Hanyang Securities reports leak of 31 personal data records
South Korean brokerage Hanyang Securities confirmed 31 personal data records were exposed after unusual access to a work groupware system.
The records included information linked to 15 customers, two employees and 14 other personal data entries.
Exposed details included names, account numbers, contact details and addresses, while three records included resident registration numbers.
The system was Daou Office, also used by Bithumb, which reported a separate breach last month.
It is not known whether the two incidents involved the same attack route or security weakness.
Hanyang Securities blocked outside access and installed an urgent security patch, and says it has notified affected customers.
The company is still investigating how the breach happened and how much data was exposed, as South Korean financial regulators step up security checks.
