Protecting Windows-Based Computers From WannaCry Ransomware

Protecting Windows-Based Computers From WannaCry Ransomware

"The numbers are still going up", Wainwright said.

So far there has been no progress reported in efforts to determine who launched the plot. "For those systems that were updated and patched, they were not vulnerable to this particular attack".

Microsoft responded to the WannaCrypt (WannaCry) ransomware attack that hit computer systems around the world Friday by emphasizing the need for taking precautions to protect against attack and urging governments to stop hoarding exploits for security vulnerabilities. And the hackers warned that they would delete all files on infected systems if no payment was received within seven days.

French carmaker Renault said its plant in the northern town of Douai would not reopen on Monday as it dealt with the cyber-attack.

"We should take from this recent attack a renewed determination for more urgent collective action", he said.

In this case, the domain turned out to be a "kill switch"-on any system that made contact with the URL, the virus shut itself down".

The "kill" function had not been activated by whoever unleashed the ransomware, and the researcher found that the secret URL had not been registered to anyone by global internet administrators.

"The U.S.is still the biggest purchaser, driven by the regulations and the legal environment, but we see a lot of buyers in the United Kingdom and a huge demand increase in Continental Europe, and there's been a spike in demand in Asia", he said.

The business interruption and extortion coverage options in cyber policies are increasingly being taken up by policyholders as the incidence of ransomware increase, said Brian J. Dusek, an attorney at McCullough Campbell & Lane L.L.P.in Chicago who specializes in cyber risk and professional liability coverage.

The "WannaCry" global attack affected only computers running on Microsoft Windows operating system.

Multiple leaks were posted, including one on April 14 of this year that contained an exploit (flawed computer code that can be used to craft cyberweapons) called EternalBlue.

"Install the official patch from Microsoft that closes the vulnerability used in the attack.

But what we do know is the malware attacked the vulnerability in Microsoft Windows that Microsoft had released a patch to fix several months ago", Burley, a professor of human and organizational learning at George Washington University told Fox News.

Sumon Ahmed Sabir, Chief Technology Officer of Fiber-at-Home, said that some personal computers too have been infected by ransomware. This will make it much easier to spot potentially malicious files.

With WanaCryptor and MS17-010 both "unleashed into the wild", F-Secure said the current problem seems to have combined and magnified the worst of the dangers those programs represent.

He also compared both WikiLeaks' release of CIA hacking tools in March and the stealing of a Microsoft Windows vulnerability from the National Security Agency last month to the theft of weapons from the USA military.

WannaCry is a weaponized exploit, part of a cyber-espionage toolkit that was allegedly stolen from the U.S.

None of the firms targeted indicated whether they had paid or would pay the hackers ransom.
