Bitcoin Owner Claims Claude AI Cracked Lost Wallet Password, Netting $400K in BTC

Summary

A pseudonymous X user, "Cprkrn," claimed that Anthropic's Claude AI helped recover a Bitcoin wallet containing 5 BTC, worth about $400,000, that had been inaccessible since 2015. The X thread, which went viral with over 6 million views, described using Claude to analyze old files from a college computer, eventually identifying a wallet file associated with a mnemonic phrase written in a notebook. Attempts with common recovery tools like btcrecover and Hashcat had failed prior to using Claude. Blockchain data confirmed that funds in the wallet had not moved since 2015 until the recovery. While screenshots suggested Claude assisted in organizing and analyzing data, there was no evidence that it broke cryptography or directly cracked the password. Experts posited that Claude’s actual role was forensic—sorting through historical files and surfacing relevant information, rather than cracking encryption. The story drew both intrigue and skepticism, with some online users arguing that Claude’s involvement was overstated and that the AI primarily aided in data organization, not technical decryption.
