Haveibeenpwned.com has added a database dump of almost 101 million Evite users who had their information exposed when attackers gained unauthorized access to their servers. No financial information or social security numbers were part of the breach. The original leaked database was being sold on the online underground market named Dream Market. This site has since been shut down, so it is not currently known where or if this larger Evite database is being sold online as well. Anyone who has an Evite account is advised to change their password.
