A Bitcoin holder, known as cprkrn, successfully recovered 5 BTC from a wallet inaccessible for over 11 years, using Anthropic's Claude AI. The recovery, valued at nearly $400,000 with Bitcoin prices nearing $79,622, was achieved by analyzing old computer files and utilizing the open-source tool btcrecover. The user had previously lost access after changing their Blockchain.com wallet password. Claude AI identified a backup of an old Bitcoin wallet among university-era files, enabling the user to decrypt the wallet and access their private keys. This breakthrough followed numerous failed attempts, including commercial data recovery services and brute-force attacks. The incident has sparked interest in AI's role in cryptocurrency recovery, though it raises security concerns about sharing sensitive data with AI systems.
