The Japan Aerospace Exploration Agency (JAXA) discovered the malware Jan. 6 on a terminal used by one of its employees. A trace showed that the computer virus had gathered information from the machine, officials said.
JAXA still isn't sure how the virus got on the computer, or who put it there.
"Information stored in the computer as well as system information that is accessible by the employee have been leaking outside," JAXA said in a statement today. "We are now confirming the leaked information and investigating the cause."
