The South Korean National Election Commission reported a cyber attack on Wednesday as the country voted to elect a new parliament.
A denial of service attack (DDoS) hit the website of the South Korean electoral body for three minutes at 2.22 p.m. (local time) on Wednesday, Yonhap news agency reported.
The cyber attack targeted the search engine that helps voters find designated polling stations, the commission said in a statement.
However, all online services resumed after a few minutes and no damage was reported.
The election watchdog has alleged that the incident was an intentional act and has asked police to investigate it.
In previous cyber attacks on public and private organisations in South Korea, the government has blamed hackers from North Korea, although in this case, no fingers have so far been pointed at the neighbouring country.
