Moonshadow ransomware - Quick Decryption Solution
Moonshadow virus Removal Guide
What is Moonshadow ransomware?
Moonshadow ransomware locks data and demands Bitcoin payments for the exchange of an alleged decryption tool
The message form virus creators appearing as a pop-up
Moonshadow ransomware is the threat that encrypts files using army-grade algorithms. These particular powerful tools allow the virus to alter the original code of the file and then make the file useless. Locked data appears damaged cannot be opened and receives a marker .moonshadow at the end of the original file name right after the file type extension. This is the purpose for later ransom demands.
Moonshadow ransomware virus creates the unique victims' id, and the contact email also gets included in the appendix, so the simple filename becomes a lengthy line of characters. Once that is done, the virus releases a ransom note file on the system, and the pop-up window shows the money demanding message.
The same text and a message from criminals appear in the Decryption-Guide.txt file that gets placed on the desktop and on other folders containing the Moonshadow file virus-locked data. These messages might be scary enough, so you consider paying the demanded sum. That is not recommended.
Details on the file-locker virus
Moonshadow ransomware virus is a threat similar to VoidCrypt/ Void ransomware because it is developed by the same creators and criminals. This is not a positive fact for victims because more advanced threats and more dangerous criminals mean the more difficult removal of the infection.
|File marker||.moonshadow and includes victims' ID and contact email|
|Ransom note||Decryption-Guide.HTA and Decryption-Guide.txt|
|Removal||Threats best removed using AV tools|
|System repair||Repair of the damaged system data is possible with RestoroIntego|
Victims are always advised not to modify files and avoid renaming those locked files by virus creators. Attempts to decrypt files can cause permanent losses of data, according to the Moonshadow ransomware creators. However, paying criminals and not getting files decrypted can cause permanent money and data loss.
The ransom note that the infection places on the system to scare victims, reads:
Your Files Are Has Been Locked
Your Files Has Been Encrypted with cryptography Algorithm
If You Need Your Files And They are Important to You, Dont be shy Send Me an Email
Send Test File + The Key File on Your System (File Exist in C:/ProgramData example : KEY-SE-24r6t523 or RSAKEY.KEY) to Make Sure Your Files Can be Restored
Make an Agreement on Price with me and Pay
Get Decryption Tool + RSA Key AND Instruction For Decryption Process
1- Do Not Rename or Modify The Files (You May loose That file)
2- Do Not Try To Use 3rd Party Apps or Recovery Tools ( if You want to do that make an copy from Files and try on them and Waste Your time )
3-Do not Reinstall Operation System(Windows) You may loose the key File and Loose Your Files
4-Do Not Always Trust to Middle mans and negotiators (some of them are good but some of them agree on 4000usd for example and Asked 10000usd From Client) this Was happened
Your Case ID : –
Moonshadow ransomware demands payments and claims to have the only decryption tool that is capable of recovering all files that got affected during the encryption. This is a criminal tactic that can also involve test decryption offers or ransom discounts or just saying that you need to write them to negotiate.
This way, creators try to trick you into contacting them via emails or other platforms, so the convincing extortionist makes you believe those claims, and money gets transferred. However, once money is in their wallet, criminals disappear. Do not consider these options.
The ransom note message can be scary, but you should never pay the demanded sum
Remove the infections
Moonshadow ransomware virus is a dangerous threat that can be distributed using various other vectors, so the infection should be treated as soon as those files get encoded. You might not receive any other indications of the infection because the ransomware manages to run on the system and lock files silently.
Keeping anti-malware tools, in general, is a great habit because it is possible to avoid malware infections when these applications are running scans more often. The Moonshadow ransomware removal process can seem difficult or impossible, but it is doable. Especially when detection rates show success.
However, you should note that removing the virus is not the same as file recovery or decryption. These are needed steps because the threat can run another encryption on files that are newly restored. Run SpyHunter 5Combo Cleaner or Malwarebytes and scan the machine for any infections or malicious files.
AV detection rate indicates that antivirus tools are best for the virus removal
Restore affected system data
Victims might not notice, bet the Moonshadow file virus is capable of damaging the machine further than those locked documents or images, or archives. It injects additional malware into the machine to keep its persistence. Experts note that you should keep clearing the virus until the machine is virus-free and only then rely on file recovery.
Moonshadow ransomware can alter the Windows registry database, damage vital bootup, and other sections, delete or corrupt DLL files, etc. Once a system file is damaged by malware, antivirus software is not capable of doing anything about it, leaving it just the way it is. Consequently, users might experience performance, stability, and usability issues, to the point where a full Windows reinstallation is required.
Therefore, we highly recommend using a one-of-a-kind, patented technology of RestoroIntego repair. Not only can it fix virus damage after the infection, but it is also capable of removing malware that has already broken into the system thanks to several engines used by the program. Besides, the application is also capable of fixing various Windows-related issues that are not caused by malware infections, for example, Blue Screen errors, freezes, registry errors, damaged DLLs, etc.
- Download the application by clicking on the link above
- Click on the ReimageRepair.exe
- If User Account Control (UAC) shows up, select Yes
- Press Install and wait till the program finishes the installation process
- The analysis of your machine will begin immediately
- Once complete, check the results – they will be listed in the Summary
- You can now click on each of the issues and fix them manually
- If you see many problems that you find difficult to fix, we recommend you purchase the license and fix them automatically.
Try to find a decryptor
Moonshadow ransomware virus is not decryptable and the family it is coming from is known for a while. These tools take a long time to develop and law enforcement needs to obtain the decryption codes and disrupt operations for the development of universal tools for all the versions. These days ransomware gets more and more advanced.
File encryption is a process that is similar to applying a password to a particular file or folder. However, from a technical point of view, encryption is fundamentally different due to its complexity. By using encryption, threat actors use a unique set of alphanumeric characters as a password that can not easily be deciphered if the process is performed correctly.
There are several algorithms that can be used to lock data (whether for good or bad reasons); for example, AES uses the symmetric method of encryption, meaning that the key used to lock and unlock files is the same. Unfortunately, it is only accessible to the attackers who hold it on a remote server – they ask for a payment in exchange for it. This simple principle is what allows ransomware authors to prosper in this illegal business.
While many high-profile ransomware strains such as Djvu or Dharma use immaculate encryption methods, there are plenty of failures that can be observed within the code of some novice malware developers. For example, the keys could be stored locally, which would allow users to regain access to their files without paying. In some cases, ransomware does not even encrypt files due to bugs, although victims might believe the opposite due to the ransom note that shows up right after the infection and data encryption is completed.
Therefore, regardless of which crypto-malware affects your files, you should try to find the relevant decryptor if such exists. Security researchers are in a constant battle against cybercriminals. In some cases, they manage to create a working decryption tool that would allow victims to recover files for free.
Once you have identified which ransomware you are affected by, you should check the following links for a decryptor:
- No More Ransom Project
- Free Ransomware Decryptors by Kaspersky
- Free Ransomware Decryption Tools from Emsisoft
- Avast decryptors
If you can't find a decryptor that works for you, you should try the alternative methods we list below. Additionally, it is worth mentioning that it sometimes takes years for a working decryption tool to be developed, so there are always hopes for the future.
Do not skip on the system scan using Malwarebytes or SpyHunter 5Combo Cleaner anti-malware tools. This can ensure that the Moonshadow ransomware virus is removed with all the related files and intruders. Besides malicious files, there might be damaged system data, so running a scan with RestoroIntego is also recommended. Then you can worry about files that got encrypted.

Important steps to take before you begin malware removal
File encryption and ransomware infection are two independent processes (although the latter would not be possible without the former). However, it is important to understand that malware performs various changes within a Windows operating system, fundamentally changing the way it works.
IMPORTANT for those without backups! →
If you attempt to use security or recovery software immediately, you might permanently damage your files, and even a working decryptor then would not be able to save them.
Before you proceed with the removal instructions below, you should copy the encrypted files onto a separate medium, such as USB flash drive or SSD, and then disconnect them from your computer. Encrypted data does not hold any malicious code, so it is safe to transfer to other devices.
The instructions below might initially seem overwhelming and complicated, but they are not difficult to understand as long as you follow each step in the appropriate order. This comprehensive free guide will help you to handle the malware removal and data recovery process correctly.
If you have any questions, comments, or are having troubles with following the instructions, please do not hesitate to contact us via the Ask Us section.
It is vital to eliminate malware infection from the computer fully before starting the data recovery process, otherwise ransomware might re-encrypt retrieved files from backups repeatedly.
Identify ransomware affecting your PC
Modern-day ransomware had its roots in the early 2010s when cybercriminals began to understand the potential it has for money extortion. Over the years, thousands of new ransomware strains have been developed and spread all over the world, infecting regular consumers, small businesses, and high-profile organizations.
Because of the lucrative nature of ransomware, cybercriminals are creating new ransomware versions in the hopes of establishing themselves in this illegal business. Ransomware often uses different extensions, ransom notes, and other attributes that it can be identified by. However, quite often, this information can overlap or simply not be available, so identifying the threat might be difficult.
In order to deal with ransomware infection effectively, you must first identify it. Here are a few examples of how to determine the precise ransomware you are dealing with:
Almost all modern ransomware viruses are using extensions that are appended at the end of the original filenames. However, this is not a rule, and in some cases, cybercriminals change the name by replacing it with randomly generated characters, add the marker before the file name, or do not visually change the name of the file at all.
Here you can see an example of a unique extension .hhmgzyl that belongs to the Snatch ransomware family:
If your files are appended with .exe, .locked, .encrypted, or other broadly-used extensions that are difficult to identify, proceed with the next step.
Ransomware family might sometimes be identified by the ransom note it uses. In most cases, cybercriminals create a simple .txt file and place it on users' desktops or other places that are easily reachable (typically, where the encrypted data is located). Other times, a pop-up window can also be used, which is launched as soon as the encryption is complete. In some cases, threat actors name the ransomware within this note:
In some cases, it is possible to identify ransomware by its ransom note name, but they are typically very generic (e.g., FILES ENCRYPTED.txt, _readme.txt) and used by different cybercriminals groups.
Free ID Ransomware service
ID Ransomware is a free service that can easily let users identify the precise malware they are dealing with. All you have to do is upload the ransom note that can be found on the desktop and within folders where encrypted files are located and the sample of an encrypted file.
Soon after uploading the required files, you will be provided with all the relevant information, including what family ransomware belongs to and whether or not it is possible to decrypt files.
If none of the above helped you to identify which ransomware you are dealing with, you should use keywords (extension, contact email, ransom note contents, crypto-wallet address, etc.) to find the information on the internet.
Restore Windows "hosts" file to its original state
Some ransomware might modify Windows hosts file in order to prevent users from accessing certain websites online. For example, Djvu ransomware variants add dozens of entries containing URLs of security-related websites, such as 2-spyware.com. Each of the entries means that users will not be able to access the listed web addresses and will receive an error instead.
Here's an example of “hosts” file entries that were injected by ransomware:
In order to restore your ability to access all websites without restrictions, you should either delete the file (Windows will automatically recreate it) or remove all the malware-created entries. If you have never touched the “hosts” file before, you should simply delete it by marking it and pressing Shift + Del on your keyboard. For that, navigate to the following location:
Restore files using data recovery software
Since many users do not prepare proper data backups prior to being attacked by ransomware, they might often lose access to their files permanently. Paying criminals is also very risky, as they might not fulfill the promises and never send back the required decryption tool.
While this might sound terrible, not all is lost – data recovery software might be able to help you in some situations (it highly depends on the encryption algorithm used, whether ransomware managed to complete the programmed tasks, etc.). Since there are thousands of different ransomware strains, it is immediately impossible to tell whether third-party software will work for you.
Therefore, we suggest trying regardless of which ransomware attacked your computer. Before you begin, several pointers are important while dealing with this situation:
- Since the encrypted data on your computer might permanently be damaged by security or data recovery software, you should first make backups of it – use a USB flash drive or another storage.
- Only attempt to recover your files using this method after you perform a scan with anti-malware software.
Install data recovery software
- Download Data Recovery Pro.
- Double-click the installer to launch it.
- Follow on-screen instructions to install the software.
- As soon as you press Finish, you can use the app.
- Select Everything or pick individual folders where you want the files to be recovered from.
- Press Next.
- At the bottom, enable Deep scan and pick which Disks you want to be scanned.
- Press Scan and wait till it is complete.
- You can now pick which folders/files to recover – don't forget you also have the option to search by the file name!
- Press Recover to retrieve your files.
Create data backups to avoid file loss in the future
One of the many countermeasures for home users against ransomware is data backups. Even if your Windows get corrupted, you can reinstall everything from scratch and retrieve files from backups with minimal losses overall. Most importantly, you would not have to pay cybercriminals and risk your money as well.
Therefore, if you have already dealt with a ransomware attack, we strongly advise you to prepare backups for future use. There are two options available to you:
- Backup on a physical external drive, such as a USB flash drive or external HDD.
- Use cloud storage services.
The first method is not that convenient, however, as backups need to constantly be updated manually – although it is very reliable. Therefore, we highly advise choosing cloud storage instead – it is easy to set up and efficient to sustain. The problem with it is that storage space is limited unless you want to pay for the subscription.
Using Microsoft OneDrive
OneDrive is a built-in tool that comes with every modern Windows version. By default, you get 5 GB of storage that you can use for free. You can increase that storage space, but for a price. Here's how to setup backups for OneDrive:
- Click on the OneDrive icon within your system tray.
- Select Help & Settings > Settings.
- If you don't see your email under the Account tab, you should click Add an account and proceed with the on-screen instructions to set yourself up.
- Once done, move to the Backup tab and click Manage backup.
- Select Desktop, Documents, and Pictures, or a combination of whichever folders you want to backup.
- Press Start backup.
After this, all the files that are imported into the above-mentioned folders will be automatically backed for you. If you want to add other folders or files, you have to do that manually. For that, open File Explorer by pressing Win + E on your keyboard, and then click on the OneDrive icon. You should drag and drop folders you want to backup (or you can use Copy/Paste as well).
Using Google Drive
Google Drive is another great solution for free backups. The good news is that you get as much as 15GB for free by choosing this storage. There are also paid versions available, with significantly more storage to choose from.
You can access Google Drive via the web browser or use a desktop app you can download on the official website. If you want your files to be synced automatically, you will have to download the app, however.
- Download the Google Drive app installer and click on it.
- Wait a few seconds for it to be installed.
- Now click the arrow within your system tray – you should see Google Drive icon there, click it once.
- Click Get Started.
- Enter all the required information – your email/phone, and password.
- Now pick what you want to sync and backup. You can click on Choose Folder to add additional folders to the list.
- Once done, pick Next.
- Now you can select to sync items to be visible on your computer.
- Finally, press Start and wait till the sync is complete. Your files are now being backed up.
Report the incident to your local authorities
Ransomware is a huge business that is highly illegal, and authorities are very involved in catching malware operators. To have increased chances of identifying the culprits, the agencies need information. Therefore, by reporting the crime, you could help with stopping the cybercriminal activities and catching the threat actors. Make sure you include all the possible details, including how did you notice the attack, when it happened, etc. Additionally, providing documents such as ransom notes, examples of encrypted files, or malware executables would also be beneficial.
Law enforcement agencies typically deal with online fraud and cybercrime, although it depends on where you live. Here is the list of local authority groups that handle incidents like ransomware attacks, sorted by country:
- USA – Internet Crime Complaint Center IC3
- United Kingdom – ActionFraud
- Canada – Canadian Anti-Fraud Centre
- Australia – ScamWatch
- New Zealand – ConsumerProtection
- Germany – Polizei
- France – Ministère de l'Intérieur
If your country is not listed above, you should contact the local police department or communications center.
Manual removal using Safe Mode
Manual removal guide might be too complicated for regular computer users. It requires advanced IT knowledge to be performed correctly (if vital system files are removed or damaged, it might result in full Windows compromise), and it also might take hours to complete. Therefore, we highly advise using the automatic method provided above instead.
Step 1. Access Safe Mode with Networking
Manual malware removal should be best performed in the Safe Mode environment.
Windows 7 / Vista / XP
- Click Start > Shutdown > Restart > OK.
- When your computer becomes active, start pressing F8 button (if that does not work, try F2, F12, Del, etc. – it all depends on your motherboard model) multiple times until you see the Advanced Boot Options window.
- Select Safe Mode with Networking from the list.
Windows 10 / Windows 8
- Right-click on Start button and select Settings.
- Scroll down to pick Update & Security.
- On the left side of the window, pick Recovery.
- Now scroll down to find Advanced Startup section.
- Click Restart now.
- Select Troubleshoot.
- Go to Advanced options.
- Select Startup Settings.
- Press Restart.
- Now press 5 or click 5) Enable Safe Mode with Networking.
Step 2. Shut down suspicious processes
Windows Task Manager is a useful tool that shows all the processes running in the background. If malware is running a process, you need to shut it down:
- Press Ctrl + Shift + Esc on your keyboard to open Windows Task Manager.
- Click on More details.
- Scroll down to Background processes section, and look for anything suspicious.
- Right-click and select Open file location.
- Go back to the process, right-click and pick End Task.
- Delete the contents of the malicious folder.
Step 3. Check program Startup
- Press Ctrl + Shift + Esc on your keyboard to open Windows Task Manager.
- Go to Startup tab.
- Right-click on the suspicious program and pick Disable.
Step 4. Delete virus files
Malware-related files can be found in various places within your computer. Here are instructions that could help you find them:
- Type in Disk Cleanup in Windows search and press Enter.
- Select the drive you want to clean (C: is your main drive by default and is likely to be the one that has malicious files in).
- Scroll through the Files to delete list and select the following:
Temporary Internet Files
- Pick Clean up system files.
- You can also look for other malicious files hidden in the following folders (type these entries in Windows Search and press Enter):
After you are finished, reboot the PC in normal mode.
Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Moonshadow and other ransomwares, use a reputable anti-spyware, such as RestoroIntego, SpyHunter 5Combo Cleaner or Malwarebytes
How to prevent from getting ransomware
Access your website securely from any location
When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.
If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.
Recover files after data-affecting malware attacks
While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.
Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
