Ransomware cyber-attack a wake-up call, Microsoft warns

A cyber-attack that has hit 150 countries since Friday should be treated by governments around the world as a "wake-up call", Microsoft says.

The computing giant said software vulnerabilities hoarded by governments had caused "widespread damage".

The latest virus exploits a flaw in a version of Microsoft Windows first identified by US intelligence.

There are fears of further "ransomware" attacks as people return to work on Monday.

Many firms have had experts working over the weekend to prevent new infections. The virus took control of users' files and demanded $300 (£230) payments to restore access.
