Why it matters

Three South Korean financial firms, including Bithumb, reported data breaches, and Yonhap said Daishin Securities disclosed about 38,000 customer records were leaked. Emergency measures were taken, but the reporting does not say how the breach happened or whether the other two firms had the same scale of loss. The immediate issue is data-security risk for customers and possible reputational damage for the firms.
