By default, early versions of Bitcoin Core did encrypt the wallet.dat file. If someone obtains a copy of an unencrypted wallet.dat file, they can instantly load it into their own Bitcoin client and drain the funds. Even if the file is encrypted, a hacker can download it and run aggressive, automated brute-force attacks offline without the owner ever knowing. The Anatomy of a Google Dork

Attackers who obtain encrypted wallet.dat files often attempt to crack the passwords using tools like bitcoin2john.py and hashcat . The process involves extracting the password hash from the wallet.dat file and then running dictionary or brute-force attacks against it. While strong passwords make this impractical, many users have historically chosen weak or short passwords. It is noted that if a password exceeds 13-14 characters or contains more than 6 words, it becomes extremely difficult to crack without massive computational resources. Index-of-bitcoin-wallet-dat
