Other data exposed include – in "encrypted" form – hashed and salted passwords
Right, so you encrypted your users passwords so that they couldn't be misused after a data breach. But it never occurred to you to encrypt their names, addresses, telephone numbers, email, because you didn't realise that these are also commonly used for phishing attacks when they get stolen.
20 years I've been informing companies of this problem, and imploring them to encrypt a lot more of the personal data they hold. And still I encounter the shrug of the shoulders and get told that they don't think it's that important and will make more work for them. Still, this story is one more example to add to my file of reasons why they're wrong.
