zkLink: Nova contract has been under continuous attack, willing to offer a 20% white hat bounty

The aggregation Rollup infrastructure zkLink announced that it has confirmed ongoing attacks on its aggregation Layer 3 network zkLink Nova's Arbitrator contracts on Ethereum and Optimism. zkLink stated that the technical team is urgently controlling the situation to prevent further losses and will update the community on progress.

zkLink calls on relevant parties to cease further exploitation of zkLink Nova's contracts across various chains and to return the affected funds. The project team stated that if the other party cooperates in returning the funds, they are prepared to offer a 20% white hat bounty, and no further action will be taken after the funds are returned.

The security agency Blockaid previously monitored that attackers injected forged batch roots into Ethereum through public relays, and then completed ETH and ERC-20 withdrawals from zkLink Nova's L1 custody contract. At that time, the total loss from L1 ETH custody and ERC-20 bridge was approximately $786,000, and the attack is still ongoing.
