China reportedly had ‘deep, persistent access’ to Japanese networks for months
Cybersecurity breach in Japan's defense networks by hackers from China.
Key points:
- Hackers from China had "deep, persistent access" to Japanese defense networks.
- The breach was discovered by the National Security Agency in late 2020 and persisted through the end of the Trump administration and early 2021.
- Japan initially declined assistance from US Cyber Command and opted for domestic commercial security firms, but later adopted a more active national security strategy, including the establishment of a new cyber command and the addition of 4,000 cybersecurity personnel.
