SK Telecom vows to take full responsibility for damage from recent data leak

Posted on April 27, 2025 by Dissent

Oh Seok-min reports on how SK Telecom is attempting to reassure panicked customers following a significant data breach:

SK Telecom Co., South Korea’s leading mobile carrier, vowed Sunday to take full responsibility for any damage to customers caused by a recent network hacking incident involving the potential leak of subscriber information.

Earlier this month, the carrier detected signs of a massive leak of customers’ universal subscriber identity module (USIM) data due to a cyberattack and offered the free replacement of the USIMs of all of its 23 million users.

“You can prevent hacking damage by subscribing to the USIM protection service. Please trust us and sign up,” the company said in a release. “If any damage occurs, SK Telecom will take full responsibility.”

As of 6 p.m., 5.54 million people had subscribed to the service, accounting for 24 percent of the carrier’s total subscribers.
