Ransomware Cyber-Attack A Wake-Up Call

The virus, which took control of users' files, spread to 100 countries, including Spain, France and Russia.Investigators are working to track down those responsible for the ransomware uknown as Wanna Decryptor or WannaCry.

Some ransomware does also sometimes targets backup files, though. This means that it gets into your computer and looks for other computers to try and spread itself as far and wide as possible.

The Computer Emergency Response Team of India (CERT-In) has issued a red alert about the ransomeware.

It should be noted that Microsoft makes it clear that when an older operating system reaches end-of-life, it no longer receives free support.

Many companies are of course reluctant to deploy patches without extensive testing, something which Microsoft understood, but Smith noted that Microsoft used "robust testing and analytics to enable rapid updates into IT infrastructure".

It added that WannaCry was targeting common file extensions such as ppt, doc, and tiff, along with media files such as MP4 and MKV files. Next is to educate the workforce about what to click and what to ignore when it comes to suspicious links.

As the massive ransomware attack spread like wildfire across hundreds of countries over the weekend, experts estimated that the ransomware, dubbed WannaCrypt or WannaCry, infected over 100,000 computers in almost 150 countries.

Currently, there is no permanent fix that could end the wrath of this ransomware, but here are a few pointers that could help you in protecting your Windows PC if it has not been attacked yet.

Five hospitalised in United States after eating nacho cheese from a petrol station
Nine people have been hospitalized after eating nacho cheese from a Sacramento gas station, California officials said. She picked up a bag of Doritos chips and drizzled them with nacho-cheese sauce, said her partner, Ricky Torres.

In one instance, the cyber attack prevented people from receiving hospital care.

A message will appear onscreen with a ransom demand, countdown timer and bitcoin wallet to pay funds into. There is no other way to get out of it. For those systems that can not be updated, he suggested blocking SMB traffic on ports 139 and/or 445.

It told customers to update their computers as millions could be affected by the WannaCry virus today. That data should be stored offline on a hard disk.

The company said the U.S. government kept information about Windows vulnerabilities which later got stolen and used to spread the WannaCry ransomware which has swept the world this weekend.

Experts say victims of WannaCry initially received an email asking them to download an attachment.

Two researchers in their 20's had halted the ransomeware attack on Saturday after discovering and activating the software's "kill switch". India also has the most number of pirated software users.

And now, the group named Shadow Brokers, that had leaked the tools from the United States national security agency's stockpile of cyber weapons, which were used by hackers for the recent attacks has said in a blog that it would be releasing hacking tools every month.
