ChainCatcher message, Alchemix tweeted that the AIP 96 proposal has been executed for the affected alETH Bridger in the Curve pool attack incident, and all parties have been compensated.In addition, the AIP 95a proposal regarding "restoring support for alUSD on Optimism/Arbitrum chains" has been fully executed except for the final step, which includes depositing POL into RAMSES. alUSD is now fully supported on L2.

ChainCatcher message, on-chain data shows that the Curve pool attacker has returned a total of 4,820 alETH and 2,258 ETH to the Alchemix Finance protocol, approximately 12.7 million dollars.The Curve Finance attacker explained their motivation for the refund: "I saw some ridiculous opinions, so I want to clarify that I am returning this to you not because you can find me, but because I don't want to ruin your project. For many people, this might be a lot of money, but for me, it's nothing. I am smarter than all of you."

ChainCatcher message, the alETH attacker has returned 3,819.55 alETH to Alchemix Finance: Dev, worth approximately 6.67 million USD. Previously, the attacker had returned 1,000 alETH to Alchemix Finance: Dev.

ChainCatcher message, the hacker marked as "Alchemix/CurveFinance Exploiter" has returned 1000 alETH to Alchemix Finance: Dev.

ChainCatcher message, the alETH attacker left a message to the Curve deployment address via an on-chain transfer: "Please confirm that the address 0xbabe... is the only address for Curve, to ensure we don't get it wrong." Curve replied: "Please return the funds to the Alchemix multi-signature address."

ChainCatcher message, Curve Finance stated that due to issues with the Vyper compiler in versions 0.2.15-0.3.0, the following pools were hacked: crv/eth, aleth/eth, mseth/eth, peth/eth.Another potentially affected mining pool is Arbitrum's tricrypto. Auditors and Vyper developers could not find any profitable vulnerabilities, but please also withdraw from using it.

ChainCatcher news, DeFi lending protocol Alchemix tweeted that Curve Finance notified Alchemix that their alETH/ETH pool could be attacked due to a vulnerability in Vyper. Alchemix quickly removed the AMO-controlled liquidity from the Curve pool through the AMO contract. The vulnerability was executed on the Curve pool contract. Alchemix's smart contracts were not attacked, and the funds are safe.The process requires three transactions: withdrawing LP tokens from Convex, extracting alETH from the Curve pool, and withdrawing ETH from the Curve pool. The first transaction to unstake LP tokens from Convex has been executed, and after the second transaction, 8000 ETH was removed from the Curve pool. There is still about 5000 ETH of liquidity controlled by AMO in the Curve pool. During the process of removing the remaining liquidity, the alETH/ETH Curve pool was attacked by an attacker. Currently, the alETH reserves have lost approximately 5000 ETH.For users, the funds in the Alchemix treasury are safe, and all Alchemix contracts are unaffected. Providing liquidity in the alETH/ETH Curve pool is unsafe. Providing liquidity for alETH elsewhere is technically safe, but attackers may exploit this liquidity to sell alETH for ETH. The fair price of alETH is currently unknown, and any users holding alETH or LP alETH face this uncertainty. Alchemix advises any LPs providing liquidity in the alETH pool on the decentralized exchange Saddle Finance and the frxETH pool on Curve to withdraw their liquidity as soon as possible.

ChainCatcher message, Curve Finance stated on Twitter that some stable pools (alETH/msETH/pETH) using Vyper 0.2.14 have been attacked due to a reentrancy lock failure. Currently, Curve is assessing the situation, and other pools are safe. Additionally, Curve further stated, "The dangerous combination is the affected Vyper version with the use of pure ETH."
