北京时间4/19日上午,dForce基金会支持的主要DeFi抵押融资平台Lendf.me遭受黑客恶意攻击,数字货币损失价值可能高达2500万美金。

Lending protocol Lendf.me saw some $25 million in ether (ETH) and bitcoin (BTC) exit its wallets late Saturday and early Sunday after its money market pool was attacked. Lendf is one of two protocols supported by the dForce Foundation.

据熟悉类似平台系统构架的技术人员分析,本次攻击针对基于以太坊ERC-777协议发行的比特币等价数字货币”imBTC“,ERC-777协议支持的token被认为存在某种缺陷可导致多次重复取币而不能及时有效更新信息。可见,目前的去中心化金融平台仍存在较大的技术漏洞风险,损失挽回因为无中心化的权益关系将难以执行。
