Password in the dark web

McAfee warned about a password leak in the dark web.
The only password I had with that length of characters was this site.
I had created that password many years ago when I was young and dumb (today I am just dumb).
And of course the password did not abide to the minimum length of a decent password. With brute force it would take a few seconds to get that leaked password with modern technology.
So I am not saying that your password is compromised or that this site was hacked. It is clear to me that someone at least attempted to at least brute force this website with my email.
I tell you just in case. I already changed my password to make it compliant with modern requirements.
