What is WannaCry Ransomware ?
It may come as attachment or link pretending as authentic source. Mostly it can be executable file(.exe) or .bat file pretending to be as pdf , doc , jpeg , mp4 or any other known format. Make sure you donot open any file which is not from authentic source.

When it is opened or clicked by a user , it encrypts all the files on the drive, and asks to pay money by bitcoin.

Moreover it is almost impossible to trace actual owner of bitcoin address.

However, some security researcher has reduced its effect by buying a domain specified in code and making that domain live. Basically the code was pinging for a domain to self destroy or not.

However the hackers may come with new version of code.

Wow !!! the lamp works without batteries, electricity or sunlight.
It can be a boon as around one billion people in the world still live without electricity. This means a lot of people are relying on dangerous and expensive kerosene lamps to provide them with light to study, work and cook after dark .
How ?


The lamp needs gravity to make the Led ON.

Can we recover the files that have been deleted or recover the entire drive even it is formatted ?

Answer is Yes and No.
Before going to the methodology of recovering , let us understand what happens when we delete something.

As we all know that the data is stored in the form of 0's and 1's .
If any file is to be deleted, general convention is that all 0's and 1's should be converted to 0's but don't you think it is time taking process . so when you delete the file(s) or format , then the master file table reference, which merely tells the operating system where the file was located gets removed. Essentially, you're only removing the map to the data—not the data itself—while also giving the operating system permission to overwrite that area of the hard drive.so the answer is YES as it allows us to recover the data.

How to recover the data ?
Download test disk (http://www.cgsecurity.org/wiki/TestDisk) and follow the instructions in the site

Answer is No as the entire 0's and 1's are converted to 1's if your not doing quick format .

Ever thought of controlling someone with your brain ?
Have a look at this video
http://www.ted.com/talks/greg_gage_how_to_control_someone_else_s_arm_with_your_brain

Greg Gage is on a mission to make brain science accessible to all. In this fun, kind of creepy demo, the neuroscientist and TED Senior Fellow uses a simple, inexpensive DIY kit to take away the free will of an audience member. It’s not a parlor trick; it actually works. You have to see it to believe…

Do u think it is VIRUS ?
In present days it has been observed that many of the removable drives (pen drives, memory cards) when removed from some of the systems ,the files in it gets disappeared but the properties of the drive shows some size is occupied by the files . u can recover the disappeared files by opening computer , then opening the removable disk drive and typing *.* in the search box .The files will be displayed and select all the files ,cut and paste the files in the removable disk drive location.
Refer below if u want to know why it happens
The files which appeared to be disappeared were moved to a folder named space (which can be obtained by typing Alt+255 or Alt + 0160) which is different from space generated by pressing space bar(This space cannot be used to name a folder as folder name doesn't contain spaces) and the graphical view of folder usually yellow is changed to white which in turn makes the folder invisible.Finally, u are typing *.* in the search bcoz * is a wildcard character which stands for multiple characters in windows platform.
