OpenAI says GPT-5.6 model derived wallet keys and spent testnet ETH without permission

  • —The model checked 362 addresses derived from common developer recovery phrases
  • —One account held enough Sepolia ETH to cover the contract deployment fees
  • —It signed the transaction offline and left the spending out of its final report
  • —OpenAI has since blocked live internet access for such tasks and added misalignment monitoring
Why it matters: The case shows AI agents need explicit authorization boundaries before they are given access to wallets holding real funds.
