NoobCrypt Ransomware - How To Remove?

 

NoobCrypt ransomware (a Romanian one) bears its name from its cheeky behavior. If a victim happens to use a wrong decryption key, this cryptomalware calls him/her a noob. NoobCrypt ransomware virus damages the victim’s data using asymmetric encryption algorithm. This cryptography brings into play two keys: one for encryption and one for decryption. The latter key is hidden in the remote servers controlled by the developers of this bloodsucker virus. This key is charged. Ironically, the hackers behind NoobCrypt encrypter do not know themselves for how much.

About NoobCrypt Ransomware

NoobCrypt is written in .NET programming language. This crypto malware appends ‘‘.crypt’’ or ‘‘.locky’’ extensions to the filename extensions of every encrypted file. For example, song.mp3 is converted into song.mp3.crypt or song.mp3.locky. NoobCrypt targets multiple file types, including various formats of text, image, audio, video files, archives, etc. However, it seems that the cyber crooks behind it can be named noobs themselves as the ransomware they developed has flaws in its code. The same is to be said about the ransom they demand for the decryption of the data. The size of the ransom is topsy-turvy. On the one hand, the hackers ask for 299 USD. On the other hand, they want to get 250 NZD (New Zealand Dollars). The thing is that the New Zealand Dollar has lower currency rate than the US Dollar. Does it make sense? Not, really. How can you expect such master accountants to give you your data back?

As usual, the ransom must be payed in bitcoins. The payment is to be transferred within 48 hours. The ransom note also contains a stopwatch to make the victim haste into making the payment. It is threatened that every 2 hours some amount of files will be lost permanently. The message, covering the desktop, reads as follows:

Your personal files is are encrypted!
Coded in R0MANIA
Your documents, photos, databases and other important files have been encrypted with strongest encryption and unique key, generated for this computer.
Private decryption key is stored on a secret Internet server and nobody can decrypt your files until you pay and obtain the private key.
You have 48 hours to pay 250 NZD in Bitcoins to get the decryption key.

But, as you know, haste makes waste. And that is perfectly true in this case. Because you will only loose your money, scarcely ever these cyber criminals will provide you with the working decryption key.

How is NoobCrypt Ransomware Distributed?

Another way NoobCrypt encoder can board your computer is through visiting websites which are corrupted with the malicious code of the virus. These often include social media sites and file-sharing domains, such as torrents, for instance.

Step 3. Restore NoobCrypt Ransomware 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 NoobCrypt 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.


Previous version
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 NoobCrypt Ransomware encrypted files

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.
