A user who forgot the password to 5 Bitcoin bought during his university years and could not touch his fortune for 11 years recovered his $400,000 (about 18 million TL) digital treasure thanks to Anthropic's AI Claude. The user — who shared the details on X under the handle "cprkrn" — managed to break a lock that even professional recovery teams had given up on, using AI's data-mining and code-analysis capabilities.
The story dates back to 2014-2015, when the user was a university student. He had updated the wallet password at that time but forgot to note the new credentials. Using only his old mnemonic phrase, @cprkrn tried to access the existing "wallet.dat" file — but the wallet's updated security layers no longer accepted his old keys. After years of fruitless waiting, he said he had spent $250 on professional crypto-recovery services without result.
Where traditional methods had failed, AI took over and reversed the process by analysing a massive pile of data on an old computer. The user uploaded his old notes, backups, and different "wallet.dat" versions to Claude. Among thousands of files, the AI identified a critical backup file created just before the password change, pinpointing the root cause. The most striking step came when Claude detected a technical flaw in the world-famous open-source recovery tool btcrecover: realising that the software was making a mistake in the key-password concatenation logic, Claude corrected the code path and re-optimised the process. As a result, the private keys were successfully exported in "Wallet Import Format" (WIF).
From a supply-chain perspective, this case shows that AI can demonstrate super-human combinatorial search capability for critical infrastructure debugging: what Claude did was not just brute-force password guessing — it found and fixed an internal logic bug in open-source software. This points to a broader theme: AI-assisted code-review for "edge-case" bugs in ERP systems, logistics optimisation engines, and supply chain planning software is becoming a practical tool. The operation, documented on social media with screenshots, shows that AI can be used not only to write text but also to debug complex cryptographic errors.
Key Takeaways:
1. @cprkrn recovered 5 Bitcoin ($400K) inaccessible for 11 years using Anthropic Claude.
2. Among backups, a critical file created just before the password change was identified.
3. Claude found and fixed a code bug in the open-source btcrecover tool.
4. Private keys exported in Wallet Import Format (WIF).
5. AI is becoming a practical tool for critical software debugging.
