South Korea Moves to Tighten Corporate Liability for Data Breaches
On March 9, 2026, South Korea’s government and ruling party proposed a second revision to the Personal Information Protection Act (PIPA), aiming to hold companies more accountable for large-scale data breaches. The amendment seeks to simplify compensation claims for victims by removing the requirement to prove a company’s intent or negligence, shifting the burden of proof onto businesses.
The push for stricter regulations follows a series of high-profile breaches, including a recent incident at e-commerce giant Coupang, where personal data linked to numerous user accounts may have been exposed. The case has heightened scrutiny over corporate data protection practices.
Under the proposed changes, the Personal Information Protection Commission (PIPC) would gain expanded authority, including the power to issue emergency protective orders to contain the spread of compromised data. The amendment also introduces criminal penalties for individuals who knowingly obtain or distribute leaked personal information, closing a legal gap that previously applied only to employees who unlawfully disclosed data.
Officials note that victims often face challenges in gathering evidence to support claims, as companies frequently withhold details on breach causes or resulting damages. The reform aims to streamline the process for affected individuals to seek redress while increasing deterrence against lax security practices.
