Computer Virus Infection at JAXA


On January 6, 2012, the Japan Aerospace Exploration Agency (JAXA) found that a
computer terminal used by one of our employees was infected with a computer
virus, and information stored in the computer as well as system information that
is accessible by the employee have been leaking outside.
We are now confirming the leaked information and investigating the cause.


Broadly Risks

1. Possible leaked information
As the computer was used by an employee who is involved in the H-II Transfer
Vehicle (HTV, a cargo transporter to the International Space Station,) the
following information was potentially compromised.

– Stored mail addresses
– Specification and operation information of the HTV
– System log-in information accessed from the computer

2. Currently confirmed background
On August 11, 2011, some anomaly was detected in the said computer, thus it was
detached from the network for checking. As a result, on August 17, we found that
the computer was infected with a virus. The virus was removed, but the computer
has continuously been monitored and investigated since then because it was still
unstable and displayed abnormalities. On January 6, 2012, we found a trace that
a different virus had gathered information from the computer. In addition, it
was also discovered that the computer sent out some information sometime between
July 6 and August 11.
With the above backdrop, passwords for all accessible systems from the computer
have been immediately changed in order to prevent any abuse of possibly leaked
information, and we are currently investigating the scale of damage and the
impact. Also, all other computer terminals are being checked for virus

3. Further steps to take
We sincerely apologize over such trouble, and we will promptly address the
following measures while strengthening our information security in order to
prevent any recurrence, as we gravely regret this incident.

– Specify leaked information and investigate the cause.
– Take measures to prevent a recurrence according to the investigation.
– Call attention and caution the person if his or her personal information is
found to have been leaked.
