South Korean police said they have arrested a hacker for staging cyber attacks similar to those that crippled domestic and US websites this week.
The 39-year-old identified only as Choi is accused of paralysing the homepage of the government Game Rating Board by using a distributed denial-of-service (DDoS) method.
Choi was an agent for software developers seeking approval from the board for new games. Because he failed to finish one job on time, he crashed the site to create an excuse for his tardiness. Choi is accused of buying a hacking programme from an ethnic Korean in China.
