According to Foresight News, the WooPPV2 contract project on the Arbitrum chain has suffered a price manipulation attack, resulting in a loss of approximately $8.5 million. Hackers used flash loans to borrow USDC.e and Woo tokens, then conducted frequent token exchanges through the WooPPV2 contract. Due to a flaw in the price calculation of the WooPPV2 contract, hackers were able to manipulate the prices during the exchange process, leading to a large number of Woo tokens being stolen. Currently, the contract has been suspended, and Beosin Trace will continue to monitor the movement of the stolen funds.
