MICROSOFT has warned of a “wake-up call” as the global cyber attack, which hit computers on Friday, could make a return today with millions across the world thought to be vulnerable. Friday’s shocking cyber attack which brought the NHS to its knees is thought to have hit 150 countries across the globe.
The attack was slowed over the weekend but experts are warning the terrifying ransomware virus could make a return today.
The latest virus exploits a flaw in Microsoft Windows and was first identified by US intelligence.
Microsoft is now warning every user to update to the latest version of the popular software.
A statement from Microsoft president and chief legal officer Brad Smith said: “As cybercriminals become more sophisticated, there is simply no way for customers to protect themselves against threats unless they update their systems.”
Along with telling customers to keep up to date with their software the Microsoft boss has also criticised governments for the way they store up information about security flaws in computer systems.
Mr Smith added: “We have seen vulnerabilities stored by the CIA show up on WikiLeaks, and now this vulnerability stolen from the NSA has affected customers around the world,
“An equivalent scenario with conventional weapons would be the US military having some of its Tomahawk missiles stolen.”
“The governments of the world should treat this attack as a wake-up call.”
Microsoft said it had released a Windows security update in March to tackle the problem involved in the latest attack, but many users were yet to run it.
Europol’s chief has also warned the threat from the cyber attack which took down international services “will continue to grow” when people return to work on Monday.
