Poor security at Japan Pension Service preceded cyber-attack / Most leaked files not protected by passwords

Yomiuri Shimbun reports:

An investigation into the recent unauthorized access of personal information from the Japan Pension Service found that 99 percent of the files accessed were not protected by passwords, sources said.

This contrasts with multiple reports issued since 2013 by all JPS offices nationwide claiming full compliance on password rules. If the files accessed were not protected by passwords, it would suggest that most of these reports were false.
