Maybe it’s a naive question, but in many breach reports I see things like 'No passwords, private keys, or funds were exposed.' How come companies can usually protect that kind of data, but not emails, names, and other personal info?
Companies want the ability to use things like emails, names, and other data for user experiences (go to settings, see name and change it), advertising (target this address book for X ad), etc. So these are typically plaintext (oversimplified) and accessible by different systems while passwords or private keys have one use case only and can have a higher bar of protection.
