In April 2026, significant DeFi attacks on Drift Protocol and Kelp DAO resulted in losses nearing $600 million, prompting $9 billion in capital outflows from platforms like Aave. Investigations suggest North Korean hacker groups may be leveraging AI for target selection and attack planning. Aneirin Flynn, CEO of Failsafe, highlighted that AI has drastically reduced the time needed to identify blockchain vulnerabilities from months to mere hours. A report indicates that Anthropic has withheld full access to its AI model Mythos due to cybersecurity concerns, as it can detect large-scale zero-day vulnerabilities. Research suggests that by 2025, over half of blockchain attacks could be autonomously executed by AI, underscoring the growing threat of AI in cyber warfare.
