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?
You could use something like simplelogin.io to create aliases.
Integrates with password managers like Bitwarden nicely to generate aliases.
I think many other services support the + trick though too. The downside is that spammers know the + trick and can find out your base email easily; they can’t if you use an alias.
