In this you will find specific details about ATKL ransomware, its removal from the infected PC and the recovery of .ATKL files.
ATKL Ransomware
The ATKL ransomware is a new strain of Matrix ransomware. An infection with ATKL ransomware leads to the corruption of both essential system settings and personal files. As a result, victims are forced to pay a ransom fee to hackers via a ransom note called !ATKL_INFO!.rtf. In answer to the ransom payment, hackers should send a tool that is supposedly able to decrypt corrupted files. Since the ATKL ransomware also dubbed the ATKL virus is developed to corrupt valuable files with the help of two sophisticated cipher algorithms, it leaves them completely inaccessible. Corrupted files receive three malicious extensions the last of which is .ATKL

ATKL Virus (Matrix Ransomware) – Propagation and Imact
The ATKL ransomware’s delivery on operating systems is believed to be realized via malwspam mainly. This method enables bad actors to send spam email messages to a large number of people around the globe. Typically, these messages pretend to be sent by legitimate companies and businesses. They may pose as representatives of your internet provider, well-known bank, a popular website you visit, popular delivery company or a governmental institution.
These email messages usually contain vivid call-to-action in their text message. They may be designed in a way to trick you to download and open an attached file or click a presented link. In case that you decide to follow the instructions, you fall victim to ATKL ransomware by granting it access to your system.
Once executed on an operating system, the so-called ATKL virus known to be a Matrix ransomware strain, creates lots of additional malicious files. Тhere are several folders that are likely to be affected:
- %AppData%
- %Local%
- %LocalLow%
- %Roaming%
- %Temp%
- %Windows%
Afterward, the initial payload file triggers certain commands that execute malicious files in a predefined order. This sequence of malicious operations enables the ATKL ransomware to plague essential system components and complete its attack.
As a strain of Matrix ransomware, the ATKL virus is likely to apply a combination of two sophisticated cipher algorithms (AES-128 + RSA-2048) to encrypt target types of files.
During data encryption process the ransomware transforms parts of the original code of target files in order to restrict users’ access to their data. Unfortunately, an infection with this crypto virus could lead to the corruption of some of the most valuable files including but not limiting to:
- Audio files
- Video files
- Document files
- Image files
- Backup files
- Banking credentials, etc
Upon encryption, all corrupted files appear with three extensions – .[atomickule@cock.li].ZwjuqhUS-Nxw47YpG.ATKL. The encryption process is followed by the generation of a unique decryption key that should supposedly be able to recover encrypted files. However, you should not believe hackers as they could trick you by sending a broken decryption key that leaves your .ATKL files encoded.
Soon after the ransomware completes system and data modifications it drops a ransom note file called !ATKL_INFO!.rtf. The file may be placed in one or several folders. The text presented by this message acknowledges the presence of ATKL ransomware on the system and blackmails victims into paying a certain ransom for a decryption solution. Here is a copy of its text:

Step 2: Uninstall ATKL ransomware 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 ATKL ransomware 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 ATKL ransomware 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 ATKL ransomware
Step 5: Try to Restore Files Encrypted by ATKL ransomware.
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 ATKL ransomware 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.
