World braces for more cyber attacks as week begins

20 Mai 2017

About two-thirds of the internet-connected computers sidelined by last week's unprecedented ransomware attack were running outdated versions of Microsoft's Windows 7 operating system at the time of infection, according to a new report.

Since Friday, more than 200,000 victims in around 150 countries have been infected by the ransomware which originated in the United Kingdom and Spain on Friday before spreading globally.

Wainwright said he was concerned that the numbers of those affected would continue to rise when people returned to work on Monday morning.

What is Wanna Decryptor Ransomware? The malware can directly decrypt system files using a unique decryption key. Microsoft released Windows 8 in 2012 and Windows 10 in 2015.

Pictures posted on social media showed screens of NHS computers with images demanding payment of 300 USA dollars worth of the online currency Bitcoin, threatening to delete files within seven days.

The ransomware was initially found spreading through attachments in email phishing campaigns.

The virus, which took control of users' files, spread to 100 countries, including Spain, France and Russian Federation.

Greyfriars Practice manager Karen Young told The Standard they had still had no computers. However, if your devices have been infected by WannaCry - the malware that has affected the NHS' computer system - the ransomware will lock your entire PC. (Bitcoin in a type of digital currency widely used online.) Victims have only hours to pay the ransom, which rises to $600 before the files are destroyed.

The safest way to protect yourself is to avoid clicking links from unknown sources.

The phenomenon of companies failing to update their systems has been a persistent security problem for years.

"In particular, making sure that our data is properly backed up and making sure that we are using the software patches, the anti-virus patches, that are sent out regularly by manufacturers".

Microsoft itself has issued an update of their software to plug the holes but there are lots of computers out there that are not updated for one reason or the other.

Britain's National Crime Agency (NCA) also said it had seen no evidence of a "second spike in WannaCry ransomware attacks" by midday, but warned that another attack could still happen.
