WannaCry exploited a known Microsoft vulnerability for which there was a patch on Windows 10, but not for some of the older Windows OSes that companies continue to use.
According to Ryan Kalember, the senior vice president for cybersecurity at Proofpoint, the attack employed the same hacking tools developed by the U.S. National Security Agency (NSA) and leaked to the public by the hacker group Shadow Brokers in April to exploit vulnerabilities in the Microsoft Windows operating system.
"Ransomware generally gets into the system through user interaction", Staats said. Even though there are ways to install the latest updates on updates on Windows which are not genuine, Microsoft is also implementing restrictions every once in a while, so depending on the release, it could be more or less hard to patch a pirated Windows copy.
And when you're considering a new digital device, whether that's a phone, a computer or a smart-home gadget, it's worth looking into just how long the manufacturer promises to support it with software updates (if it makes any promises at all).
One way yo can protect yourself from such an attack is by installing the latest security update and not install any pirated versions.
Can you imagine? Software that could hold a city's sewage system for ransom?
A hacking group known as the "Shadow Brokers" has been blamed for stealing surveillance tools from both the NSA and the Central Intelligence Agency and then leaking them online. Essentially if you're running a Windows OS version lower than Windows 10, you're at a higher risk. "It knows how to exploit vulnerabilities in Windows XP, Windows Vista, Windows 7, Window Server 2008 and earlier versions", he added further. The British government canceled a nationwide NHS support contract with Microsoft after a year, leaving upgrades to local trusts.
Microsoft declined to comment for this story. Also it is best to keep all software updated, run only licensed version of any OS. Around 30,000 of those are located in China, according to the newspaper. You could say an attack of this nature has been coming, particularly when a 2016 study by ISP Beaming, suggested cyber-attacks were already costing British businesses around £34bn. A month later the hackers used that tool to perform their powerful ransomware attack.
Last Friday, the company's British-based 22-year-old data breach research chief, Marcus Hutchins, created a "kill-switch", which security experts have widely hailed as the decisive step in halting the ransomware's rapid spread around the globe. Ordinary computer users need to apply common sense to guard their machines both at home and at work against virus and malware infection.

Researchers from a variety of security firms say they have so far failed to find a way to decrypt files locked up by WannaCry and say chances are low anyone will succeed. Patching is ultimately the best remedy against ransomware attacks like WannaCry, as it targets the root of the vulnerability. As a result, enterprise security is failing despite the billions of dollars spent. "It jumped to $1,000 after that", the report said.
"We have found evidence of much more sophisticated actors leveraging the NSA EternalBlue exploit to infect, install backdoors and exfiltrate user credentials in networks around the world, including the USA, three weeks prior to the WannaCry attack", Barak wrote in a blog post. It also installs a countdown timer on the victim's wallpaper, demanding that the ransom be paid to avoid having private files deleted.
"The same things are causing the same problems". Also, download anti-virus apps only from reputable vendors like Kaspersky Lab, Bitdefender or Malwarebytes, Kamden said.
After the results, Snap shares fell immediately, trading almost $18.19 which is the lowest since it went public. Another factor hurting Snap shares is their perceived lack of ability to differentiate themselves from rivals.
