The threat actor was also able to copy a backup of customer vault data from the encrypted storage container which is stored in a proprietary binary format that contains both unencrypted data, such as website URLs, as well as fully-encrypted sensitive fields such as website usernames and passwords, secure notes, and form-filled data.

As a reminder, the master password is never known to LastPass and is not stored or maintained by LastPass.

My guess is that many LastPass users do not have strong master passwords, even though the compromise of your encrypted password file should be part of your threat model.

If that's true, it means that LastPass has some backdoor-possibly unintentional-into the password databases that the hackers are accessing.

If you're changing password managers, look at my own Password Safe.
