Microsoft re-releases security update after cyberattacks

"WannaCrypt" the ransomware malware used in Friday's massive cyber-attack has the ability to spread itself within corporate networks, without user interaction, by exploiting a known vulnerability in Microsoft Windows as per the reports. But many computer systems are not set for automatic updates, and older systems may not even be supported anymore. The BBC reported that more than 200,000 computers were hit.

"This attack provides yet another example of why the stockpiling of vulnerabilities by governments is such a problem", Smith wrote.

Hypponen added that Russian Federation and India were hit particularly hard, largely because Microsoft's Windows XP - one of the operating systems most at risk - was still widely used in the countries.

The first step is being cautious, experts say. The National Cyber Security Center said: "We are aware of cyber incident and we are working with NHS Digital and the National Crime Agency to investigate".

There are several factors in play.

Meanwhile health authorities are racing to upgrade security software amid fears hackers could exploit the same vulnerability with a new virus. "The numbers are going up, I am anxious about how the numbers will continue to grow when people go to work and turn (on) their machines on Monday morning", Europol Director Rob Wainwright told Britain's ITV.MONDAY MORNING RUSH?

At least one strain of the ransomware has proven especially vicious.

Meanwhile in Hong Kong, the ransomware reportedly affected devices belonging to three individuals, who had not installed the latest security updates on their Windows 7 operating system, and were directly connected to the internet.

And while Smith is correct as far as he goes, the fact remains that Microsoft did know about the vulnerability before the attack.

In the world of ransomware, that was "unheard of six months ago", Levy said. ".@NSAGov's choices risked permitting low-skill criminals launch government-scale attacks, and then it happened", Snowden tweeted on Saturday.

NHS Digital, which oversees United Kingdom hospital cybersecurity, said it sent alerts about the problem - and a patch to fix it - to health service staff and IT professionals last month.

"When any technique is shown to be effective, there are nearly always copycats", said Steve Grobman, chief technology officer of McAfee, a security company in Santa Clara, California.

Grafi said his firm has been contacted by companies that are scrambling to avoid potential pitfalls. That program spread much more quickly than expected, soon choking and crashing machines across the internet. All have been about exploits for mainly Windows systems.

That tool was leaked recently by hackers who targeted the NSA.

"We have not yet seen Friday's attack reoccur, there's been no new wave of attacks".

Chen Xiaoqiang, a senior at Guilin University of Electronic Technology, lost his senior-year project when he logged into the school's intranet.

The "WannaCryptor", or "WannaCry", virus affected businesses and people in more than 150 countries. The company said the virus has been localized and "technical work is underway to destroy it and update the antivirus protection".

This backup can save you from significant stress, time and money in the event when your computer becomes infected. The government says that under a previous Labour administration the trusts that run local hospitals were given responsibility to manage their own computer systems.

Smith also called cyberattack protection a "shared responsibility" between companies and customers.

"We have been in touch with Microsoft and others.even they have not got any reports", Indian Computer Emergency Response Team (CERT-In), director general, Sanjay Bahl told PTI. The opposition Labour Party accused the Conservative government of leaving the National Health Service vulnerable. This feature will also be integrated into the various Office apps/programs to facilitate easy access to that data across devices. "We will continue to work with affected (organizations) to confirm this", the agency said.

NHS England said that, as of 3pm on Monday, two hospitals remained on divert following the attack, down from seven on Sunday.

The situation is so bad experts have been saying that governments should use this as a wakeup call.
