What is a .KK file?
A file that ends with .kk is a file that has been changed and locked by something called SyncCrypt ransomware. This means that the file, which could be anything like a word document, a picture, a zip file, a database, or any other kind of file, has been encrypted. This is a way for the ransomware to keep the file from being accessed normally, and it's like the file is being held for ransom. The .kk part is added to the end of the file's usual name, so it looks something like this: filename.docx.kk.
To try and fix this problem, you might use a feature on your computer called System Restore. However, it's important to know that dealing with ransomware can be very tricky and it's often best to seek help from a professional.
Here's a bit more about how this all happens: Back in 2017, some people started noticing that their computers were attacked by SyncCrypt ransomware. This ransomware goes through the files on a computer and locks them by encrypting them and changing their names to include .kk at the end. After doing this, it shows a message asking for money to unlock the files. It does this by opening a note called readme.html in the web browser and also puts a folder named README on the desktop with more details, including how much money it's asking for.
You might wonder how this ransomware gets onto a computer in the first place. It usually happens through emails that look like they're important, often pretending to be court orders with an attachment that ends in .WSF (which stands for Windows Script File). These files look official, like they're something you need to open, but they're actually a trick. When someone opens one, it starts a process that secretly downloads a .JPEG image from the internet. But this isn't just any image; it has hidden files inside it that install the ransomware on the computer.
