Australian crypto exchange BTC Markets yesterday sent a mass email to its users, which has affected their privacy.
The exchange accidentally put users' names and email addresses in the "To" field of the email. The incident has affected all 270,000 users of BTC Markets, said CEO Caroline Bowler.
BTC Markets said its trading platform remains unaffected by the email issue. "Our external communication process has no interaction with our internal system and no password data was exposed."
The exchange went on to say that it will report the issue to the Office of Australian Information Commissioner to comply with data breach reporting requirements, conduct an internal review, and put additional data security measures.
In the meanwhile, BTC Markets has advised all users to enable two-factor authentication (2FA) to protect themselves from any potential cyber-attacks.
BTC Markets is not the first crypto exchange for having suffered this kind of data breach. Last year, BitMEX accidentally leaked the email addresses of the majority of its users. In June, crypto hardware wallet provider Ledger witnessed a data breach, which exposed approximately 1 million email addresses.
