Preventing WannaCrypt as simple as running your updates, says Daniel Winson

One of the Riverina’s leading computer security experts says the newest global cyber attack could have been avoided if people simply updated their computers.

A new form of ransomware called WannaCrypt - where files are encrypted until a ransom is paid - crippled thousands of computers and locked up essential services including hospitals in Britain.

Cyber-security specialist Daniel Winson said it exploited a bug in Windows systems that had been known about since March. Even worse for those infected, Microsoft had put out a patch to solve the problems weeks ago.

It’s not just a problem for Windows users either, Mr Winson said, with Apple computers attracting more attention from cyber criminals. He said people should regularly update their computer and keep backups.
