On November 18th, OneKey Security Lab issued a security warning. Multiple users of the Dexx trading platform reported abnormal login attempts on their associated email accounts. OneKey recommends that users take immediate security measures, especially for those who use the same password for logging in to Dexx and their email: 1) immediately change the password for all Web2 accounts that use the same password; 2) completely abandon any leaked password combinations; 3) pay special attention to the security of email accounts that contain sensitive information and are associated with multiple authentications.
