A known reentrancy vulnerability was exploited on Uniswap against the imBTC. liquidity pool. Around 24 hours later, at Apr-19–2020 12:58:43 AM +UTC, a similar hack occurred on Lendf.Me.” reads the analysis published by Blockchain security firm PeckShield. “Technically, the main logic behind these two incidents is the fact that the implementation of ERC777-compatible transferFrom() has a callback mechanism, which allows the attacker to utterly hijack the transaction and perform additional illicit operations (via _callTokensToSend()) before the balance is really updated (i.e., inside _move()). Uniswap was hacked and lost 1278 ETH.
