In the cyberattack, which took place last month, the adversary exploited a vulnerability in a VPN system used within the research institute’s environment, KAERI said Friday. In response to the attack, the VPN was updated and the attackers’ IP address blocked.
“Currently, the Atomic Energy Research Institute is investigating the subject of the hacking and the amount of damage,” the institute also said.
South Korean news outlet Sisa Journal broke the news about the hack, but KAERI initially denied the claims. On Friday, the research institute apologized for that.
