One hour later, a hacker exploited a vulnerability in the bad code of 0xbadc0de, which allowed them to withdraw all of the ETH in the contract: not just the ETH they'd recently earned in the huge trade, but all 1,101 ETH (~$1.5 million).
The bot operator subsequently sent a message to the thief via an Ethereum transaction, writing that if the thief returned the funds, they would give them 20% as a "bounty". Otherwise, they wrote, "we will have no choice but to pursue accordingly with everything in our power with the appropriate authorities to retrieve our funds". The thief replied by mimicking the message, writing, "What about normal people who you have mev'ed and literally fucked them? Will you return them?" and suggesting that if they returned all of the funds they'd extracted, the thief would pay them 1%.
