bZx: The second attack is an Oracle operation attack, which is different from the previous one
2020-02-18 23:57
Defi协议bZx昨日再次遭受攻击。对此,BZX发推称,第二次攻击是一次Oracle操作攻击,与第一次攻击完全不同。攻击者从系统中获得了大约60万美元的净利润。Kyber上的sUSD储备金包含APR和Uniswap池。我们认为,攻击者能够同时操纵这两者,并绕过相关检查。我们将实施一项更改,允许交易者和借款方平仓。在此期间我们将加强协议安全以确保不会再次发生类似事件。另外,我们正在与Chainlink和其他Oracle网络合作,以创建更安全的Oracle网络和缩小协议可攻击范围。
据此前报道,Bitcoinist指出,bZx遭受二次攻击表明需要对DeFi智能合约进行彻底审计。
