defi吸血鬼挖矿和rug pull
8月底,SushiSwap的传奇开始了,并且产生了“吸血鬼挖矿”和“rug pull” (指一些项目通过包装自己来骗取用户质押和投资,随后立刻卷款逃跑)。SushiSwap的匿名创始人“Chef Nomi”出售了价值800万美元的SUSHI代币,导致SUSHI的价格暴跌。几天后,FTX交易所首席执行官Sam Bankman-Fried拯救了该协议,通过一个多签名智能合约,他被一个DeFi鲸鱼联盟移交了控制权。最终,所有的资金都返还给了该协议的开发者基金。

  2017年山寨币繁荣期间,rug pull继续推出Pizza和Hotdog等一系列DeFi克隆币。这些代币的价格在几小时,有时甚至几分钟内就大幅飙升和暴跌。

  在10月中旬,交易员纷纷把资金发送到了一份未经审计和发布的智能合约中,这份合约来自DeFi协议Yearn Finance的创始人Andre Cronje。在Cronje在推特上发布了关于新的“游戏多元宇宙”的预告片后的几个小时内,智能合约Eminence Finance遭到黑客攻击,损失了1500万美元。这名黑客返还了大约800万美元,但保留了剩余的资金,这促使心怀不满的交易员就损失的资金对Yearn团队提起了法律诉讼。

  10月底,针对Harvest Finance协议的一起复杂的闪电贷套利攻击导致7分钟内损失了大约2400万美元的稳定币。这次攻击引发了一项争论:这些对系统设计的利用是否可以被视为黑客攻击。

  11月对Akropolis来说是特别痛苦的一个月,因为黑客盗走了价值200万美元的DAI稳定币,Akropolis不得不“暂停协议”。Value DeFi协议在一次常见的闪电贷攻击中损失了600万美元,稳定币项目Origin Dollar损失了700万美元,Pickle Finance在一个复杂漏洞中损失了价值2000万美元的DAI。

  12月中旬的一起个人攻击打破了利用协议系统漏洞的模式。DeFi保险协议Nexus Mutual创始人Hugh Karp的MetaMask钱包损失了800万美元,原因是一名黑客成功入侵了他的电脑,伪造了一笔交易。这些类型的攻击通常不太常见,因为它们涉及到某种程度的社会工程。

  到目前为止,今年报道的最后一次闪电贷攻击是12月18日Warp Finance遭遇黑客入侵,损失了800万美元。

  许多零售交易员和投资者也遭遇了网络钓鱼诈骗,而在2020年,约272,000名Ledger买家的个人信息遭到黑客攻击后,Ledger硬件钱包所有者也成为了攻击目标。
