The article explicitly mentions AI-powered coding agents scanning smart contracts faster than human teams, which is a clear AI system involvement. The expert's warning is about the potential for these AI systems to enable attackers to find vulnerabilities more effectively, which could plausibly lead to significant financial harm in DeFi protocols. Although large financial losses from hacks are reported, the article attributes most of these to operational failures and social engineering rather than direct AI exploitation. Therefore, no direct or indirect harm caused by AI systems is confirmed. The event describes a credible risk scenario where AI use in offensive security could lead to future incidents, fitting the definition of an AI Hazard rather than an AI Incident. The article also includes differing opinions and potential positive uses of AI, but the main focus is on the warning of plausible future harm due to AI in DeFi security.
