According to TechFlow, Loopring tweeted that its smart wallet was attacked a few hours ago. The attacker took advantage of a wallet with only one guardian, specifically the Loopring official guardian. The attacker successfully took advantage of Loopring's two-step verification service and impersonated the wallet owner to perform the recovery process, and then transferred the assets.

Loopring has temporarily suspended Guardian and two-step verification operations and is working with Mist security experts to investigate and is working with law enforcement and security teams to track down the attacker. If you have any information that could help track down the attacker, please share it with them.
