I don't understand how to find out which specific sites had my data leaked. Without that I can't take any action. I'm subscribed to email alerts but the alert did not include any details like the article said it would.
Rent a domain Set up email Use a unique address for every website
I usually pick the domain of the website as the username part.
So if, say, I have email set up on lemmy.cafe and want to sign up to flatearth.com - I'd probably use flatearth.com@lemmy.cafe for an email address. If they ever leak it - I'll be reveiving spam sent to this address.
In the six years of hosting my own email I've only had one such occurence when namecheap got breached. It was nice being able to tell where the culprit was!
As another poster detailed, this is not a company that exposed your info: these credentials are all from stealer logs, which are logs of credentials stolen by keyloggers installed on machines. If your credentials were in this report, it means that you've entered that username and password on a machine with malware on it. Could be your personal machine, or it could be some other computer you've used.
That's true. My point was just that the important thing here is knowing personally which domains were affected so one can personally change those sets of credentials. If I don't know which of my credentials leaked then there's no value to me.
I was able to finally get access and did change the specific credential that had leaked (again, not assigning blame to any specific site here).
