In a concerning development, several Loopring smart wallets have been compromised due to a security vulnerability. The attackers exploited wallets that only had one guardian, specifically the official Loopring guardian. The hackers initiated the recovery process, impersonating the wallet owners to reset ownership and extract assets.

The attack was successful due to the hackers' ability to infiltrate Loopring's 2FA service. By posing as the wallet owners, they were able to gain recovery approval from the official guardian. This allowed them to transfer assets out of the affected wallets, causing significant financial losses for the victims.

Loopring has taken immediate action to address the situation. They are actively collaborating with Mist security experts to determine how their 2FA service was breached. To protect users, operations related to Guardian and 2FA have been temporarily suspended. Loopring is also working with law enforcement agencies and professional security teams to track down the perpetrators and bring them to justice.

The hacker addresses involved in the attack are: 0x44f887cfbd667cb2042dd55ab1d8951c94bb0102 and 0xbacef3a142e39f14f4f15e22e9248ee4141af18f. These addresses have been identified as the ones used by the attackers to carry out the theft.

As the investigation continues, Loopring has promised to provide regular updates to their community. They are committed to ensuring the security of their platform and restoring trust in their ecosystem. This incident serves as a reminder of the importance of robust security measures and the need for constant vigilance in the ever-evolving world of cryptocurrency.
