PANews reported on June 7th that, according to Yonhap News Agency, South Korea's five major virtual asset trading platforms (Upbit, Bithumb, Coinone, Korbit, and Gopax) experienced a total of 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 incidents, Bithumb 14 incidents, Gopax 8 incidents, Coinone 6 incidents, and Korbit 3 incidents. 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's worth noting that the standards for compiling incident reports, as well as the scale and form of compensation, vary among exchanges. For example, Gopax includes errors in viewing asset lists as system failures, while Bithumb only counts instances where customers experience difficulties using core services for more than 10 minutes as system failures. Furthermore, Bithumb offered free vouchers to some applicants who suffered losses due to system failures, instead of cash compensation. 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.
