We have been actively investigating this report since it came in. However, we have found no evidence of a recent breach thus far. We will be continuing our investigation on this end, but we wanted to provide our initial analysis results as quickly as possible.
While we haven't completed a thorough analysis yet, this may be a false positive. Another possibility is this pertains to data that was potentially exposed over 15 years ago, after which we significantly tightened our security. For more details of the latter event, please see this post:

As a precaution, we encourage everyone to consider changing their password and ensure that it is different from any other password you use elsewhere. To simplify doing that, you might consider using a password manager that ensures you use unique passwords for all websites and services to which you subscribe.
