Yonhap reported that classified information on South Korean Defense Intelligence Command overseas operatives, including identities and personal details, was leaked through a civilian employee's personal laptop. The leaked material reportedly included information on both overt and covert personnel, and investigators identified indications that some information may have reached North Korea. Military counterintelligence authorities were investigating whether the employee's hacking claim was credible, how internal-network data moved to a personal device, and whether negligence, intentional exposure, or accomplices were involved.
