Executives at three credit card companies bowed in apology before the South Korean public on Monday after a man hired by a credit ratings firm stole client data from as many as 20 million people, 40 percent of the nation’s population, the New York Times reported.
At a news conference, the executives promised compensation to customers for any financial losses due to the data heist.
Earlier this month, authorities arrested a 39-year-old technician working for Korea Credit Bureau, a ratings firm the credit card companies had hired to improve how they protect client data.
