The record 1 development
Bithumb says a break-in to an internal system exposed 844 customers' personal data
What happened. Korean exchange Bithumb said outsiders got into DaouOffice, its internal mobile work system, without authorisation on 27 October. 6,444 customers were involved; for 5,600 of them the data was encrypted and unreadable, and leaks of personal information were confirmed for 844. Information on 715 employees and partner staff was also affected. Bithumb said the system is separate from its trading platform and customer databases and that it has seen no access to customers' crypto.
Why it matters. South Korea's Financial Services Commission held an emergency meeting on 28 October, began an on-site investigation with the Financial Supervisory Service, and said it will make sure users are fully compensated if they suffer losses. It also said it will raise security requirements for crypto firms, which fall outside the Electronic Financial Transactions Act, to the level of banks.
- The data may include names, phone numbers, email addresses, resident registration numbers, driver's licence numbers, bank account numbers and copies of ID cards, Bithumb said.
- Bithumb reported the incident to the Korea Internet & Security Agency and the Personal Information Protection Commission and said it will support and compensate customers with verified losses.
