Abracadabra Money 确认 $6.49M 漏洞利用;计划通过回购、销毁流程获得报酬

Algoine News
Summary:
跨链借贷平台 Abracadabra Money 证实了涉及其基于以太坊的借贷系统的 649 万美元漏洞,导致其 Magic Internet Money (MIM) 稳定币暂时贬值。该平台的工程师正在调查该漏洞,该漏洞被区块链安全公司PeckShield和CertiK标记,并计划通过回购和销毁过程来补偿受害者。
Abracadabra Money 是一个跨多个区块链网络运营的借贷平台,已确认存在安全漏洞,导致 649 万美元的损失。这是由于该协议基于以太坊的大锅存在问题,该大锅有助于借入 Magic Internet Money (MIM) 稳定币来抵押各种抵押资产。MIM开发人员认识到了该漏洞,并保证正在进行调查。他们进一步补充说,那些受违规行为影响的人将通过回购和销毁的过程获得补偿。 区块链安全公司 PeckShield 周二发现了 649 万美元的妥协。据报道,匿名攻击者使用单个以太币发起了攻击,该以太币通过加密货币混合器Tornado Cash汇集。在漏洞披露后不到 60 分钟,与美元挂钩的算法稳定币 MIM 跌至 0.77 美元,失去了美元链接。然而,根据 CoinMarketCap 的数据,它反弹到目前的 0.94 美元。 另一家区块链安全公司CertiK表示,利用性攻击可能是由于“四舍五入问题”而产生的。他们详细阐述了攻击者如何习惯性地调用“userBorrowPart()”函数,然后通过协议的 v4 大锅调用“repay()”。这表明攻击者不断借款和偿还贷款,这一行为导致合同资金流失。 Abracadabra 的 Magic Internet Money 此前曾在 2022 年偏离其挂钩,这是 Terra Luna 生态系统崩溃的后果。因此,在 8 月份,该协议将代币的利率提高了 200%,旨在管理与 Curve 协议相关的风险。
