Few things in life are as private as our romantic entanglements. So with hackers announcing they’ve made off with as many as 37 million records from the parent company of extramarital dating site AshleyMadison.com, you can be sure there are plenty of people sweating over the potential fallout.

The group, which calls itself “The Impact Team,” released a statement on July 20 saying that it has gained access to the databases of Canada-based Avid Life Media, which runs Ashley Madison and other dating sites. The hackers said that if ALM does not comply with its demand to shut down services, it will release private information on its clientele. In addition to the notification, the group has also released a small portion of the data stolen as a demonstration of its intent.
