SK Telecom data breach fine (2025)
South Korea's largest mobile carrier suffered a breach and drew an $88 million penalty, then the biggest privacy fine in the country. Regulators cited weak safeguards over subscriber data.
The fine set the prior national ceiling for privacy penalties and pushed carriers to harden systems.
It established that Korean regulators would scale fines to the size of the data holder, setting up an even larger Coupang penalty.
Coupang's fine is more than four times the SK Telecom mark, showing how fast Korea's privacy penalties are climbing.
