Hidden wallet discovered — Bitcoin Core (2022)

Indeterminate

Case description

ReWallet, a wallet recovery service, documented in 2022 that the most common cases they received involved forgotten Bitcoin Core wallet.dat passwords, often on wallets created between 2012 and 2017 when Bitcoin was inexpensive and the password had seemed unimportant. Owners rediscovering old wallets as Bitcoin's price rose faced recovery attempts using brute-force tools. Success depended heavily on whether the original password had a guessable pattern or length, and whether the owner could provide hints.
