A CYBER attack has struck 200,000 people in at least 150 countries, including Australia.
The massive attack on people’s computers is unprecedented* and is mostly sweeping across Europe, but Australia’s Cyber Security Minister Dan Tehan said three Australian businesses had been affected.
The attack is being called ransomware because users are being blocked from access to their computers until they make a payment to the attackers.
The ransomware locks down computers and has been demanding payments of $US300 ($AU406) to $US600 ($AU812) to restore access.
The ransomware attack struck the British National Health Service, along with computer networks of companies and other organisations in dozens of other countries in Europe.
A number of hospitals in England and Scotland were forced to cancel procedures after hospital systems were frozen in the attack, preventing doctors from accessing patient records. Spanish telecommunications giant Telefonica and US delivery service FedEx were among the businesses affected.
US President Donald Trump has ordered an emergency meeting to assess what security threat the global computer ransomware attack poses and to identify who is responsible for the attack.
Cyber Security Minister Dan Tehan said the attack was a good reminder for Australians to ensure they did everything possible to be cyber secure.
“People have to be aware that the impact of ransomware at the moment on the Australian economy* each year we estimate conservatively* at around a billion dollars,” he said.
“We have seen an attack across Europe in particular which has increased the scale of these events.
“We haven’t seen the like of this before but ransomware is occurring here in Australia.”
WHAT TO DO
Special adviser to the Prime Minister on Cyber Security Alastair MacGibbon said the first thing Australians should do when they next log on to their computer is to update their Microsoft software.
They should do this before they open their emails or other programs.
This is because the virus may be spreading via email attachments or trusted websites. If you don’t open or click on to the infected sites then you won’t be impacted, he told the ABC.
He said it was unclear so far how it had started but ransomware generally spread via a few different methods.
Mr MacGibbon said the virus also had wormlike features that looked for other vulnerable* systems once it’s embedded in your computer, which means it can spread to other computers in a network.
He said it was important to regularly update software, and not just when there was a threat.
If you are not sure if your computer’s software is up to date, you can easily check with these steps:
1) Select the Window icon at the bottom left of the screen known as the Start button.
2) In the search box, type “Update” and then in the list of results, click “Windows Update”.
3) Click “Check for updates” and your computer will run a test to find any updates.
4) If it says your device is up to date, you have the latest software available and you should be safe.
unprecedented: never before seen
conservatively: at a minimal estimate
economy: money system
vulnerable : at risk
