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
So, in Aug 2011 it already had a "virus" on it, which was removed. And now a new "virus" on the same computer?
Coincidence? I think not.
