Wu said that BlockSec Phalcon's investigation shows that the YO protocol experienced an abnormal exchange on Ethereum, where approximately $3.84 million worth of stkGHO was exchanged for only about $122,000 USDC; the team has purchased GHO and redeposited stkGHO into the vault; the investigation attributes the discrepancy to two factors: the initiator's malicious output quote effectively disabling slippage protection; and an abnormal route in the executePath parameter, involving extremely high transaction fees and a very thin liquidity pool, leading to significant fee extraction and severe price impact.
