In a bid to minimize the political damage from the latest pension system scandal, Chief Cabinet Secretary Yoshihide Suga on Tuesday admonished the government-affiliated Japan Pension Service and announced that a team will be set up to probe the massive theft of pension data.

The Japan Pension Service, which manages the basic national pension system designed to cover all residents in Japan, including foreigners who pay into the scheme, said Monday that part of its computer system was hacked and personal data on 1.25 million contributors and recipients was stolen.

Despite previous instructions not to open any suspicious email attachments, several JPS workers accessed a virus-infected file sent to their work computers.
