Sonne Finance Falls Victim to $20 Million Hack
Sonne Finance protocol, operating on the Optimism platform, recently suffered a hacker attack that resulted in the theft of $20 million. The attack exploited a vulnerability in the Compound v2 fork, to which Sonne Finance belongs. The hacker used a flash loan attack method to bypass the protocol’s security measures.
Immediate Actions Taken by Sonne Finance Team
Following the breach, the Sonne Finance team suspended the protocol on the Optimism L2 solution to prevent further losses. Despite following all security recommendations, the protocol was in the process of adding support for the new token VELO and integrating lending conditions, which gave the hacker the opportunity to carry out their actions.
Users’ Prompt Alert Prevents Additional Theft
Thanks to timely alerts from protocol users who noticed suspicious activity, an additional $6 million theft was prevented. An active investigation is currently underway, and the Sonne Finance team has offered a reward to the hacker for returning the stolen funds. In exchange for returning the funds, the hacker will not be pursued criminally.
It is still unclear whether the hacker will agree to return the funds and what amount of compensation they may receive. Given the scale of the theft, it is assumed that the hacker will not settle for a small sum as compensation. Further updates on the situation will follow.
