On their website, go to the sign in screen and click “Need help signing in”. Go through the prompts and watch the person’s username, and the legal name of all their employers (who have ever used ADP) appear on the screen.
Note: Whether or not you select “my current employer uses ADP”, it will still show you the full list of both current and previous employers (who use ADP).
From there, it is remarkably easy to gain access to paycheck information if you are a grocer, a landlord, a retailer, or anyone of the 2737429193 entities who may have a little extra data on them.
Edit: To address some of the comments, I feel I need to clear something up. I’m not saying this is some authoritarian configuration error ADP messed up on. It’s a standard login that works conveniently for ADP and also happens to be negligent in privacy protection. And it’s most likely completely legal for most people in the U.S.
I hear you, but in the last year I’ve begun wondering if full public disclosure isn’t a better way to go these days.
The sheer volume of breaches is overwhelming and in my experience (of over 40 years as an ICT professional) many companies sweep their failures under the carpet, hide behind crisis management teams and marketing speak, and ridicule those bringing issues to their attention.
Their disclosure is abysmal if it’s made at all and there are precious few who reveal precisely what data was exfiltrated or how the issue was remediated.
This way anyone can verify the issue and companies cannot hide, everyone sees precisely what’s leaked and can act accordingly.
If you know of a more effective way, I’d love to hear it.
I hear this. Stuff this egregious they are not even trying to begin with.
Making the attempt at responsible disclosure is still more effective.
Effective for whom?
The users who’s data was disclosed, or the company that made the disclosure?
Well, this leak is out there now for whoever decided to use it. And it’s being publicized. That doesn’t seem good for the people having their payroll data leaked.
Hey, now. Don’t go blaming the person who is calling attention to negligence of another. 5 years ago, ADP had user support service to handle login issues. But with the diminishing right to privacy in recent years, it is much more convenient for them to simply give the information away.
Everyone involved.
