Binance has told its customers to take precautions as BitMEX announces a mass leak of its users email addresses from an internal error.
BitMEX Displays Private Data in Mass Email
Recently, BitMEX users discovered that they could openly view the email addresses of other users after they received an official email related to an update. BitMEX sent the email to everyone and mistakenly listed all the email addresses in carbon copy (CC) rather than in blind carbon copy (BCC), which allowed all of the addresses to be seen.
BitMEX just doxxed its users in the most outrageously incompetent way imaginable: forgetting to use blind copy on mass email. Someone must be cleaning out their desk already. https://t.co/KmARzImxnk

The incident raised privacy concerns, with some observers arguing that a simple apology will not be enough.
Nevertheless, so far, BitMEX presented its apologies, admitting in an official statement that it was aware of the situation and is investigating the issue. The exchange said:
Our team have acted immediately to contain the issue and we are taking steps to understand the extent of the impact. Rest assured that we are doing everything we can to identify the root cause of the fault and we will be in touch with any users affected by the issue.
Binance Reaches Out to its Users
Victims of the leak should take protective measures and change their email addresses on BitMEX, or ensure 2-factor authentication is enabled.
Binance CEO, Changpeng Zhao, also reached out to potential victims who might also have a Binance account linked to the same email. He urged people to use unique email addresses for each crypto exchange account to prevent widespread issues.
