Crypton virus is targeting people that favor two languages: English and Russian. Recently there has been an increase in the ransomware viruses that target Russian-speaking users and their valuable data. This variant exploits the possibilities of bringing terror to people from both camps that are the most frequently found as perfect potential victims for deception. The tension intensifies with each day when new variants of ransomware viruses get detected to be active. Constant production of these viruses is starting to spin out of control. Security researchers are unable to put an end to this war just yet. From the looks of it, the ransomware viruses are thriving and finding new “sponsors”. These supporters are usually involuntarily giving away their money to crooks: they send the money as a ransom for decryption of files. Surprisingly, it is identified that the decryption is programmed to begin automatically after hackers receive the fee for it. We express profound doubts that the creators of Crypton virus won’t bother with your problems. Once they obtain the thing they wished to (money), keeping promises becomes an unnecessary subject. Please do not become one of the supporters of ransomware viruses.

Secretive manner of proceeding is one of the instrumental features of ransomware viruses: they have to maintain their existence a secret, until they have all of the aces in their hand. Until your screen is locked with a terrifying message from the shady programmers, there is still hope to catch Crypton virus red-handed and stop it from viciously tampering with your files. If not, this virus can survive without making its presence noticeable.

Crypton virus will surely influence your Windows Registry Keys. To be more precise, it will be interested in making modifications to the entries that are responsible for getting programs automatically launched.

Its process might be spotted among the ones indicated by a Task Manager, but people are more likely to miss it. Why? Because the name of the payload can be a Plain Jane: updater.exe, installer.exe or similar. In this case, crooks are spreading crypton.exe payload. After the ransomware manages to finish up its objectives, it will reveal its presence by adding _crypt extension to all of the encoded files. In addition to that, it will leave a ransom note “readme_encryption.txt”. You are discouraged from following their advises. Images in this article show the possible ransom note and lock screens (in both English and Russian).
How is Crypton Ransomware Distributed?
Crypton virus and its payload are expected to be found in places that ransomware viruses very frequently choose to temporarily settle down. In the search of a more permanent home, it will attempt to find people who will download the payload into their system.

For this purpose, sometimes even bots are assigned to send around spam, containing malware. If you happen to receive a letter from an unknown source, claiming to discuss some important issues (taxes, flights, insurance or etc), do not open it. You should always pre-check if the sender can be counted on.

Step 3. Restore Crypton ransomware affected files using Shadow Volume CopiesIf you do not use System Restore option on your operating system, there is a chance to use shadow copy snapshots. They store copies of your files that point of time when the system restore snapshot was created. Usually Crypton ransomware tries to delete all possible Shadow Volume Copies, so this methods may not work on all computers. However, it may fail to do so. Shadow Volume Copies are only available with Windows XP Service Pack 2, Windows Vista, Windows 7, and Windows 8. There are two ways to retrieve your files via Shadow Volume Copy. You can do it using native Windows Previous Versions or via Shadow Explorer. a) Native Windows Previous Versions Right-click on an encrypted file and select Properties → Previous versions tab. Now you will see all available copies of that particular file and the time when it was stored in a Shadow Volume Copy. Choose the version of the file you want to retrieve and click Copy if you want to save it to some directory of your own, or Restore if you want to replace existing, encrypted file. If you want to see the content of file first, just click Open.
b) Shadow Explorer It is a program that can be found online for free. You can download either a full or a portable version of Shadow Explorer. Open the program. On the left top corner select the drive where the file you are looking for is a stored. You will see all folders on that drive. To retrieve a whole folder, right-click on it and select “Export”. Then choose where you want it to be stored.
Step 4. Use Data Recovery programs to recover Crypton ransomware encrypted filesThere are several data recovery programs that might recover encrypted files as well. This does not work in all cases but you can try this:
- We suggest using another PC and connect the infected hard drive as slave. It is still possible to do this on infected PC though.
- Download a data recovery program.
- Install and scan for recently deleted files.
