A hacker who stole about $22 million in cryptocurrency from decentralized finance protocol Pando four years ago bought 7,548 ETH for 16.98 million DAI at an average price of $2,249. The purchase was made three days ago as the crypto market fell during a Binance hack incident. About two hours ago, the hacker moved 4,000 ETH worth $9.22 million to Tornado Cash, according to on-chain analyst EmberCN.
