WannaCry ransomware: 5 things you dint know about

Ransomware

Vu Ngoc Son, deputy head of the anti-malware department of Bkav Corporation, the largest internet security firm in Vietnam, said that the WannaCry ransomware's behaviour is "not new", but he believes that the use of this ransomware will not really ease up as "it can directly earn large profits for hackers". Those include a known and highly unsafe security hole in Microsoft Windows, tardy users who didn't apply Microsoft's March software fix, and malware created to spread quickly once inside university, business and government networks.

They advised those whose networks have been effectively shut down by the ransomware attack not to make the payment demanded - the equivalent of $300, paid in the digital currency bitcoin, delivered to a likely untraceable destination that consists merely of a lengthy string of letters and numbers. In what it said was a "highly unusual" step, Microsoft also agreed to provide the patch for older versions of Windows, including Windows XP and Windows Server 2003.

Corporate world was back on its feet across the globe after more than 2 lakh computers were affected by the virus and the follow-up attack did not materialise as feared, said cyber security experts. WannaCrypt was part of a stockpile of exploits stolen from the NSA earlier this year. Fernandes also elaborates on how one can take cognizance of such occurrences saying: "If you receive e-mail that tells you to open links or visit a page and you do not know the user sending you the e-mail then probably you should trash the email as it is one of the safest ways to avoid an attack".

How should businesses respond to ransomware attacks?

WannaCry ransomware which affected operations at the United States health care system and French auto maker Renault, appears to have had less impact on corporate India's operations.

Second, use state-of-the-art tools to protect the network against known and unknown malware and attacks. Kaspersky Lab says that the majority of affected systems were in Russian Federation. When this happens, you can't get to the data unless you pay a ransom. There is no reason why our government's best security experts should not be able to design a network that would prevent this type of theft.

Russia says latest US Syria strike hit civilians, was unacceptable: Agencies
The airstrike targeted the Syrian regime forces after they breached a "de-confliction zone", according to CNN . It was the first such close confrontation between U.S. forces and fighters backing President Bashar Assad.


Spanish firm Telefonica, French automaker Renault, the US -based delivery service FedEx and the German railway Deutsche Bahn were among those affected.

Britain's National Health Services first sounded the ransomware alarm Friday. Still, beyond the piracy issue, we will no doubt hear for weeks about WannaCry infections because some organizations will be slow to install the patches.

But per Microsoft's point, things aren't going according to plan recently, and our nation's secret keepers have been having a lot of trouble keeping their computer weapons away from the likes of the Shadow Brokers and Wikileaks.

Windows XP is so old, however, that Microsoft stopped updating it several years ago.

"This attack provides yet another example of why the stockpiling of vulnerabilities by governments is such a problem", Microsoft President and Chief Legal Officer Brad Smith said in a blog post on Sunday, comparing the recent leaks of NSA and Central Intelligence Agency hacking tools to, in the real world, the theft of cruise missiles.

Microsoft chief legal officer Brad Smith blamed the NSA's practice of developing hacking methods to use against the US Government's enemies for leaving gaping vulnerabilities. "We need governments to consider the damage to civilians that comes from hoarding these vulnerabilities and the use of these exploits".
