South Korea's five major virtual asset platforms experienced 57 hacking incidents and system failures over six years, with total compensation reaching 7 billion won.

According to Yonhap News Agency, South Korea's five major virtual asset trading platforms (Upbit, Bithumb, Coinone, Korbit, and Gopax) experienced 57 hacker attacks and system failures over the past six years (2020 to April 2026), with total compensation amounting to approximately 7 billion won (about US$5.1 million). By exchange, the number of incidents was as follows: Upbit 26, Bithumb 14, Gopax 8, Coinone 6, and Korbit 3. Specifically, Bithumb received approximately 2.5 billion won (about US$1.8 million) in compensation for a BTC mis-sending incident in February of this year; Upbit received approximately 790 million won (about US$570,000) in compensation for a hacker attack in November 2025, and approximately 3.2 billion won (about US$2.3 million) in compensation for a system failure on December 3, 2024. It is worth noting that the standards for compiling incident reports and the scale and form of compensation varied among the exchanges. For example, Gopax counted errors occurring when viewing asset lists as system failures, while Bithumb only counted instances where customers experienced difficulties using core services for more than 10 minutes as system failures. Furthermore, Bithumb offered free vouchers instead of cash compensation to some applicants who suffered losses due to system failures. The compensation amounts for system failures were: Upbit approximately 3.21 billion KRW, Bithumb approximately 3.2 billion KRW, and Coinone approximately 49 million KRW. Korbit and Gopax did not offer any compensation.
