November 30, 2012 (JST)

Japan Aerospace Exploration Agency (JAXA)

On November 28, the Japan Aerospace Exploration Agency (JAXA) found that one of JAXA's personal computers used by its employee has been infected by a virus, and the following information might have leaked.
We are currently investigating the cause of the infection as well as specifying what information may have been leaked.

  1. Possibly leaked information
    • Specification and operation related information of the Epsilon Launch Vehicle
    • Specification and operation related information of the M-V, H-IIA, and H-IIB Launch Vehicles that is relevant to the development of the Epsilon Launch Vehicle
  2. Situation clarified to date
    On Nov. 21, a virus was detected in the personal computer, then it was immediately detached from the network to check the status. As a result, virus infection was found on the computer on Nov. 26. Through further investigation, we confirmed a trace that some information was collected via the virus and also a record of a connection with some outside source. We are now examining if the information leak really took place and checking the impact of the virus infection.
    In addition, we are also making sure if any other JAXA computers have ever been infected by a virus or not.
  3. Countermeasures for the future
    We would like to express our sincere apology for causing such a situation. As we take this incident very seriously, we would like to address the following countermeasures while further strengthening our information security in order not to let this happen again.
    • To clarify and deal with contents of possibly leaked information
    • To investigate the cause of infection and take countermeasures for preventing a recurrence.
