Park Won-soon
The DDoS attacks during the October 2011 South Korean by-election were allegedly two separate distributed denial-of-service (DDoS) attacks that occurred on October 26, 2011. The attacks, which took place during the October 2011 Seoul mayoral by-election, targeted the websites of the National Election Commission (NEC) and then-mayoral candidate Park Won-soon. Investigators assert that the attacks were carried out in hopes of suppressing young voters, to the benefit of the Grand National Party. An aide of Grand National Party legislator Choi Gu-sik was found responsible for the attacks.
