Ostium said an attacker stole $23.75 million from its liquidity provider vault after compromising off-chain price feed infrastructure and submitting fake price reports to generate artificial profits. The platform paused trading, confirmed trader collateral was not stolen, and said the stolen USDC was later swapped into Ethereum and partially sent to Tornado Cash. #Ostium #Arbitrum #USDC #PeckShieldAlert #TornadoCash
