Cybercriminals have compromised at least 200,000 credit card owners in South Korea, with forged credit cards and fraudulent charges being reported. South Korean police authorities have identified more than 250 cases of fraudulent charges, and expect that number to increase as customers are notified to look for suspicious activity.
The hacker successfully breached a company in South Korea responsible for managing card payment processing terminals, collecting credit card numbers, expiration dates, and loyalty card passwords, according to the Financial Supervisory Service (FSS).
The FSS found credit information from three credit card companies and one bank were leaked, with two of the credit card companies already publicly punished for significant data breaches. Earlier in the year, more than 100 million South Korean credit card and bank accounts were compromised, with bank officials resigning and facing heavy scrutiny from government officials.
