After further investigation with @danfinlay and team, it appears that the compromise was due to a registrar that has locked up the email domain. 

It appears to have only affected this one account. 

Some more details in thread about what we're doing next.

Latest update

No evidence to believe there is a wider security issue.

Will ship a few additional improvements for boosting the security of individual accounts this week.

This looks just like the issue is in accessing the email. I don't think anything has to do with Warpcast, but any security improvement is great.
