Major cyber attack could come on Monday, experts warn

The identity of the Shadow Brokers is not known, though many security researchers say they believe they are in Russian Federation, which is a major source of ransomware and was one of the countries hit first and hardest by WannaCry.

Investigators are working to track down those responsible for the ransomware used on Friday, known as Wanna Decryptor or WannaCry.

On Sunday he warned hackers could upgrade the virus to remove the "kill switch" that helped to stop it.

In a major cyber attack, almost hundred countries, including India, were hit which experts said was carried out with the help of "cyber weapons" stolen from the US National Security Agency. Meanwhile, the MalwareTech tracker detected over 100,000 infected systems over the past 2 days.

A number of hospitals in England and Scotland were forced to cancel procedures after dozens of NHS systems were brought down in Friday's attack.

Security researchers with Kaspersky Lab have recorded more than 45,000 attacks in 99 countries, including the UK, Russia, Ukraine, India, China, Italy, and Egypt.

Around a fifth of trusts were hit, with six still affected 24 hours later, amid concerns networks were left vulnerable because they were still using outdated Windows XP software.

"Staff working on computers are both the weakest link when it comes to cyber attacks and the last line of defence".

The National Cyber Security Centre said they are continuing to actively monitor the situation, and to engage with entities across Government and the private sector in terms of managing the response to this malware.

The attack, boiling down to a computer virus that makes users' computers useless unless a payment is made to those who hacked their system, has prompt wide alarm around the globe.

"The potential for any organisation or individual to fall victim to increasingly clever cyber criminals gets bigger every day, corresponding exactly with the dependence on computers".

"I don't think it's to do with that preparedness".

Security experts said that they were not sure how many victims would pay the ransoms, or if access to computers was being restored after such payments.

In March, Microsoft patched this particular vulnerability on which the exploit behind these attacks are based, but several organizations around the world did not deploy the security update: Microsoft Security Bulletin MS17-010. This is not the first time she has looked lost in cyberspace.

"The problem is the larger organizations are still running on old, no longer supported operating systems", said Lawrence Abrams, a New York-based blogger who runs

"The public has a right to know exactly what the Government will do to ensure that such an attack is never repeated again", he wrote.

Cyber extortionists tricked victims into opening malicious malware attachments to spam emails that seemed to contain invoices, job offers, security warnings and other seemingly legitimate files.

Just one day before the attack Dr Krishna Chinthapalli, a registrar in London, warned in a British Medical Journal article that some hospitals "will nearly certainly be shut down by ransomware this year".

Germany's national railway said Saturday departure and arrival display screens at its train stations were affected, but there was no impact on actual train services.

The assault, described as the biggest-ever cyber ransom attack, struck state agencies and major companies around the world - from Russian banks and British hospitals to FedEx and European auto factories.
