Dunno if other people have a faster way of finding out about potential data breaches, but for me, the original Bleeping Computer article about this showed up on my newsfeed and that’s how I found out about it, followed a few hours later by other sites parroting the same news while quoting the BC article. It wasn’t till I saw this post that I learned this breach is a fake, though. So, I’d say just keep an eye on your newsfeed and if you see something there, check any tech news communities and other relevant social media communities that you’re a part of for the same news and for further details.

Edit: There’s also sites like Have I Been Pwned where you can put in your email and get information on every known data breach involving your email address. The site can also notify you about any new data breaches where your email showed up in the affected data.
