Japan's space agency has come under cyber attack but the information hackers reached did not include anything important in terms of missile and satellite operations, a spokesman for Japan's Aerospace Research Agency (JAXA) said on Wednesday.

The country's Ministry of Education, Culture, Sports, Science and Technology confirmed Wednesday to the media that one of the network services of the Japan Aerospace Exploration Agency (JAXA) has suffered a hack.

The ministry stressed that the server in question did not contain information about Japan's missile and satellite operations and insisted that the possibility of leaking confidential information was minimal.

"There was a possibility of unauthorized access by exploiting the vulnerability of network equipment," a JAXA spokesperson noted, declining to elaborate on details such as when the cyberattack took place.

The space agency learned of the possibility of unauthorized access after receiving information from an outside organization and conducting an internal investigation, its spokesman said, declining to identify the organization's name.

The ministry and JAXA are still investigating the origin of the attack and how it may have damaged the space agency's systems.

Japanese media reported that the cyberattack took place over the summer, with police learning of the attack and notifying JAXA this fall. The first to report on the incident was the newspaper Yomiuri.
