1  Bitcoin / Bitcoin Technical Support / Found 3 MultiBit HD Wallet Backup Files (mbhd-[..].zip.aes) + 12-Word Seed on: December 15, 2024, 05:25:54 PM
Hello everyone,

While going through an old hard drive, I discovered a folder containing three MultiBit HD Wallet backup files (mbhd-[...].zip.aes) and a screenshot of a 12-word seed phrase along with a datestamp (XXX/XX).





I remember having a small amount of BTC associated with one of these accounts. However, when I tried importing the seed phrase into Electrum, the generated accounts were empty and showed zero transactions.

After some research, I found that certain releases of MultiBit HD had an incorrect implementation of BIP32 (https://github.com/Multibit-Legacy/multibit-hd/issues/445). This might be why I'm unable to restore the wallet using the seed phrase alone.

From what I've read, it's possible to decrypt the backup files using the seed phrase. However, I also came across a post from an old MultiBit HD dev stating that the AES key used for decryption is derived from the seed phrase. I'm unsure how the seed phrase is transformed into the AES key ("MultiBit HD dev here. The cloud backups are encrypted with an AES key derived from the wallet words only, not the password." : https://bitcoin.stackexchange.com/questions/38948/how-do-i-restore-a-wallet-from-a-backup-file-in-multibit-hd#comment45918_38966 ).

Some additional information:

- I do not have access to the original MultiBit HD software

- I do not remember the addresses

- The folder name is "BitCoinCloud"

Has anyone successfully restored funds from MultiBit HD backups under these circumstances?

Thank you in advance for your help!
