Convergence 確認遭受 2.12 億美元駭客攻擊，懇求用戶撤回資產

去中心化金融協議 Convergence 已確認其於 8 月 1 日被智能合約漏洞攻擊，駭客鑄造並出售了 2.1 億美元

DeFi protocol Convergence has confirmed that it was hacked via a smart contract exploit on Aug. 1, with the attacker minting and selling $210 million in its native token, as well as stealing $2,000 in unclaimed staking rewards.

DeFi 協議 Convergence 已確認其於 8 月 1 日透過智慧合約漏洞被駭客攻擊，攻擊者鑄造並出售了 2.1 億美元的原生代幣，並竊取了 2,000 美元無人認領的質押獎勵。

According to a post-mortem from Wireshark, the pseudonymous founder of the Convergence protocol, the attacker exploited the protocol’s CvxRewardDistributor contract, allowing them to mint and sell 58 million CVG tokens for approximately $210,000.

根據 Convergence 協議的匿名創始人 Wireshark 的事後分析，攻擊者利用了該協議的 CvxRewardDistributor 合約，允許他們鑄造 5800 萬個 CVG 代幣，並以大約 21 萬美元的價格出售。

The attacker also stole approximately $2,000 of unclaimed rewards from Convex, a DeFi protocol designed to maximize rewards for Curve liquidity providers.

攻擊者還從 Convex 竊取了約 2,000 美元無人認領的獎勵，Convex 是一種 DeFi 協議，旨在最大限度地提高 Curve 流動性提供者的獎勵。

According to Etherscan, the attack occurred on Aug. 1 at around 3:00 am UTC.

據 Etherscan 稱，這次攻擊發生在 UTC 時間 8 月 1 日凌晨 3 點左右。

Blockchain security firm PeckShield noted that after minting the CVG tokens, the attacker quickly swapped it into 60 wrapped-Ether and 15,900 Curve.fi FRAX.

區塊鏈安全公司 PeckShield 指出，在鑄造 CVG 代幣後，攻擊者迅速將其兌換成 60 個包裝以太幣和 15,900 個 Curve.fi FRAX。

The movements have since led to a near-100% price wipeout of the CVG governance token, which is now trading at $0.0004 with a market cap of just $57,000, CoinMarketCap data shows.

CoinMarketCap 數據顯示，這些變動導致 CVG 治理代幣價格近 100% 下跌，目前該代幣的交易價格為 0.0004 美元，市值僅為 57,000 美元。

Convergence said the attack was possible because the team accidentally removed an essential line of code in its smart contract, which distributes CVG staking rewards. They made the change after the smart contract code was audited four times.

Convergence 表示，這次攻擊之所以可能發生，是因為該團隊意外刪除了智慧合約中的一行重要代碼，該代碼用於分配 CVG 質押獎勵。他們在智能合約程式碼經過四次審核後做出了更改。

“The modification (gas-optimization on the first hand) led us to remove the line of code that was checking the input given to the function,” it explained.

「修改（首先是氣體優化）導致我們刪除了檢查函數輸入的程式碼行，」它解釋道。

The attacker used this to exploit the CvxRewardDistributor contract through the claimMultipleStaking function.

攻擊者利用漏洞透過 ClaimMultipleStake 函數來利用 CvxRewardDistributor 合約。

This meant the staking contract couldn’t be validated, allowing the attacker to pass a separate malicious contract with the same signature as the claimCvgCvxMultiple function.

這意味著質押合約無法驗證，從而允許攻擊者傳遞與 ClaimCvgCvxMultiple 函數具有相同簽名的單獨惡意合約。

The attacker then minted all tokens dedicated to staking emissions and then dumped them into CVG liquidity pools, Convergence said.

Convergence 表示，攻擊者隨後鑄造了所有專門用於質押排放的代幣，然後將它們轉儲到 CVG 流動性池中。

Convergence says that user funds are safe, but has recommended users withdraw assets from the platform.

Convergence表示用戶資金是安全的，但建議用戶從平台提取資產。

“Due to the exploit, the rewards contract for the Stake DAO integration is currently broken. It will be fixed, and stakers will be able to claim their rewards once it’s done. No rewards are lost for Stake DAO integration users," it said.

「由於該漏洞，Stake DAO 整合的獎勵合約目前已被破壞。該問題將被修復，一旦完成，質押者將能夠獲得獎勵。 Stake DAO 整合用戶不會損失任何獎勵。

Convergence works to aggregate liquidity, boost returns and enable liquid locking across the Curve Finance ecosystem.

Convergence 致力於聚合流動性、提高回報並實現整個 Curve Finance 生態系統的流動性鎖定。

The total value locked on Convergence fell from $5.79 million to $3.69 million, DefiLlama data shows.

DefiLlama 數據顯示，Convergence 鎖定的總價值從 579 萬美元降至 369 萬美元。

The cryptocurrency ecosystem lost around $266 million to hacks in July, mostly coming from the $230 million hack of Indian trading platform WazirX on July 18.

7 月份，加密貨幣生態系統因駭客攻擊損失了約 2.66 億美元，其中大部分來自 7 月 18 日印度交易平台 WazirX 遭受的 2.3 億美元駭客攻擊。
