Wu said that he learned that Ethereum Layer 2 protocol Loopring tweeted that some Loopring smart wallets suffered a security vulnerability attack a few hours ago. The attack specifically targeted wallets with only one Guardian, especially wallets using Loopring's official Guardian. The hacker initiated a recovery process, impersonating the wallet owner to reset ownership and withdraw assets. Currently, Guardian-related and 2FA-related operations are temporarily suspended, and we are working with law enforcement and professional security teams to track down the attacker.
