Global cyberattack update

TOKYO (AP) - Global cyber chaos is spreading Monday as companies boot up computers at work following the weekend's worldwide "ransomware" cyberattack.

The extortion scheme has created chaos in 150 countries and could wreak even greater havoc as more malicious variations appear. The initial attack, known as "WannaCry," paralyzed computers running Britain's hospital network, Germany's national railway and scores of other companies and government agencies around the world.

As a loose global network of cybersecurity experts fought the ransomware hackers, in China, state media said more than 29,000 institutions had been infected along with hundreds of thousands of devices.

The Japan Computer Emergency Response Team Coordination Center, a nonprofit providing support for computer attacks, said 2,000 computers at 600 locations in Japan were reported affected so far.
