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.

Have you ever imagine why our hands swinging when we are walking?

Swinging actually had a purpose,it conserves energy of our body.Yae right it conserves energy.How? Let's find out😊

Scientifically the people who hold their arms at rest while walking use 12℅ more body energy than people who swings their arms naturally.
Assume arm is like a pendulum, when our legs moves, our body also moves and that movement forces our arms(i.e. Pendulum) to swing.Now think if we stop this movement or force by doing our arms at rest means our body is applying an external energy(i.e. body energy) contrary to natural swinging in which body doesn't apply any force or energy and swings like to and fro.Thats way our body use energy when we take the hands at rest.

Swinging hands also maintain the centre of gravity of our body in an unstable place. It supplies dynamic balance to the body. If we had a tail🐒😄 we wouldn't have to swing our arms to balance our body.

If you think to go against natural arm swing to burn more calories then this can damage your spines.So guyzz hold on with your natural swing to carry on with your walk.

Judges break the nib of the pen after the death of a prisoner, why? explained.

The fact is that the act of breaking the nib of a pen is not an act under any law. It is just a belief that court follows. It is a british custom done by convention, not because of any rule. But do you imagine why they do it? So below is some reasons why they do it.

1) It is done by Judges as to distance themselves from the guilt of their judgment

2) To safeguard that none can commit such offence.

3) Breaking of nib used to express the sorrow.

4) It also declares that Judges is only carrying out his official accountability

In modern days, it has been observed that instead of breaking of nib, they throw the refill of the pen out.
Once it is declared death none can question it. Only supreme Court can override it.

Can bank account hacked by hackers if he knows account number,IFSC code,PAN number and account holder name?

I know how hard it is to earn money.You earn and money save it to the bank for future purposes but in addition you have to take care of your money.

So let's start I'm giving you the answer to the point that can anyone hack your account with these above information. So the answer is that NO ONE can missuse or hack your account with these information so take a chill-pill.No hacking can be shooted with these details. Passbooks/Checkbooks contains our bank account number,name,IFSC code and PAN number if it was supposed to be sensitive then they wouldn't brought it to light.

One can use account name and number only to transfer some bundles of money.IFSC code (Indian financial system code) which is a 11 digit alphanumeric number which shows any bank branch address,only used to locate the branch of any bank. It can be found over internet easily. So you don't have to bother about account name, number and IFSC code.

But In case of PAN number you have to little more concious.I mean not very but little bit. PAN cannot be used for withdrawal of money like credit card or debit card.PAN or permanent account number is our id in the income tax department of India.If someone has a Xerox copy of yours, he won't be able to make any use of it.It can be use in some works like taking a sim card but still he requires the photo and address proof of yours.

Some People may not be elective to get loans due to poor financial records or any other reason. Such people may try to take benefit from our PAN.These type of activities​ can only be performed by people who are close to us.So firstly we have to know the person well before giving our PAN.

We have to careful with sharing of our date of birth.Chances are also there that any unknown person with our PAN can register on the income tax site with our surname and date of birth. This type of details can easily be traced by our social profile.
Railways displaying only last digits of the PAN card so that PAN harm can be avoided.

THINGS ONE CAN DO TO AVOID THESE TYPE OF RISKS.

Bank doesn't wants any of these details over phone so don't EVER SHARE any of these below details over phone or mail to any one even to the bank employee (s).

1) Debit card/ Credit card no.

2) Debit card pin .

3) Net banking user id and passwords.

4) Cheque book or cheque signed.

5) mobile number/OTP

6) Avoid to give PAN as identity proof. Instead give other id(s) like voter ID or driving licence.

Where do deleted files go from mobiles or computer systems?

First of all they don't go anywhere they remain in the mobile phones and computers.When we delete a file, it is unreadable by the mobiles and computer.However the file is still on its memory or at some particular location,at least until other file is saved to the same location.

Further more on any hard disk there is a table stored that shows some certain file is stored at the particular location (s).When the file is deleted, the original character of the file is removed and it is marked as "unknown".Now from the next time drive knows that the location which is marked as unknown were free to be overwritten with new data.
As long as no fresh data had been written over that certain location with information, everything was still there and that's why we could recover it by data recovery software and apps.



Thanks for reading stay tuned for more awesome questions 😉😊😃

Why do Tv screens or monitors flickers when filmed by the video?

In simple thoughts TV screen's scan or refresh rate is not match with scan or refresh rate (rate at which screen data refreshes) of filming equipments (eg.camera,mobile phones).
For example-Tv screen refreshes at speed of 60fps but on a mobile phone the refresh rate is only 25fps or 30fps.
A digital/video camera is using a sensor which has the certain amount of pixels and it is capturing something that doesn't have matching number of pixels.
Another reason is that the understanding of phosphorus dots by human eyes and camera sensors are different.
Some Devices control the flicker of screen.Generally a digital signal is sent to the monitor so that it will sync with the camera.
