Mango Markets エクスプロイターが Aave の抜け穴を悪用しようとした: 試みが失敗した方法は次のとおりです。

Mango Market's exploiter Avraham Eisenberg's attempt to replicate his “highly profitable trading strategy” on decentralised finance (DeFi) protocol Aave has failed, resulting in the loss of millions. As per on-chain analytics firm Lookonchain, an address associated with Eisenberg, transferred $40 million (roughly Rs. 325 crore) worth USD Coin (USDC) into Aave to borrow Curve (CRV) token with the intention of shorting. This resulted in CRV price tanking by roughly 26 percent to $0.464 (roughly Rs. 37.34) from $0.625 (roughly Rs. 51.14) over the past week.

That said, the move didn't go entirely as planned as the community rallied behind CRV, buying the DeFi token and causing its value to spike 46 percent in the last 24 hours to as high as $0.71 (roughly Rs. 57.63).

Blockchain analytics firm Arkham Intelligence tweeted Eisenberg might be baiting people to believe that he was shorting CRV to cause the liquidation of Michael Egorov, founder of the DeFi network.

According to Arkham Intelligence, Eisenberg's real target was AAVE's vulnerable looping system and his borrowings could leave the DeFi network with severe bad debt. The blockchain analytics firm added, “To liquidate Avi's position, AAVE liquidators will have no way to buy back all the CRV he borrowed. On-chain, there is no liquidity to pay back more than ~20 percent of the position. AAVE will have to sell significant amounts of tokens from the safety module to cover this loss.”

10月には、 Eisenberg explained Aave の貸出ポリシーを操作して、大量に借り入れて投棄し、Aave に不良債権を残すことが可能であったこと。

Following the failure of the short strategy, Aave said the liquidation process of its CRV pool was successful and went as planned. But it noted that the position was not fully covered as 2.6 million CRV ($1.6 million or roughly Rs. 13 crore) remained, representing less than 0.1 percent of the positions on the protocol.

新しい ガバナンス提案 is now live on Aave that will prevent another price manipulation on the platform.

一方、Aave コミュニティは、開発者が以前にその可能性についていくつかの警告を受けていたため、このシナリオを防ぐために何かをした可能性があると指摘しました。
