Earlier today, the majority of our users received an email containing the email addresses of other users in the ‘to’ field. This was a general email update about upcoming changes to the weighting of our indices.
We are deeply sorry for the concern this has caused to our users. The issue was caused by an error in the software used to send emails. As soon as we were made aware of the issue, we immediately prevented further emails from being sent and have since addressed the issue to ensure this does not happen again.
BitMEX takes the privacy and security of our users very seriously. We are working around the clock to establish communication with all our users to provide any assistance and to ensure the continued safety of their account.
Beyond email addresses, at no point during this issue has any personal data or account information been disclosed.
