zkLink has established a fund recovery bounty program in response to the recent security incident affecting zkLink Nova. Those providing valid leads may receive up to the recovered amount 20%as a reward. Attackers who return all funds may retain 20%as a white-hat bounty.
zkLink confirms that Nova's Arbitrator contracts on Ethereum and Optimism remain under attack, and the technical team is responding. The official team stated that returning the funds will earn a 20% white-hat bounty.
Cysic said that the attacker unauthorizedly minted 10000000 tokens CYS and subsequently profited ETH, while proposing that the attacker be allowed to retain approximately 10%as a bounty, and requiring 72 the remaining funds to be returned within hours. Failure to meet the deadline will result in escalation and a request for law-enforcement intervention.
