Biggest ransomware attack ever seen.Everything you should need to know about wannacry ransomware attack.

I think in the modern days "data is life" It hurts😔 when someone stolen your own data and ask money for that.
Now I am going to give you all the information about wannacry ransomware that what exactly it do?how can you protect yourself?what can you do if the computer is infected?so that you can protect your precious data of yours and your loved ones.

Now come to the point what is ransomware? and why it is so called wannacry? So this is a malware, a type of trojon virus created to block access to computer system until a sum of money is paid.This ransomware is called as wannacry because it is created by a hackers group known as wannacry.

In this wannacry ransomware they demand the victims to pay 300 dollars in Bitcoins. If the victim doesn't pay till 3 days the amount doubles to 600 dollars and ultimately after 7 days without any payment they deleted all the files and data😤.Now coming to a interesting question why they ask money in Bitcoins so as you know this is a digital currency popular among cyber criminals because it has no central authority, no rules and regulations and practically impossible to trace.

Remember that paying ransom doesn't guarantee that it will remove ransomware from your computer. Fulfillng the demand of hackers only give them funds to create and spread more and more ransomware program.


This is the biggest ransomware attack that we have ever seen occurs on Friday in may 12th.It infected 230,000 computers in 150 countries. European countries were hit the hardest. Government agencies like UK's national health service and telecom providers like Spains telefonica were infected. In India wannacry attack computers including computers of government agencies like Andhra Pradesh police department.


IS THE ATTACK OVER?:-- NO Unfortunately the spread doesn't actually stopped but instead slowed.On Saturday a security researcher named Marcus Hutchins slowed the spread of this virus by registering the domain name hidden within the virus code.


✓THINGS YOU SHOULD DO TO PROTECT YOURSELF FROM THIS RANSOMWARE👍

1) Regardless of which OS, you run install all available security updates and patches immediately.

2) Windows users with computers that run windows XP, windows 8, or windows server 2003 should immediately install security updates and patches released on Friday by Microsoft.

3) Never click on a link by SMS, WhatsApp, Gmail, Facebook, and other untrusted websites and applications.

4) Keep your file backed up regularly and periodically in more than one secure place.

5) Don't use torrent for some days.

6) Don't download songs, softwares, movies, etc. from pirated websites and apps.

7) Mobile phones are affected by these virus or not is not confirmed either there is no such case of it but we have to take safety majors in mobile phones also.

8) An antivirus would work but it's not the best option. wannacry uses so called ETERNALBLUE vulnerability inside windows code. The best way to protect yourself is to install the latest update that fixes the ETERNALBLUE vulnerability or using anti-malware program especially made to protect against sophisticated malwares like ransomware in mind.

9) Don't use filetypes that are targeted and encrypted by wannacry especially .exe file.

10) If your computer is hijacked or attacked immediately shut down the system and seek the help of computer professionals or IP experts. Don't give in.

Water is colourless.why? explained!💧

We see water in different forms and colours.Sometimes it is coloured because of the colour of particles present in it.e.g. bacteria,blue algae,fungi etc.But water is actually a faint blue colour (pure water).The blue colour becomes more clear and enhanced when we look down or through a large volume of water while relatively small quantities of the water appears to be colourless.Example of large volume of water is ocean which is blue when seen from above it.Now some says that blue colour comes from the reflection of the sky.This is the common misconception.This can be explained by the fact that ocean remains blue in cloudy days.When sky is full of white clouds.Now we come to the point that why water is colourless.Reason is given below.


1) We already know that white colour is made up of several colours. Now any matter is made up of little particles (atoms & molecules).When light falls on these particles.Some colours gets absorbed and some gets reflected and that reflected colour when reaches our eyes we see colour in them for example-When we look at an orange🍊 all colour from light except orange colour get absorbed and when that orange colour is reflected reaches our eyes we see orange looks orange in colour😁😂.
similar is the case of water only difference is that it reflect all colours except a little blue colour. when all these colour reaches our eyes all colour gets combined and form white light thus water seems colourless.

2) Because hydrogen and oxygen both are colourless and hence water is colourless because it is the combination of both hydrogen and oxygen.

3) It could be hereditary as our eyes first evolved in water hence our body adapted to see water colourless.

4) electron transition,unpaired or paired electron in a substance makes it coloured or colourless.If it has unpaired electron then electron transition occurs and this makes substance coloured. If it has paired electron transition not occurs and then substances will be colourless.Water has no unpaired electron so it comes in the colourless category.
