Police confirm 5 more cyberattacks in Japan

Amid the current series of global cyberattacks, police say they have confirmed 5 more cases in Japan.

This brings to 7 the total number of cases confirmed in the country since the global attacks were first reported on Friday.

The National Police Agency says the new cases were confirmed as of 5 PM on Monday.

Investigators say the targets were a company in Gunma Prefecture, north of Tokyo, and 4 individuals in Tokyo, Shiga, Okayama and Fukuoka prefectures.

In each case, ransomware encrypted the computers' data and locked the users out of their systems. Messages then appeared demanding payment in bitcoins before access would be restored.

The agency says the attacks did not affect the company's operation or cause any financial loss. It is investigating to see if any other damage was caused.

The agency reported on Sunday that 2 cases had been confirmed in Japan. The targets were a general hospital in Ibaraki Prefecture, northeast of Tokyo, and an individual in Kagawa Prefecture, western Japan.
