How to Avoid the Uncomfortable Feeling of Hacking Your Own Bitcoin WalletĪs security experts have endlessly emphasized, humans are the weakest link in the strength of any security. Hackers obviously exploited the vulnerability of brainwallets, draining 884 brain wallet accounts of 1,806 Bitcoins. In a research paper entitled “ Speed Optimizations in Bitcoin Key Recovery Attacks” Nicolas Courtois, Guangyan Song, and Ryan Castellucci demonstrated that they could recover 18,000 Bitcoin wallet passwords using their technique. As you might have guessed, they did.Ĭracking into Bitcoin wallets isn't new white-hat hacker Ryan Castellucci has done it before. A project called the Large Bitcoin Collider designed to hint at cryptographic collisions has been able to generate more than 3,000 trillion private keys and check them against existing Bitcoin addresses to see if they contain Bitcoin. You aren’t the first and won’t be the last to crack a Bitcoin wallet. Of course, you have access to more info than a hacker might, so putting together a list of passwords can streamline the process and could increase the success rate.

With John the Ripper you'll need to inform the software of what it is that you want crack, specify the hash you'd like to decrypt, choose the word list to use for the attack, and, finally, specify the number of CPU cores to use. It might be worth looking into how password recovery tools work before downloading the software of your choice. Two of the most popular are John the Ripper or Hashcat, so pick one that suits your needs. Without a password cracking tool, however, the wallet won't open.

Still, there is one thing you need to consider: using this method means the security of your Bitcoin wallet now depends on how unpredictable your password is. Since SHA-256 is a deterministic method, users can always use the same password to recreate their private key. The key is turned into a 256-bit number using the SHA-256 hash algorithm.
