Octane Security said its AI tool identified a high-severity bug in Nethermind, the Ethereum client. Nethermind fixed the bug before it could be exploited, according to Octane. Nearly 40% of Ethereum validators rely on Nethermind, making an exploit potentially disruptive to block production and network liveness.
“This is one of the highest-stakes demonstrations yet of AI-led vulnerability research,” said Giovanni Vignone, founder and CEO of Octane Security. “AI has dramatically accelerated vulnerability research, enabling faster bug hypotheses, exploit verification, and production-grade reports.” The Ethereum Foundation awarded Octane a $50,000 bug bounty for reporting the issue.
It underscores how AI-enabled security reviews can rapidly identify critical flaws before deployment, helping to protect on-chain ecosystems. The case illustrates the evolving threat model for organizations placing code on-chain, where AI-assisted research accelerates discovery.
