In 2020, the number of detected Distributed Denial-of-Service (DDoS) attacks and responses to those attacks by South Korea's Internet and Security Agency totaled about 247 cases, down from about 387 the previous year. Following large-scale cyberattacks on South Korea in 2009, which included DDoS attacks on websites of the Blue House and major government agencies, South Korea established a "DDoS shelter" to mitigate DDoS attacks.
