Wu said that BlockSec Phalcon's investigation shows that the YO protocol experienced abnormal transactions on Ethereum, with approximately $3.84 million in stkGHO 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: malicious output quotes by the initiator that effectively disabled slippage protection; and an abnormal route in the executePath parameter, involving high transaction costs and a very thin liquidity pool, leading to significant fee extraction and severe price impact.
