Cyber attack continues to cripple computer systems across the world

China and Japan have both fallen victim to the global ‘ransomware’ cyber attack that has created chaos in 150 countries.


Chinese state media say more than 29,000 institutions across the country have been infected, along with hundreds of thousands of devices.

Xinhua News Agency cited the Threat Intelligence Centre of Qihoo 360, a Chinese internet security services company.

It said universities and educational institutions were among the hardest hit, numbering 4,341, or about 15 per cent of internet protocol addresses attacked.

Also affected were railway stations, mail delivery, petrol stations, hospitals, office buildings, shopping malls and government services.

Xinhua says the system used by PetroChina’s petrol stations was attacked, meaning customers could not use their cards to pay. Most stations had recovered.

Japanese companies say they are working to overcome the problems caused by the cyber attack.

The Japan Computer Emergency Response Team Co-ordination Centre said 2,000 computers at 600 companies in Japan had been affected.

Nissan confirmed on Monday some units had been targeted, but that it had responded and there had been no major impact on its business.

Hitachi spokeswoman Yuko Tainiuchi said it was experiencing email delays and file delivery failures and suspected the cyber attack was to blame, even though no ransom was being demanded. Programmes were being installed to fix the problem.

Broadcaster NTV reported 600 companies and 2,000 computers in Japan had been affected.

The Indonesian government urged businesses to update computer security after two hospitals were affected by the cyber attack.

The communication and information ministry said the malware locked patient files on computers at the affected hospitals, both in the capital

Local media reported that patients arriving at Dharmais Cancer Hospital over the weekend were unable to get queue numbers and had to wait several hours while staff worked with paper records.

The ministry has announced measures that organisations can take to counter the attack including a specific update to Microsoft operating systems.

The initial attack, known as ‘WannaCry,’ paralysed computers that run Britain’s hospital network, Germany’s national railway and other companies and government agencies worldwide in what is believed to be the biggest online extortion scheme in history.
