What is a .RYK file?
An .RYK file is a type of file that has been changed and locked by a harmful computer program called Ryuk ransomware. This bad software is made and spread by people who do bad things online. When they attack your computer with Ryuk ransomware, they take your normal files, like documents or databases, and lock them so you can't use them anymore. They change the name of your files to end with .RYK, showing that the files are locked.
Unfortunately, once your files are changed to .RYK files, there isn't a program that can open or fix them. This is because the bad software uses a very strong lock that nobody has found a key for.
Ryuk ransomware first became a problem in 2018. It's named after a character from a comic book called Death Note. The character is known for being very powerful and dangerous, similar to how this ransomware works. The people who spread Ryuk usually go after big companies or organizations that have a lot of important files and money. They sneak into the computer systems, lock the important files, and then ask for money to unlock them. They usually want to be paid in Bitcoin, a type of digital money.
The way Ryuk gets onto computers is often through tricky emails that trick people into letting it in. But in 2021, a new version of Ryuk was found that could spread by itself from one computer to another in the same network. This means even if you are very careful, your computer could still get infected if another computer on your network is infected.
It's very important to be careful and protect your computer from these kinds of attacks. Always keep your software updated, don't open suspicious emails, and make sure you have good antivirus software. If your files ever do get locked by Ryuk, experts say you shouldn't pay the ransom because it encourages the bad guys and doesn't guarantee you'll get your files back.
