MultiBit

How to recover your MultiBit wallet

Multibit is a thin Bitcoin client, which was available between the years 2014-2017. In 2017 it ceased all operations and users who have generated wallets using its software sometimes found themselves stranded without an option to move funds away from the wallet and spending their coins.

Multibit has had two versions, Multibit Classic and Multibit HD. Users for both wallets are now unable to spend any coins from any version of the wallet.

Recovering your Multibit password

If you've forgotten your wallet password, you can try and recover it. No one working at Multibit or their support team cannot access or recover the password for you as they do not store it but rather encrypt all sensitive information with the password you selected when you created your wallet

Manual recovery

The basic approach to recovering your password is to create an Excel sheet with all relevant and optional passwords that you might have used, then, expanding each option to multiple other options. For example, if you usually use the password Password123 then you may want to include Password1234 and Password111. After listing all options, you can copy and paste each option and try to decrypt your wallet via Blockchain.com's website. Don't worry - You can try as many times as you want since the decryption process happens in-browser and does not communicate anything back to their servers until you hit the correct password.

Recovering with BTCRecover

A more advanced approach is to use Brute Force or Dictionary attacks on your wallet. This will allow you automate a part of the process in case you could not find the correct password manually. BTCRecover is an open source software developed by gurnec (and currently maintained by 3rditeration) and can help you scale your cracking attempts.

Using BTCRecover requires some technical knowledge and has basically two ways to recover your password:

1. Using a dictionary attack - Requires you to create a long list of possible passwords in a text file and feed it to BTCRecover
2. Using a token file - Allows you to create structures of passwords that you might have used and attempt any password that matches the pattern you provided.

To install BTCRecover, follow the instructions listed in the instructions page

Using a dictionary attack

First, create a text file containing all possible passwords that you may have used for this wallet, place each password in a new line. Then, run the following command in your terminal:

python3 btcrecover.py --wallet multibit.wallet --passwordlist my-passwords.txt

Using a token list attack

Token lists can be really simple or really complex, depends on how you want to use them. To fully understand how token lists work, you can read this instruction page. To get back to our Password123 example, let's say we're not sure if we've capitalized the P or if we used 123/1234/111/123456 or any other combination of numbers. A good token to represent all of the possible options is the following

%[Pp]assword%1,6d

The above will generate passwords with an upper case and lower case P and will append any digits in the length of 1 to 6. Relevant candidates for the above token are:

Password123
Password111
password91874
password000000

To run your token list attack, simply use the following command after creating a file with all relevant tokens

python3 btcrecover.py --wallet multibit.wallet --tokenlist my-tokens.txt
