CuteRansomware Virus - How To Remove?

 

CuteRansomware derives from a Chinese open-source program titled my-Little-Ransomware. It gives the feeling that these hackers are up to their eyeballs in Hello Kitty TV series. This freakishly named ransomware primarily aims at Chinese users but its battlefield is not confined to this giant country of East Asia. You do bear the chances to encounter this digital varmint on your PC as well. CuteRansomware virus have some peculiar features never exhibited before by any other ransomware viruses.

About CuteRansomware

CuteRansomware ransomware exploits Google Docs to store the victim’s data and the private decryption key. In the latter manner, Google Docs becomes the ransomware’s C$C (Command and Control) server. This feature is particularly frightening since such cloud storages as Google Docs use SSLs (Secure Sockets Layers) to communicate with the client, which means that the communication is encrypted, that is – protected. This communication can even bypass firewalls and some antivirus systems.

Despite the previously mentioned peculiarities, cuteRansomware cryptomalware seems to act similarly to ‘‘normal’’ ransomware viruses. It uses the asymmetric encryption algorithm to damage the victim’s data. ‘‘.encrypted’’ filename extension is appended to the filename extensions of each encrypted file. For instance, video.avi is turned into video.avi.encrypted. Just this extension and the ransom note that later covers the victim’s screen are both written in Chinese. This again indicates the origin of cuteRansomware. However, the size of the ransom demanded is still a great deal of cloak-and-dagger.

Step 3. Restore CuteRansomware Virus affected files using Shadow Volume Copies

If 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 CuteRansomware 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 PropertiesPrevious 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.

There 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 Data Recovery Pro (commercial)
  • Install and scan for recently deleted files. Data Recovery Pro

Note: In many cases it is impossible to restore data files affected by modern ransomware. Thus I recommend using decent cloud backup software as precaution. We recommend checking out Carbonite, BackBlaze, CrashPlan or Mozy Home.
