This article provides information about a ransomware dubbed OXAR as well as step-by-step removal and data recovery guide.
OXAR ransomware has a new version that appends the extension .FUCK to all encrypted files. It is known that OXAR is a HiddenTear based threat which in turn means that even with several modifications the code of this new iteration could be easily cracked by security experts. Another trait of this ransomware is a ransom note file called 1 What happens with my files.txt that blackmails victims into transferring ransom to hackers’ wallet. Keep reading and learn how to remove OXAR ransomware and restore .FUCK files.

OXAR Ransomware – Distribution
Several methods could be used for the distribution of OXAR’s payload. Mainly it may be spread in email spam campaigns in the form of attached files. In order to seem legit and make you more prone to open the attached files, such emails may impersonate representatives of well-known companies or even governmental institutions. The attached malicious files usually come as documents, archives, images and other commonly used file formats. The text message may be trying to convince you that you need to download and open the attached file as soon as possible. For the sake of your security, you could use a free online file extractor each time you download new file on your PC. Tools of this kind could quickly identify whether a file contains malicious elements or not by scanning its code for particular traits. Thus it could help you to avoid opening malicious files that plague your device.
Ransomware may infiltrate computer systems with the help of corrupted web pages as well. Bad actors could inject the malicious code into the source code of target web pages or and set them to download it directly on the devices of tricked users. They could also create copies of some pages and modify their components so they can download and automatically the ransomware after a user visits the corrupted page. As regards the malicious URLs of these web pages, they could be posted on social media channels, send in emails and spread via instant messaging services. Potentially unwanted programs that alter browser settings and cause numerous redirects to sites of unknown origin are often used for ransomware distribution as well.
OXAR Ransomware – More About the Infection
The infection begins once OXAR’s payload is running on the system. The threat aims to modify some essential system settings in order to plague it and achieve persistence. It is highly possible that OXAR will add malicious values under the registry sub-keys Run and RunOnce which will ensure its automatic execution on each Windows system start.
OXAR crypto virus may also be designed to scan the system for particular details so it can then send them to its command and control server. Once the threat establishes a connection with its server, it may drop additional malicious files on the compromised host. If you want to prevent malicious intenders from stealing sensitive data of yours, you should remove all ransomware files and objects from the PC immediately after infection.
At the end OXAR crypto virus drops a ransom note file to blackmail victims into paying a ransom for a decryption solution that can decrypt .FUCK files. The message could be found in a file named 1 What happens with my files.txt. Below you could see what it reads:

No matter what hackers state, be advised to avoid ransom payment and remove the threat as soon as possible. Almost all ransomware viruses that are based on HuddenTear have been decrypted by security experts. So, the code of this new OXAR strain is expected to be cracked soon after the analyses of its samples are done. Expect us to update this article with the decryptor once it is released. Meanwhile, you could try to restore some of your .FUCK files with the help of the alternative data recovery solutions mentioned in the guide that follows.
OXAR Ransomware – Data Encryption
The encryption is applied to all types of files listed in the code of OXAR ransomware. The threat is likely to use strong cipher algorithm or combination of a few in order to modify the original code of target files and render them completely inaccessible. As OXAR is a HiddenTear based ransomware it is believed that all files that have one of the following extensions get encrypted after infection:
→.txt, .doc, .docx, .xls, .xlsx, .ppt, .pptx, .odt, .jpg, .png, .csv, .sql, .mdb, .hwp, .pdf, .php, .asp, .aspx, .html, .xml, and .psd
Once files are corrupted they all receive the specific extension .FUCK that stands at the end of their names. You cannot open .FUCK files until a proper decryption solution that reverts their code is applied. But before you rush into ransom payment be advised to check out the alternative data recovery solutions listed in the guide below. By paying the ransom you only risk to lose your money and still have your .FUCK corrupted. There is no guarantee that bad actors will provide a working solution as often the ransomware code gets broken and doesn’t generate an efficient decryption key.
Remove OXAR Ransomware and Restore Files
The step-by-step removal guide below provides both manual and automatic approaches. Beware that the removal of OXAR crypto virus is not an easy task. It is a severe threat that plagues the whole system. Security researchers recommend the help of advanced anti-malware tool for maximum efficiency.
After you fulfill the removal process make sure to check the “Restore Files” step available in our guide below. But before that be advised to back up all encrypted files to an external drive and prevent their irreversible loss.

Step 2: Uninstall OXAR and related malware from Windows
Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it. To do that:
Follow the instructions above and you will successfully delete most unwanted and malicious programs.
Step 3: Clean any registries, created by OXAR on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by OXAR there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
Step 4: Boot Your PC In Safe Mode to isolate and remove OXAR
Step 5: Try to Restore Files Encrypted by OXAR.
Method 1: Use STOP Decrypter by Emsisoft.
Not all variants of this ransomware can be decrypted for free, but we have added the decryptor used by researchers that is often updated with the variants which become eventually decrypted. You can try and decrypt your files using the instructions below, but if they do not work, then unfortunately your variant of the ransomware virus is not decryptable.
Follow the instructions below to use the Emsisoft decrypter and decrypt your files for free. You can download the Emsisoft decryption tool linked here and then follow the steps provided below:
1 Right-click on the decrypter and click on Run as Administrator as shown below:
2. Agree with the license terms:
3. Click on "Add Folder" and then add the folders where you want files decrypted as shown underneath:
4. Click on "Decrypt" and wait for your files to be decoded.
Note: Credit for the decryptor goes to Emsisoft researchers who have made the breakthrough with this virus.
Method 2: Use data recovery software
Ransomware infections and OXAR aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested a data recovery method that may help you go around direct decryption and try to restore your files. Bear in mind that this method may not be 100% effective but may also help you a little or a lot in different situations.
Simply click on the link and on the website menus on the top, choose Data Recovery - Data Recovery Wizard for Windows or Mac (depending on your OS), and then download and run the tool.
