South Korea’s SK Telecom begins SIM card replacement following data breach

SEOUL: South Korea’s largest carrier SK Telecom started on Monday to replace mobile SIM chips for its 23 million users following a data breach, prompting alarmed customers to form long queues for the replacements.

SK Telecom announced earlier this month that it had fallen victim to a hacking incident involving malicious code, through which customers’ personal information was compromised.

It prompted a company apology and the government to order the review of the country’s overall data protection system.
