Member PCs' ASDF, GSDF data also leaked on Winny

Ground Self-Defense Force and Air Self-Defense Force data stored on privately owned computers have leaked onto the Internet via peer-to-peer file-sharing software Winny, following a similar case at the Maritime Self-Defense Force last week, Defense Agency sources said Thursday.

But no confidential information was among the leaked GSDF and ASDF data, the sources said.

Investigations show the GSDF files included members' address lists and drill plans and those from the ASDF included a mock air base construction plan to be used for training.

The computers were apparently infected with a virus that causes information disclosure from an infected machine using the file-sharing software Winny, the sources said.

The GSDF, ASDF and MSDF are currently checking to see if there have been more leaks, the sources said.

Last Friday, the Defense Agency instructed all Self-Defense Forces members to delete all peer-to-peer file-sharing software and work-related confidential data stored on private computers, in order to prevent leaks.
