Biggest Cyberattack in SK Telecom’s History – Likely to Lead to Major Management Changes
- SK Telecom experienced the biggest cyberattack in its history in April which is likely to result in a major shakeup of its management team.
- We estimate SK Telecom could lose 1 million+ mobile service customers. Given its ARPU of 29,355 won per month, this would represent lost annual revenue of nearly 352 billion won.
- This massive cyberattack could cost SK Telecom more than 1 trillion won in a combination of lost revenue and additional commission/advertising necessary to attract new customers.
