Korea Digital Exchange, which operates Flybit, confirmed the leak and posted an apology on the 5th, financial industry sources said on the 12th. An outside attacker gained unauthorized access on the 1st through Daou Tech, the operator of the in-house groupware service used by Korea Digital Exchange.

The leaked data had been included in emails from tax authorities requesting the submission of records. It covered the names, resident registration numbers and contact details of individual customers, as well as the company names and corporate registration numbers of corporate clients. Tax-related documents for some customers were also exposed.

After detecting the breach, Korea Digital Exchange blocked access routes to the affected system and temporarily restricted connections from overseas internet protocol (IP) addresses. The company has asked police to investigate and plans to notify affected customers whose contact details have been confirmed by email and text message.

"We will use this incident as an occasion to review our entire personal data protection system and work with the Korea Internet & Security Agency (KISA) and other relevant agencies to strengthen our security," the company said.
