While monitoring exposed password databases we found a leaked database that contained 178 compromised credentials of CleanTalk users among other data. These emails/passwords were compromised some time ago and after that were used to create a CleanTalk account by their owners. As soon as we found this potential vulnerability – we immediately reset passwords for all CleanTalk users related to these email addresses.
