The reason for the difference between Coupang’s fine of 1 trillion won and SKT’s fine of 100 billion won.

*This graph was created in August before Coupang exploded, so this Coupang is not listed.

As the Personal Information Protection Act was revised in 2024, specific standards for calculating fines were established. The calculation standard is 3% of sales compared to the previous year, excluding sales that are not related to the information leak of about 23.23 million people.

So, the initial SKT fine estimate was up to 300 billion won.

However, the reason for the reduction was recognized and the final calculation was 134.8 billion won.

Until then, it was the highest fine ever for personal information leakage.

However.

Coupang’s leak size is the highest ever, far exceeding the SKT leak size of 33.7 million cases, and Coupang’s sales last year were KRW 44.47 trillion, so 3% of that amount was set, resulting in an amount of KRW 1.33 trillion.

However, Coupang is still in the process of following up, so if the reason for the reduction is recognized like SKT, the amount actually charged by Coupang is expected to fall further according to follow-up measures, as SKT has reduced the amount calculated by up to 3% by almost half from KRW 300 billion.

And now there are strong words such as that Coupang may be subject to business suspension, and SKT also said that business suspension may be imposed, but as a result, it is not implemented, so I think this is a warning threatening to suspend business if proper follow-up measures are not taken.

summary

1. SKT KRW 134.8 billion is the amount that was recognized as a reason for reduction in the 3% fine of sales related to information leakage compared to the previous year.

2. Coupang’s KRW 1.33 trillion is 3% of the previous year’s sales and may fall further as reasons for reduction have not yet been applied.

Not only Coupang was hit hard, but SKT was tolerated, but the 3% fine was increased for Coupang due to the size of the personal information leak and the difference in sales from the previous year (SKT: KRW 12.77 trillion, Coupang: KRW 44.47 trillion).
