About this actor

Korea Atomic Energy Research Institute disclosed June 2021 that 13 unauthorised accesses had occurred via a VPN vulnerability; South Korean parliament members and AhnLab attributed the activity to DPRK-aligned Kimsuky. No domestic insider charged; investigation focused on credential misuse.
