FuzzLand: Prevented over $6.5 million in assets on Sonne Finance from being further attacked by hackers with just $100
ChainCatcher news, a member of the blockchain security company FuzzLand stated on the X platform that the team prevented over $6.5 million in assets on Sonne Finance from being further attacked by hackers with just $100.Specifically, the Optimism native lending protocol Sonne, based on Compound, has a common Compound V2 vulnerability where attackers can perform precision loss attacks when there are uninitialized new pools (soVELO). FuzzLand immediately detected the attack after the hacker's initial strike and found that the attacker held a soVELO position, which made it impossible for them to exploit it without liquidating the precision loss. FuzzLand then exchanged $100 for some VELO and added it to the soVELO pool, rendering the vulnerability no longer exploitable, thus protecting approximately $6.5 million of the remaining fund pool from being reused.Previous report mentioned that earlier today, the Sonne Finance protocol on the OP chain was attacked by a hacker using a flash loan, resulting in approximately $20 million in losses through multiple attacks.It is reported that FuzzLand is dedicated to automated auditing and on-chain real-time auditing, focusing on a model that reduces reliance on manual security audits through AI and fuzz testing + formal verification, and providing on-chain real-time firewalls for protocols or end users.
