Read this material to learn how to remove the .CK CryptoMix ransomware variant and how to restore .CK encrypted files.
A new variant of the CryptoMix ransomware viruses has been encountered by malware research experts. The virus prays on victims whose computers are unpatched and who have nothing more than standard anti-virus protection. The .CK file virus’ main purpose is to encrypt the files on the computers that are infected by it and then extort the victim to pay a hefty ransom fee in it’s ransom note, named _HELP_INSTRUCTION.TXT. It not only adds it’s own .CK file extension to the encrypted files, but changes their names as well. If your files are encrypted by the .CK file virus, it is reccommended to read the following post.
Infects the computer after which encrypts important documents and holds them hostage until a ransom is paid.
Signs of Presence
Files are encrypted with the .CK file extension.
Via malicious e-mail spam and set of infection tools.
Vel, .CK CryptoMix works just like most ransomware viruses do – it enters your system via a compromised file or a malicious URL contained in a spam email. Be cautious when opening even the slightest suspicious email in your inbox, especially if it contains an attachment or an URL. Once the compromised file or URL is opened, the virus downloads to your system and the infection begins.
.CK CryptoMix scans your files first. It searches your PC for the following extensions:
Once detected, they are being encrypted by a powerful AES (Advanced Encryption Standard) cypher and the victim’s desktop wallpaper is changed to the .CK CryptoMix logo of the hacking group from Mr. Robot. Og, that’s how you know you got attacked by .CK CryptoMix ransomware.
What to Do If You Notice the Ransom Note of .CK CryptoMix?
When you encounter the lockdown message, it means that your PC has already been encrypted. Even if you feel like you have no other choice but to pay, you should not do it. First and most important, even if you send the hackers your money, they may not unlock your PC. And since the Bitcoin system doesn’t allow refunds, you will not be able to get your money back. Second, your cash will increase the motivation of the hackers to develop more cyber threats like .CK CryptoMix ransomware.
There are a few ways that may help you recover the lost data for free. Although this Trojan sometimes deletes the shadow volume copies, you should still attempt to restore your PC to a date prior the infection. You should also try some free decryptors, but there is no guarantee that they will be efficient. The most important step is to eliminate .CK CryptoMix as soon as possible or else it may spread to other machines and cause more damage. It will be a challenge even for the experts to delete all traces of this ransomware manually, so you should consider using a dedicated anti-malware application.
What Will Be the Consequences After .CK CryptoMix Ransomware Enters?
.CK CryptoMix performs a complex encryption process via advanced ciphers, which makes all personal files inaccessible. Men, this operation takes time. If you click on a corrupt email attachment or download fake software updates, which contain .CK CryptoMix, you may not experience any issues during the first few hours. Once the Trojan modifies the structure of your data, you will notice a lockdown message on your desktop. From this moment on, it will not be possible to open the locked files. If you lack a recent backup, you may lose crucial documents, photos, images, presentations, videos or other information. The only files that .CK CryptoMix may spare will likely be associated with essential Windows processes. If they get modified as well, your whole PC may fail to launch, which means the hackers will never receive any payments. You can easily find out which files are encrypted by .CK CryptoMix by their extension. The ransomware changes the default one to it’s own custom one.

Recover files encrypted by the .CK CryptoMix Ransomware.
Method 1:Using Shadow Explorer. In case you have enabled File history on your Windows Machine one thing you can do is to use Shadow Explorer to get your files back. Unfortunately some ransomware viruses may delete those shadow volume copies with an administrative command to prevent you from doing just that.
Method 2: If you try to decrypt your files using third-party decryption tools. There are many antivirus providers who have decrypted multiple ransomware viruses the last couple of years and posted decryptors for them. Chances are if your ransomware virus uses the same encryption code used by a decryptable virus, you may get the files back. Men, this is also not a guarantee, so you might want to try this method with copies of the original encrypted files, because if a third-party program tampers with their encrypted structure, they may be damaged permanently. Here are the vendors to look for:
Method 3: Using Data Recovery tools. This method is suggested by multiple experts in the field. It can be used to scan your hard drive’s sectors and hence scramble the encrypted files anew as if they were deleted. Most ransomware viruses usually delete a file and create an encrypted copy to prevent such programs for restoring the files, but not all are this sophisticated. So you may have a chance of restoring some of your files with this method. Here are several data recovery programs which you can try and restore at least some of your files:
