A pseudonymous X user, Cprkrn, claimed that Anthropic's Claude AI helped recover a Bitcoin wallet containing 5 BTC, worth approximately $400,000, after being inaccessible since 2015. The viral thread, which amassed over 6 million views, detailed how Cprkrn had been locked out of the wallet for more than a decade after changing the password while in college. Despite years of attempts using tools like btcrecover and Hashcat, he was unable to regain access.
The breakthrough came when he uploaded old computer files to Claude, which identified a forgotten wallet.dat backup. Combined with a mnemonic phrase Cprkrn had written down, the AI helped decrypt the file and reveal the original password: "lol420fuckthePOLICE!*:)". Cprkrn attributed the lockout to being "stoned" when he changed the password, calling the solution "the most obvious opening ever".
The incident sparked widespread debate. Recovery experts clarified that Claude did not break Bitcoin's encryption; instead, it performed forensic analysis of historical data to locate and correlate the old wallet file. Reddit users expressed skepticism, some accusing the posts of overstating Claude's role. "This isn't so much a password cracking thing as it is a forensics sorting," one expert told Decrypt. The story highlights growing interest in AI's potential for complex digital forensic tasks, especially following the launch of Anthropic's Claude Mythos model, but also underscores the public's mixed understanding of AI capabilities.
