With organisations in as many as 99 different countries experiencing similar attacks.

The attacks affected phone lines and computers with many having their screens blocked by a programme that demanded money.

A second massive wave of attacks is expected today as staff log back on to work systems.

Some machines may still not be protected from the ransomware called Wannacry that hit last Friday, the National Cyber Security Centre said.

A warning has now been issued, urging businesses and individuals to be vigilant over the coming days and follow protection advice to make sure that they don’t fall victim to similar scams.

Here is all you need to know:

What is ransomware?
Ransomware is a type of Malware that infects computers or mobile devices and allows cyber criminals to hold your files ransom.

The software will lock down the files and then attempt to extort money from you before you are able to access them again.

How can ransomware infect your devices?
Ransomware can infect any device that is able to connect to the internet.

There are a number of ways that the software can infect your device, the most
common is through a link to a malicious website through an email, or through a security vulnerability in a piece of software you use.

What can you do to protect your business?
- Install system and application updates on all devices as soon as they become available.
- Install anti-virus software on all devices and keep it updated.
- Create regular backups of your important files to a device that isn’t left connected to your network as any malware infection could spread to that too.
- The National Cyber Security Centre’s technical guidance includes specific software patches to use that will prevent uninfected computers on your network from becoming infected with the "WannaCry" Ransomware:

What can you do to protect yourself?
- Install system and application updates on all devices as soon as they become available.
- Install anti-virus software on all devices and keep it updated.
- Create regular backups of your important files to a device (such as an external hard drive or memory stick) that isn’t left connected to your computer as any malware infection could spread to that too.
- Only install apps from official app stores, such as Google’s Play Store, or Apple’s App Store as they offer better levels of protection than some 3rd party stores.

Jailbreaking, rooting, or disabling any of the default security features of your device will make it more susceptible to malware infections.

What should you look out for following the ransomware cyber attacks?
It is believed that cyber criminals could use the ransomware attack as part of phishing or smishing campaigns.

Campaigns like this involve fraudsters contacting you using false stories to try to obtain information from you.

People are now being warned to be cautious with any emails received from unknown addresses, especially any unsolicited contact.

The following protection advice has been issued:
An email address can be spoofed. Don’t open attachments or click on the links within any unsolicited emails you receive, and never respond to emails that ask for your personal or financial details.

The sender’s name and number in a text message can be spoofed, so even if the message appears to be from an organisation you know of, you should still exercise caution, particularly if the texts are asking you to click on a link or call a number.

Don’t disclose your personal or financial details during a cold call, and remember that the police and banks will never ring you and ask you to verify your PIN, withdraw your cash, or transfer your money to another "safe" account.
