授權智能合約地址與用戶的錢包地址進行交互。

Beosin reported that the Terra exploit led to the theft of $3.5 million in USDC stablecoin, $500,000 in USDT stablecoin, 2.7 bitcoins (BTC), and more than 60 million of Astroport’s ASTRO tokens.

Beosin 報告稱，Terra 漏洞導致價值 350 萬美元的 USDC 穩定幣、50 萬美元的 USDT 穩定幣、2.7 個比特幣 (BTC) 以及超過 6000 萬個 Astroport 的 ASTRO 代幣被盜。

Security firm Cyvers also reported on the incident, stating that 60 million ASTRO tokens were stolen in the exploit, which also affected other tokens, including 3.5 million USDC, 2.7 BTC, and 500,000 USDT.

安全公司 Cyvers 也報告了這起事件，稱 6,000 萬個 ASTRO 代幣在漏洞中被盜，這也影響了其他代幣，包括 350 萬個 USDC、2.7 個 BTC 和 50 萬個 USDT。

The Astroport team confirmed the incident, attributing it to an IBC vulnerability and adding that the exploit appeared to have been used to mint several tokens on the Terra chain, including ASTRO.

Astroport 團隊證實了這一事件，將其歸因於 IBC 漏洞，並補充說該漏洞似乎已被用來在 Terra 鏈上鑄造多個代幣，包括 ASTRO。

With the blockchain halted, no further tokens could be minted, limiting the extent of the damage.

隨著區塊鏈的停止，無法再鑄造更多的代幣，從而限制了損害的程度。

Terra blockchain announced the temporary halt of operations at block height 11430400 and informed users of the downtime via a post on X.

Terra 區塊鏈宣布暫時停止區塊高度 11430400 的操作，並透過 X 上的貼文通知用戶停機時間。

The network was paused to allow validators to upgrade their nodes and apply an emergency patch that fixed the vulnerability. The fix was completed by 04:19 UTC.

網路被暫停，以允許驗證者升級其節點並應用修復漏洞的緊急修補程式。修復已於 UTC 時間 04:19 完成。

Over 67% of the voting power on Terra supported this upgrade, ensuring the network’s stability and security.

Terra 超過 67% 的投票權支持此次升級，保證了網路的穩定性和安全性。

The network was set to resume operations at block height 114304050, with validators expected to quickly achieve the necessary quorum for the chain to restart.

網路原定在區塊高度 114304050 處恢復運行，驗證者預計將快速達到鏈重啟所需的法定人數。

Once operational, the network was expected to quickly process any pending transactions and return to normal functioning.

一旦投入運行，網路預計將快速處理任何待處理的交易並恢復正常運行。

In the aftermath of the Terra exploit, ASTRO, the native token of the Cosmos liquidity protocol Astroport, experienced a significant decline.

在 Terra 漏洞之後，Cosmos 流動性協議 Astroport 的原生代幣 ASTRO 經歷了大幅下跌。

CoinGecko data indicated that ASTRO fell by 56%. Meanwhile, Terra’s luna classic (LUNC) tokens saw a 3.4% decrease in the past 24 hours.

CoinGecko數據顯示ASTRO下跌了56%。與此同時，Terra 的 luna classic (LUNC) 代幣在過去 24 小時內下跌了 3.4%。

The exploit caused ASTRO’s price to drop sharply from $0.046 to a low of $0.013, although it later recovered to above $0.02 as efforts to address the vulnerability continued.

該漏洞導致 ASTRO 的價格從 0.046 美元大幅下跌至 0.013 美元的低點，儘管隨後隨著解決漏洞的努力的繼續，其價格恢復到 0.02 美元以上。
