แพลตฟอร์ม DeFi “Opyn” ถูกโจมตีด้วย Flash loans ได้เงินไปกว่า 11 ล้านบาท

my smol brain 🤏🧠

attackers used the exploit below on @opyn_

looks like they started with flashloans to buy oETH from uniswap to exercise

then they realized fuckit they should just mint oETH themselves

waiting for someone else to confirm and also do the bodycount ☠️ https://t.co/bt2AsWFBue

Here is an overview of the incident affecting ETH Put contracts. No other contracts are affected. ~371k USDC was lost. We worked with @samczsun to whitehack, securing ~439k USDC. Affected users, please see below. Full post-mortem coming in next few days.https://t.co/ILNutAiqfU

Hey all, it seems like there has been an issue with some oTokens contracts. We are working hard on understanding this issue so we can let help users as best we can. We have removed liquidity from Uniswap in the mean time. Would be best to not open new vaults at the moment.
