What is a .WNCRY file?
A .WNCRY file is a type of file that has been locked by a harmful computer program called Wana Decrypt0r 2.0. This program is a kind of ransomware, which means it's designed by people who want to make money by locking files on your computer and then asking you to pay them to unlock these files. The .WNCRY file used to be a normal file like a document, picture, music, or spreadsheet, but it got changed into a .WNCRY file because the ransomware scrambled it with very strong codes that are hard to break, using something called RSA algorithm and AES-128 ciphers.
This problem with .WNCRY files became a big deal around the year 2017. Once a file is turned into a .WNCRY file, you can't open it like you normally would. The ransomware also creates a note in a .TXT file telling you that your files are locked and asking for money to unlock them. However, paying the ransom is risky and not recommended because it doesn't guarantee your files will be unlocked and it encourages the criminals.
To open a .WNCRY file, you would need special tools designed to decrypt, or unlock, the files that Wana Decrypt0r 2.0 has affected. These tools are known as WannaCry Decryption Tools. Another way to try to fix the problem is by using a feature on your computer called System Restore, which might help you return your computer to a state before the files were locked, but this doesn't always work for everyone.
Wana Decrypt0r 2.0 usually gets onto a computer when someone accidentally opens a bad email attachment that looks harmless but isn't. It can also sneak in through fake updates for your computer or through files downloaded from unreliable websites. It's very sneaky and causes a lot of trouble, so it's important to be careful about what you download and open on your computer.
