Our team has noticed a suspicious activity which has targeted multiple accounts. The wrongdoer is trying to brute-force a correct 2FA code in order to access CEX.IO accounts.
It is a humble request for you to check out your security settings in terms of the following:
1) Make sure your email and CEX.IO passwords are strong enough and different from each other.
2) In case you are getting unauthorized notifications for 2FA text messages(not requested by you), it means that your email and CEX.IO account are compromised. It is highly recommended to logout of all the active email sessions and change your password immediately.
If you have any questions, please contact our support team.
