CertiK co-founder and CEO Ronghui Gu stated that AI is exacerbating the DeFi attack defense imbalance, making it easier for attackers to discover vulnerabilities and replicate attack paths. It pointed out that in April 2026, there were only three days without any hacking incidents, and DeFi protocols suffered monthly losses exceeding $690 million; If Bybit events are excluded, it will be the month with the highest loss since March 2022. Gu stated that with the improvement of audit standards for smart contracts, attackers are increasingly turning to supply chain, operational security, and infrastructure level attacks, and mentioned that incidents such as Drift Protocol and Kelp DAO involve related issues. He also warned that the legal controversy caused by the Arbitrum asset freeze may make the coordination mechanism for future industry joint freezing and recovery of stolen assets more complex. （The Block）https://(wublock123.com)/news/certik-ceo-ai-exacerbates-defi-security-supply-chain-ops-vulnerabilities-61100
