I’m no cryptography expert, but is it that big of a deal if hackers made away with the encrypted password data? LastPass says they encrypt with AES-256 so I figure that’s not getting cracked anytime this century. I’m more concerned about the unencrypted data, e.g. the Website URLs
The problem was that they were grandfathering existing users without notification every time they increased their PBKDF2 iterations. I think the current recommendation is 100,100 iterations, and LastPass was implementing that for new users. But it wasn’t updating that for existing users, resulting in some having as few as 5000 iterations, making that user’s encrypted data much easier to crack. You could change the iterations in the settings, but that required knowing that you needed to do this, and LastPass should have either changed it automatically or notified users that they needed to change it.
I was paying LastPass to be the security expert so I didn’t have to learn all the ins and outs of data encryption, and they failed at that task.
