An X user said he recovered a Bitcoin wallet holding 5 BTC, worth about $400,000 by the article’s estimate, after it had been inaccessible for 11 years. The recovery reportedly used Claude AI, files from an old laptop, and the open-source tool btcrecover.
The account behind the story is @cprkrn. He said that while in college he changed the wallet password while intoxicated and never wrote it down, leaving the Bitcoin locked for more than a decade. He had previously tried 7 trillion password combinations without success.
Old backup file became the turning point
According to the post, the breakthrough came on May 13, 2026. After reviewing files from the old laptop and the wallet situation, Claude did not simply brute-force guesses. It located a wallet.dat backup created before the password had been changed, which still contained the original credentials.
The article says the mnemonic string was “lol420fuckthePOLICE!*:)”. Claude then fixed errors in the recovery software, ran the decryption process, and unlocked the wallet.
btcrecover handled the recovery process
The recovery relied on btcrecover, a free open-source program built to help restore wallet access. The software starts from the user’s best available guess, then generates large numbers of variations by correcting typos, swapping words, and testing different formats before checking them against the wallet data.
The report says Claude used btcrecover’s seedrecover.py script in a custom setup. It combined the old backup file with partial password information, corrected bugs that had blocked earlier attempts, and completed the recovery.
The same workflow could aid attackers
The story is drawing attention for another reason. The same capabilities used here—file scanning, debugging recovery tools, password pattern matching, and decryption guidance—could also be used against other wallet holders if an attacker gains partial access to their files.
The source article also points to growing AI-assisted crypto recovery scams. It cited one real case in which $500,000 was stolen through an AI-assisted attack. Fake support messages, cloned voices, and phishing links made to look legitimate can all become cheaper and easier to deploy with AI.
Weak backup habits remain a major problem
The article says a properly generated 24-word random seed phrase remains nearly impossible to crack. The risk comes from users who choose memorable phrases, skip extra passwords, or store backups in unsafe locations. Those weak points can be found quickly.
It also notes that as AI tools begin to handle wallets for trading and payments, a single bad command could empty an account without direct human action. In this case, the owner got his funds back. The broader warning is harder to ignore: tools that recover lost wallets can also be used to drain them.
