Zacks data breach
I have been notified by Have I Been Pwned that my data is in the Zacks data breach. As far as I know, I have never set up an account with Zacks. I assume that some site that I have an account with uses Zacks as an underlying service for providing financial research data.
Does anyone know a way to find out what site that I have an account with might use Zacks as an underlying service? I don't know how to find where I need to change my password.
