CertiK CEO: AI is Turning DeFi Offense and Defense into an "Unfair Game"
Odaily Planet Daily News, CertiK Co-founder and CEO Ronghui Gu stated that AI tools are exacerbating the imbalance in DeFi security offense and defense, making it easier for attackers to discover vulnerabilities and replicate attack paths across different protocols.
He pointed out that the DeFi security situation in April of this year was particularly severe, with only 3 days without a hacker attack that month. DeFi protocols suffered cumulative losses exceeding $690 million. Excluding the Bybit attack in February 2025, April has become the month with the highest losses from DeFi hacks since March 2022.
Ronghui Gu believes that attackers can concentrate massive computational power to repeatedly test a single protocol, whereas security companies need to serve multiple clients simultaneously with scattered resources, naturally putting the defenders at a disadvantage. At the same time, the focus of recent attacks is shifting from smart contract vulnerabilities to operational security and supply chain weaknesses.
He emphasized that even if AI fails to find vulnerabilities for a long time, it does not prove the code is completely secure; under current technical conditions, formal verification remains a more reliable method of ensuring security.
