Yuga Labs Vice President reminds: Immediately revoke PPV2 related authorization

According to Quit monitoring, the Payment Processor V2 (PPV2) vulnerability attack is still ongoing. Even if users are not affected by the incident, as long as the relevant authorization has not been revoked, assets may still be at risk, and it is recommended to revoke the authorization immediately.

About 1 hour ago, a certain address lost 0.15246 WETH in the next block after accepting a quote and receiving funds. The attacker paid 99% of it as a tip to Titan Builder, keeping only about 0.0015 ETH, which is almost impossible to recover through front-running. Quit suggests that OpenSea should check whether there are still risk authorizations before users accept quotes and require users to revoke them first; when transferring NFTs, it should also check whether the receiving address has relevant authorizations left.
