Putting a password and emailing the admin would solve the password problem.
But I agree doing anything is probably illegal. I would leave it... not worth hassle of wearing the superman cape.
Emails have a bunch of info in the headers, so there is more meta-data in the email it self.
Neither is perfect for finding the culprit but one scenario has zero meta-data and the other has some.
That still doesn't justify vandalism.
They secured it, and somehow managed to make it publicly accessible again without password, this time it got hit by this attack.
Honestly this is like if a company decides to keep their paper records with my information on a public side walk, and somebody saw that and decided to bring them to the landfill.
Is it legal or fair? In a perfect world no, but at this point the company is not blameless.
No. The equivalent would be exploiting their buildings weakness to cause them to collapse - maybe with people in them.
Pointing out a vulnerability is not the same as demonstrating it.
That said, a demonstration will get their attention more.
This attack is indiscriminate and is without warning, so it eliminates the possibility for database owners to fix the problem in good faith.
I got doxxed with the Equifax breach. How many other companies in the world will take someone's word that they are me based on that data, and what potential is there for my life amongst millions of others to go completely sideways because of companies who won't addmit the systems are broken?
I say the house is already burning, but maybe throwing some fireworks into the blaze will convince the right parties to finally put the damn fire out.
Beyond sick and tired of breach after breach after breach after "oh, there were millions of voter records showing publicly" "no, <insert product name> defaults to no security"
