Yesterday, two hacks on decentralized finance (DeFi) protocols netted a total of over $5 million, with a further $5 million siphoned off from compromised wallets on Wednesday.

He said the bot was not designed for Ethervista and that, “both the bot and us did not know we are hacking Ethervista.” Our bot unconsciously hacked @ethervista hundreds of times over the last two d...
