SK Telecom Faces Significant Consequences Following Data Breach Affecting 23 Million Customers

SK Telecom is facing significant consequences following a data breach that affected its 23 million customers. In April, the company discovered signs of a massive data leak involving USIM (universal subscriber identity module) information due to a cyberattack. SK Telecom has offered free USIM replacements to all its users. In response, the company will be sanctioned for delaying the reporting of the data breach and will be required to waive cancellation fees. Additionally, a criminal investigation has been launched against them.
