June 26 (Asia Today) -- More than 4 in 10 South Korean employees who participated in a government cybersecurity exercise opened simulated phishing emails, but companies that had conducted repeated training recorded significantly better results, officials said Friday.

The Ministry of Science and ICT and the Korea Internet & Security Agency announced the findings at a review meeting at the Post Tower in central Seoul.

A total of 630 companies and 255,460 employees participated in the government's cybersecurity crisis response exercise for the first half of 2026.

The government conducts the exercise twice a year to improve security awareness and strengthen companies' ability to respond to cyberattacks.
