A global cyber outage is affecting airlines, banks, newsrooms and even the London Stock Exchange.
Organisations in the UK, US, Australia and Singapore have been impacted by the outage which seems to be linked to Microsoft Windows and cybersecurity firm Cloudstrike.
Flights have been grounded in the US, airports in Europe, Australia and Singapore have been impacted while Sky News has been unable to broadcast since early this morning.
Business journalist Emmet Oliver says it doesn't appear to be a cyber-hacking, but a software issue:
"It's a software update that or certainly seems to be a software update to a Microsoft Windows operating system. They have a security framework that sits on that called CrowdStrike. It did an update yesterday evening, innocent enough, apparently, and it seems to have gone wrong, and seems to have sent down all these Windows based systems. If you're on Windows, on a Windows operating system, you're more vulnerable to this."
Cyber security expert Ronan Murphy from Smartech247 told the Neil Prendeville Show that says the issue could take several days to fix:
"You can't actually roll this back. That's what it looks like. Meaning that if somebody turns on their computer this morning and they get this blue screen of death, it looks like it actually has to be manually fixed on each device, as opposed to being able to, you know, just push our software update to fix it. And that means it's going to be pretty labour intensive.
