It is said that 2.3TB of data from Japan’s Public Security Intelligence Agency (PSIA) was leaked, but is that true?

Japan has several spy organizations. This time, the story is about the PSIA.

By the way, the PSIA is a different organization from the Public Security Police and the National Public Safety Commission. The PSIA is part of the Ministry of Justice and carries out spy activities. The Public Security Police is part of the National Police Agency and not only does spy work but also has the power to arrest people. The National Public Safety Commission belongs to the Cabinet Office and supervises the National Police Agency.

In Japanese, all three have “public security” in their names, but they are different organizations.

A hacker group called Kirov Elite Group wrote on the dark web that they had hacked a total of 2.3TB of data from the PSIA, including information on staff, top officials, board members, and vehicles. There was 2.3TB of data there, and anyone could download it for free.

This information was also spread on Chinese security websites, blogs, and social media. That was on September 7, 2025.

In conclusion, the data was fake.
