Frenchmen claim cure for WannaCry-infected computers
By contrast, the United States accounts for 7 per cent of WannaCry infections while Britain, France and Germany each represent just 2 per cent of worldwide attacks, Kryptos said. “In other words, Microsoft had fixes ready to go for its legacy systems in mid-February but only released them to the public last Friday after the world was engulfed in WannaCrypt”.
Microsoft is now trying to convince users to move over to Windows 10, as numerous devices running on older software still remain vulnerable to attacks. The top security features must be added in all the versions of Windows. Microsoft appears to have sent the patch to its custom support customers earlier this year.
Liran Eshel, chief executive of cloud storage provider CTERA Networks, said: “The attack shows how sophisticated ransomware has become, forcing even unaffected organisations to rethink strategies”.
French security researcher Adrien Guinet has figured out a way to decrypt files locked by the infamous WannaCry ransomware.
As security researcher Kevin Beaumont pointed out, the NSA’s Eternal Blue exploit that WannaCry attackers used to spread the ransomware once inside a network can not be used to infect Windows XP machines on that network.
A week ago, hackers were able to infect more than 200,000 computers across the globe, and encrypt data stored on the affected machines. The result: “Users unlikely to get files restored”, the company’s Security Response team tweeted.
The tool may be helpful for XP users infected with WannaCry, but a similar tool for Windows 7 is likely to have a bigger impact at sites such as the UK NHS hospitals that were hit hard by the recent ransomware attack.
Once installed, WannaCry locks the files on a computer and asks its victims to pay approximately $300 by Bitcoin within a few hours.
WannaCry ransomware locks up files, but XP users may now have a way of recovering them but only if they haven’t restarted their machine.
The Verizon 2017 Data Breach Investigations Report, the most comprehensive annual survey of security breakdowns, found that it takes three months before at least half of organisations install major new software security patches.
“We haven’t seen many organisations fall over and that’s because they did some of the security basics”, he said.
