LambdaLocker Ransomware – Distribution
The LambdaLocker ransomware can be distributed by utilizing various methods. The most common way of distribution is probably by a file that drops the payload of the ransomware, which contains the malicious script of the virus.
LambdaLocker could also be distributing that payload dropper on social media networks and file-sharing sites. Freeware programs found on the Web could be promoted as helpful but also could be hiding the downloader for the payload. Do not open files right after you have downloaded them, especially if they come from a suspicious source, like an e-mail from an unknown sender. Instead, you should first scan those files with a security program and check their size and signatures for each of file for anything that seems unusual. You should read the tips for preventing ransomware topic.
LambdaLocker Ransomware – Information
LambdaLocker ransomware is also a cryptovirus. China seems to be the primary country that it is currently targeting, according to malware researchers. There is also the evidence that the ransom note has a variant written in the Chinese language. That doesn’t mean that other countries are excluded from its crosshairs – everybody can become a victim. The ransomware will encrypt files on your computer system and append the same extension to all of them when the encryption process finishes.
LambdaLocker ransomware could make new entries in the Windows Registry to achieve perseverance. Those registry entries are usually placed for the reason to start the virus automatically with each boot of the Windows Operating System.
The ransom note will appear after the encryption process is fully completed. The note states what the demands of the cybercriminals are, like what is the price of the ransom and all other instructions for decrypting your data. The note is contained in a file called READ_IT.hTmL. You can preview the ransom note in the screenshot provided down below:
The ransom note reads:
!!!WARNING!!!
Your files are encrypted by the LambdaLocker.
Your ID: [Redacted] We used AES-256 and SHA-256 cipher to encrypt. So DO NOT try to crack your files.

The criminals that stand behind the LambdaLocker ransomware virus want 0.5 BitCoin for decryption, which is a bit more than 400 US dollars. You should NOT under any circumstances pay these criminals. Nobody can guarantee if your files will get restored back to normal. Plus, you should not ever give money to criminals, as this will probably just support them and inspire them to make other ransomware viruses or do more criminal activities.
At this time, there is no existing list with file extensions that the LambdaLocker ransomware searches to encrypt. The article will get updated if any information on that matter surfaces.
Each file that gets encrypted will receive the same extension appended to each of them, which is .lambda_l0cked. The encryption algorithm is a mixture of the 256-bit AES and 256-bit SHA algorithms or at least, that is what is says in the ransom note.
The LambdaLocker cryptovirus is very likely to delete the Shadow Volume Copies from the Windows operating system by using this command in the Command Prompt:
→vssadmin.exe delete shadows /all /Quiet
Keep on reading and check out what kind of ways you can try to potentially restore some of your data.
Remove LambdaLocker Ransomware and Restore .lambda_l0cked Files
If your computer got infected with the LambdaLocker ransomware virus, you should have a bit of experience in removing malware. You should get rid of this ransomware as quickly as possible before it can have the chance to spread further and infect other computers. You should remove the ransomware and follow the step-by-step instructions guide provided below.
- Step 1
- Step 2
- Step 3
- Step 4
- Step 5
Step 1: Scan for LambdaLocker with SpyHunter Anti-Malware Tool
Ransomware Automatic Removal - Video Guide
Step 2: Uninstall LambdaLocker 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 LambdaLocker 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 LambdaLocker 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 LambdaLocker
Step 5: Try to Restore Files Encrypted by LambdaLocker.
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:

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 LambdaLocker 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.
