LanRan Ransomware – Infection
LanRan ransomware could spread its infection via different methods. The payload file that initiates the malicious script for this ransomware, which in turn infects your computer machine, is circling the Internet. A few malware samples have been found by different malware researchers. You can see the VirusTotal detections for security vendors of one sample by checking the snapshot below:
LanRan ransomware could also distribute its payload file on social media sites and networks for file-sharing. Freeware that is found on the Web could be presented as useful but at the same time could hide the malicious script for the cryptovirus. Refrain from opening files just as you have downloaded them, especially if they come from suspicious sources such as links or e-mails. Instead, you should scan them beforehand with a security tool, while also checking the size and signatures of these files for anything that seems out of the ordinary. You should read the ransomware preventing tips thread in the forum.
LanRan Ransomware – More Information
LanRan ransomware is also a cryptovirus. Karsten Hahn and a few more malware researchers have discovered multiple samples of the malware. Moreover, they believe that the virus is a variant of “MyLittleRansomware”.
LanRan ransomware could make entries in the Windows Registry to achieve persistence, launch or repress processes in Windows. Some entries are designed in a way that will start the virus automatically with each launch of the Windows Operating System, such as the example provided down here:
→“HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run”
After the encryption process is finished, the ransom note will be displayed. The note is written in English. Inside, you will find instructions on what to do for file restoration. The note is contained in a file with the name @___help___@. You can preview the ransom note right down here:
The ransom note reads the following:
L_A_N_R_A_N R_A_N_S_O_M_W_A_R_E
Attention! Your Files has been encrypted By L_A_N_R_A_N@R_A_N_S_O_M_W_A_R_E##############################################################
Attention! your personal files are encrypted With RSA-2048 algorithm.

What is encryption?
Encryption is a reversible modification of information for security
reasons but providing full access to it for authorized users. To become an authorized user and keep
the modification absolutely reversible (in other words to have a possibility to decrypt your files) you
should have an individual private key. But not only it. It is required also to have the special decryption software
in “LanRan Decryptor” software for safe and complete decryption of all your files and data.##############################################################
Attention! Attention! Attention! Your Files has been encrypted By L_A_N_R_A_N_R_A_N_S_O_M_W_A_R_E And your personal files are encrypted With
RSA-2048 algorithm.

good luck
The ransom note of the LanRan virus should not be followed. In the note is stated that the only way to revert your files back to normal is if you pay 0.5 Bitcoin, which is equivalent to 525 US dollars at the time of writing this article. That is not true and you should NOT under any circumstances pay these cybercriminals. Your files may not get recovered, and nobody could give you a guarantee for that. Furthermore, giving money to these crooks will likely motivate them to create more ransomware virus or do other criminal activities.
LanRan Ransomware – Encryption Process
A list with file extensions that the LanRan ransomware seeks to encrypt isn’t known at this moment. However, the article will get duly updated if such one is discovered. The extensions which are most likely to get encrypted are the following:
→.7z, .bmp, .doc, .docm, .docx, .html, .jpeg, .jpg, .mp3, .mp4, .pdf, .php, .ppt, .pptx, .rar, .rtf, .sql, .tiff, .txt, .xls, .xlsx, .zip
Every file that gets locked will be encrypted with the RSA 2048-bit algorithm.
The LanRan cryptovirus is more than likely to erase the Shadow Volume Copies from the Windows operating system by using the following command:
→vssadmin.exe delete shadows /all /Quiet

Remove LanRan Ransomware and Restore Your Files
If your computer got infected with the LanRan 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 LanRan with SpyHunter Anti-Malware Tool
Ransomware Automatic Removal - Video Guide
Step 2: Uninstall LanRan 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 LanRan 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 LanRan 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 LanRan
Step 5: Try to Restore Files Encrypted by LanRan.
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 LanRan 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.
