AI Security Agent Identifies Vulnerabilities in DeFi Smart Contracts
- A specialized AI security agent detected vulnerabilities in 92% of exploited DeFi smart contracts.
- The study evaluated 90 smart contracts that were exploited between October and early 2026, leading to verified losses of $228 million.
- The AI system flagged vulnerabilities linked to $96.8 million in exploit value, outperforming a baseline GPT-5.1-based coding agent which detected only 34%.
- The average cost for an AI-powered exploit attempt is approximately $1.22 per contract, facilitating large-scale scanning.
- Cecuro’s benchmark highlights that many teams depend on general-purpose AI tools, potentially overlooking complex vulnerabilities.
The findings indicate significant gaps in current security measures as many previously audited contracts were still exploited, emphasizing the need for enhanced defensive strategies against evolving threats.
This research shows that a dedicated AI approach can detect vulnerabilities in a majority of cases, with the specialized system identifying issues tied to $96.8 million compared to just $7.5 million by its baseline counterpart.
