What is CoNFicker ransomware virus?

CoNFicker ransomware gets a backup: Saramat version emerges

Alternative Conficker ransomware names

CoNFicker virus operates as a crypto-virus [1] which encodes files and demands payment. Interestingly, it is not related with the notorious Conficker worm [2] which was one of the most active cyber infections in 2008 and 2009. Back then, the parasite has infiltrated millions of private and even state computers which resulted in the loss of over 9 billion dollars.

The virus continued to live on and evolved into a complex malware of different shapes and sizes that continues its legacy to this day. The experts are not sure whether the ransomware that shares its name also shares the same creators or the criminals have simply chosen this title due to its infamous history. Both these viruses are equally bothersome and infecting your device with either of them may result in financial losses, system damage and corrupted data.

While the activity of the malware was low since its appearance on the cyber space, developers have revived it by releasing .saramat variation. It is created on the basis of HiddenTear[3], though it has links to Ryzerlo malware as well. It presents the same old GUI. Besides its saramat.exe file, the malware also drops decrypt.txt, autorun.inf, and img.jpg files. French users[4] should be especially wary of the infection.

Thus, in this article, we will explain how to remove CoNFicker from the infected device ASAP. You can start the computer recovery by running a thorough scan of your system with antivirus software such as FortectIntego or Malwarebytes. After you are done, you may then try applying the techniques suggested at the end of the article to recover the encrypted files.

An image of the CoNFicker ransomwareIn the image above you can see CoNFicker ransomware in action. In particular, our researcher displays the ransom notes this virus uses to demand for ransom.

The working principle of this ransomware is simple: it infiltrates computers, encrypts the files it finds saved on it and then demands the victim to pay ransom for their recovery. Nevertheless, there is a lot in between that defines this particular threat. For instance, when the virus is done encrypting files, it appends .conficker extensions next to them. It also drops a ransom note called Decrypt.txt on the infected computer. The note contains the following text:

C_o_N_F_i_c_k_e_r R_A_N_S_O_M_W_A_R_E
Attention! Attention! Attention! Your Files has been encrypted By C_o_N_F_i_c_k_e_r R_A_N_S_O_M_W_A_R_E
Send 0.5 Bitcoin To @ 1sUCn6JYa7B96t4nZz1tX5muU2W5YxCmS @
If Send 0.5 Bitcoin We will send you the decryption key C_o_N_F_i_c_k_e_r Decryptor

Of course, you should not send Bitcoin [5] to the criminals’ account, nor should you use C_o_N_F_i_c_k_e_r Decryptor to unlock your files. Complying with the extortionist's demands may cause more trouble than benefit. Thus, we recommend you to perform CoNFicker removal instead. You will find suggestions on how to do that at the end of this article. So, do not waste time and get on with it!

Ransomware distribution trends

It is no longer a secret that ransomware like CoNFicker often employ Trojans [6], exploits and other deceptive techniques to spread around and infiltrate computers. Obtaining antivirus software and upgrading your general computer security may diminish the risk of such attacks, but there is always a chance you might be encroached upon.

You should acknowledge such possibility and prepare for it before it’s too late. One of the best ways to protect your data is to make a backup [7] of it and save it on some separate storage device. Data protected this way can be recovered in cases when it is accidentally deleted, corrupted or, in this particular case, encrypted by CoNFicker ransomware.

Eliminate CoNFicker infection

If you want to prepare for the CoNFicker removal in the best way possible, you should first obtain a software that you could rely upon to perform the virus elimination from the system. When such program is installed, run the full system scan with it and observe the procedure.

If you notice your antivirus cannot initiate the scan, it might be the virus is blocking it from doing that. In such a case, you will have to go through some manual decontamination steps before you are able to remove CoNFicker virus from the computer properly. Follow the instructions below not to get lost in the elimination process.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove CoNFicker from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by security experts.

If your files are encrypted by CoNFicker, you can use several methods to restore them:

Data Recovery Pro — a software that will help recover files encrypted by CoNFicker.

Data Recovery Pro is your quick recovery solution that may help restore files encrypted by the ransomware.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by CoNFicker ransomware;
  • Restore them.

Give Windows Previous Versions feature a spin and roll back your files:

Here you will learn how to use Windows Previous Versions feature and recover important files on your computer. Don't forget that this method only works if the System Restore function has been enabled pre-attack. 

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

Recover files from Volume Shadow Copies using ShadowExplorer

This method of data recovery can be applied in cases where ransomware leaves Volume Shadow Copies of the infected files in tact. If the virus destroys them, we're afraid you will have to stick to the previous two recovery options.

  • Download Shadow Explorer (;
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from CoNFicker and other ransomwares, use a reputable anti-spyware, such as FortectIntego, SpyHunter 5Combo Cleaner or Malwarebytes

How to prevent from getting ransomware

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.


Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
