CryptoMix virus (.0000 and .xzzx)

CryptoMix ransomware isn’t special, and isn’t different from other suchlike viruses. We’ve made this article only to help you to remove this virus, and to familiarize you with common information about ransomware and methods to remove it.

 

 

CryptoMix ransomware penetrates user’s computers with help of different methods, but the most common of them are: infection via e-mail spam, drive-by download. All these methods are based on one simple trick: hackers try to convince the user that he needs to open the file. They say that it’s an employee’s resume, or an invoice from some client, or a form that will help to obtain a prize, or something else. If user is trustful enough to do so – ransomware infects his PC and begins to encrypt the files.

The file encryption is a very complicated process, and while it is running, you might notice that your PC is working slower than usual. Most of ransomware use AES or RSA encryption algorithms, which are the most powerful and complicated. Actually, these algorithms are even used to protect top secret files of US government, and also of governments of other countries. If we will say that this encryption is very complex – it will mean nothing. To help you understand what it is we can say that if you will use the most powerful modern personal computer, it will need thousands of years of work to bruteforce this cipher. According to this, the “decryption” doesn’t mean that some scientists will try to break the cipher, but that the malware fighters will try to hack ransomware’s C&C center to obtain a master-key for all files, encrypted by this particular virus.

This process isn’t easy, and in some cases it might take months, as we see on example of Locky and Cerber ransomware. So, the best choice for you, if you experienced CryptoMix ransomware is to remove this program, and store the encrypted files on your hard drive until the decent decryptor will be released. Now, virus adds .0000 and .xzzx extensions to all txt, doc, jpg and other important files and encrypts they. Users can find _HELP_INSTRUCTION.TXT in different folders with decryption info.
