Donga reports that a South Korean defense-industry subcontractor was hacked and that authorities suspect North Korean involvement. The stolen material reportedly involved technical data and operations or maintenance manuals connected to Baekdu and Geumgang reconnaissance aircraft, which are core South Korean airborne intelligence assets. The incident is significant for CTI teams because it reflects strategic collection against defense supply chains and could help North Korea understand, evade, or improve capabilities related to South Korean reconnaissance systems.
