What is .Lazarus virus .Lazarus virus is also known as .Lazarus ransomware and encrypts users’ files while asking for a ransom.
.Lazarus virus is a new malware threat that is descendant from the Ouroboros ransomware which is being sent to targets across the world. It is a complex ransomware that is distributed via various methods. It can lead to many serious system issues and can even install other malware threats. When it has completed running all of its modules it will proceed with the file encryption making sensitive user data inaccessible. The victims will be left with .Lazarus extension encrypted data and a ransomware note and/or a lockscreen instance.

.Lazarus virus – Detailed Description
The .Lazarus virus is a new threat based on the Ouroboros ransomware family. It is anticipated that this virus will be modeled after the typical model used by ransomware. There is no information available about the hacker or the criminal group behind it. Due to it being a newer iteration of a well-known threat we expect that it will follow the same distribution techniques as its predecessors. This includes the sending out of phishing messages via emails and the construction of hacker-made sites that attempt to manipulate the victims into believing that they are receiving notifications from a legitimate service or company. When the users interact with any of them the associated .Lazarus virus engine will be started.
In addition the hackers can also embed the necessary installation scripts into file carriers — they can be various executables or documents that will lead to the virus infection once the users interact with them. A prime example is the inclusion of the virus macros across all popular document formats: text files, spreadsheets, presentations and databases. The other popular technique relies on the inclusion of the associated virus infection code in application installers. The hackers will generally target popular software that is frequently obtained by end users.
The .Lazarus virus can be contained also by browser hijackers which are dangerous plugins made for most of the popular web browsers. The criminals will post these extensions to the respective plugin reposoitories. They are commonly posted with fake user reviews and developer credentials and attempt to manipulate the victims into believing that they are installing an useful extension.
As soon as the .Lazarus virus is installed on a given computer it will execute its built-in sequence of malicious components. A common infiltration with ransomware of the Ouroboros family of threats may include any of the following:
- Data Retrieval — The .Lazarus virus can be set to extract a lot of sensitive information from the compromised hosts. This can include a list of the installed hardware components which is used to create a complete profile of the infected computers. What’s particularly worrying is when this module is programmed to collect information about the victims: the data can be used for various crimes such as identity theft and financial abuse.
- Persistent Threat Installation — If installed in an appropriate way the .Lazarus virus can be deployed as a persistent threat. This means that it will modify the boot options in order to start itself automatically as soon as the computer is powered on. It can also block access to the recovery boot options making it very hard to follow the usual manual user recovery guides.
- Windows Registry Changes — The .Lazarus virus can create new strings or edit out existing ones in the Windows Registry. The consequences of this action can lead to severe performance issuses, the inability to access certain functions and data loss.
- Additional Malware Delivery — The made infections can be used to deploy other viruses to the hosts: Trojans, cryptocurrency miners and etc.
As soon as the .Lazarus virus is deployed onto a given host and has executed all of its built-in modules it will start with the file encryption process. It will be based on a built-in list of target file type extensions that are to be affected: documents, multimedia files, backups, archives, databases and etc. All of the victim files will be renamed with the .Lazarus extension. A ransomware note will be crafted to manupulate the victims into paying the hackers a “decryption restore fee”.
.Lazarus virus – What Does It Do?
The .Lazarus virus is a crypto virus programmed to encrypt user data. As soon as all modules have finished running in their prescribed order the lockscreen will launch an application frame which will prevent the users from interacting with their computers. It will display the ransomware note to the victims.
You should NOT under any circumstances pay any ransom sum. Your files may not get recovered, and nobody could give you a guarantee for that.
The .Lazarus virus cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:
→vssadmin.exe delete shadows /all /Quiet
If your computer device was infected with this ransomware and your files are locked, read on through to find out how you could potentially restore your files back to normal.

Step 2: Uninstall .Lazarus virus 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 .Lazarus virus 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 .Lazarus virus 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 .Lazarus virus
Step 5: Try to Restore Files Encrypted by .Lazarus virus.
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 .Lazarus virus 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.
