My password manager told me that my info was leaked, including IP address, address, email, personal information, and phone number, in a data breach of eye4fraud.com. However, I don’t use eye4fraud, so it must have been a site that uses their services. I would like to change my login credentials on the site that shared my data with them (and stop using their service since they’re sharing my info with a security company that was breached), but I don’t know which site that was. I found this list of sites that use eye4fraud, but that list has over 1,600 entries. Other than reviewing every single sight on the list, is there a way of finding out which site that I use leaked my info?
Why would it be worthless? It’s still a valid, deliverable address to a real person (you). The only difference is the receiver knows which company sold their information AFAIK
No it’s not, because the whole point of it is so you can filter them out. Which is exactly what you do when you realize you’re getting email from someone you didn’t give that address to, and at which point it becomes worthless. But stripping out the plusses is trivial and yields an un-filterable address.
