Overview
- The cabinet met on Monday and Prime Minister Takaichi signaled that 'active cyber defense'—measures that can include entering attacker servers to neutralize threats—is a possible option for responding to recent unauthorized accesses.
- Tokyo directed cyber officials to work with allied countries and foreign agencies to identify attackers faster and tasked them with producing an emergency countermeasures package to be completed soon.
- Park24 disclosed that about 1.46 million identity‑verification images from its Times Car service were leaked and offered roughly 3,000 yen per affected record as compensation.
- Victims' lawyers have registered more than 100,000 people and are preparing a collective lawsuit that would seek 50,000 yen for those whose driver's‑license images leaked and 30,000 yen for other affected users.
- The debate over active cyber defense centers on legal authority and cross‑border risks, with affected firms such as GMO pressing for rapid operational measures and officials warning the choice will shape corporate liability, compensation norms, and Japan's cyber posture.
