 There are a lot of dark web monitoring services. I got an alert from Google about this whole AT&T thing. But, again, it wasn't confirmed that it was AT&T until just now. So AT&T now on their website as of March 30th, as I read this, they said that, yes, AT&T has determined that AT&T data-specific fields were contained in a data set released on the dark web. Source is still being assessed.
