If you have been infected by the Dharma virus, this article aims to help you remove it and try to restore the .wallet files for free.

Dharma ransomware which was latter established to be a variant of the CrySiS ransomware family has come up with yet another .wallet file extension. The Dharma virus encrypts the files on the computer which it infects by likely using the AES (Advanced Encryption Algorithm) after which holds the encrypted files hostage. It also leaves behind a ransom note in a .txt and .jpg files that demands from the victim to pay a hefty “fee” to get the files back. In case you have become victim of the Dharma ransomware virus, we suggest that you read this article to learn how to remove Dharma and try to restore your files.

Update May 2017 – New Data Recovery Method

Update May 2017. Our research indicates that this .wallet file virus continues to infect users in May 2017. In addition, there is a new ransomware infection, which uses the .wallet file extension. This new .Wallet infection encrypts the files by using the AES and RSA encryption algorithm. The ransom note is named #_Restoring_files_#.txt.

It has been brought to our attention that victims of the latest Dharma .wallet ransomware infection variants have managed to restore a very high percentage (over 90%) of their files using a very unique method – converting files into virtual drives and then using partition recovery option on data recovery programs. This method takes advantage of the converting the files into a .VHD file type which is a virtual drive. Since there are new data recovery programs specifically designed to recover partitions, one approach is to restore files encyrpted by Dharma ransomware is to convert the encrypted files into .VHD files and then try to recover them using partition recovery software. Since the algorithm that encrypts files actually alters only a small portion of the file, you have a much higher chance of recovering the files if you change them into .VHD type.

The methods have been reported to not be a full guarantee to recover all the files, but if you haven’t reinstalled your operating system yet, we advise you to follow them. But first, make sure to remove Dharma’s malicious files from the instructions at the bottom of these article. Here are the instructions:

Which Techniques Dharma Virus Uses to Spread and Infect

In order to cause a successful infection, the Dharma’s .wallet variant may utilize a mixture of tools to obfuscate the malware, such as:

• Program obfuscators.
• Exploit kit.
• File Joiners.
• Infection URLs.
• Malicious JavaScripts.
• A Database of distribution sites.
• Spamming services or spam bots.

The combination of those tools may spread Dharma ransomware in different places over the web, such as:

• Social media websites.
• Spam messages on e-mails.
• Messages on messaging services and communication programs(Skype, for example).
• Fake files uploaded on torrent websites as fake game key generators or cracks and patch-fixes.

The activation of either a malicious URL or a file leads to the devastating infection with Dharma ransomware, which makes the virus perform malicious script injection in legitimate Windows processes or services, such as sysdm.cpl or svchost.exe.

Dharma Ransomware – What Happens After Infection

After being infected by Dharma ransomware, the virus begins to perform several different tasks. For starters, it may initially create multiple objects in the Windows Registry editor. Those objects may make the ransomware virus run automatically on Windows startup and furthermore execute it’s files which it has created every time Windows boots up. Amongst the affected Windows registry entries may be the Run and RunOnce registry keys.

And when it comes to the files it creates, Dharma ransomware may create multiple files in the %Temp% and %AppData% folders. But it also may drop it’s ransom note files, which researchers claim to be named as the following:

• Readme.txt
• Readme.jpg

Furthermore, Dharma ransomware may modify the registry key for the Desktop of the computer to change the wallpaper of the affected machine to Dharma’s ransom note.

Although not confirmed, the ransom note of the virus may be similar to the other version of Dharma:

“//hallo, our dear friend!
//looks like you have some troubles with your security.
//all your files are now encrypted.
//using third-party recovering software will corrupt your data.
//you have only one way to get them back safely – using our decryption tool.
//to get original decryption tool contact us with email. In subject like write your ID, which you can find in name of every crypted file, also attach to email 3 crypted files.
[email protected]
//it is in your interest to respond as soon as pissible to ensure the restoration of your files, because we won’t keep your decryption keys at our servers more than 72 hours in interest of our security.
//P.S. only in case you don’t receive a response from the first email address within 24 hours, please use this alternative email address.
[email protected]”

In addition to this, this variant of Dharma also takes a similar approach to CrySiS XTBL when it comes to the structure of the files after encryption. They again contain the e-mail address requested for contact but they also have the unique for Dharma .wallet extension. Files encrypted by Dharma may look like the following:

After Dharma has already encrypted the files, they can no longer be opened. Their code is altered using a unique encryption algorithm.

Dharma Ransomware – Conclusion, Removal and File Restoration

Ransomware like Dharma has once proven that it can be fixed and patched to become more difficult to decrypt and for this to happen the cyber-criminals most likely have invested a lot. It is believed that the same people who are behind the notorious Shade .XTBL ransomware have managed to make a profit by simply releasing too many variants for malware researchers to track. This resulted in a lot of people paying the ransom instead of decrypting their files for free. One theory is that these money were used to create the modified version of Shade – Dharma which is currently non-decryptable.

Despite all, it is strongly advisable that you avoid paying the ransom at all costs. Malware researchers are constantly monitoring Dharma and we will update this article with free decryption instructions, just like we did with it’s previous version. In the meantime we advise you to perform the following if infected by Dharma:

1. Backup the encrypted files and create several copies of them.
2. Remove Dharma, preferably by following the instructions below.
3. Focus on trying to restore the files using alternative methods, like the ones we have suggested below in step “2. Restore files encrypted by Dharma”.

Manually delete Dharma from your computer

Note! Substantial notification about the Dharma threat: Manual removal of Dharma requires interference with system files and registries. Thus, it can cause damage to your PC. Even if your computer skills are not at a professional level, don’t worry. You can do the removal yourself just in 5 minutes, using a malware removal tool.

1. Boot Your PC In Safe Mode to isolate and remove Dharma files and objects

Boot Your PC Into Safe Mode

1. For Windows 7,XP and Vista. 2. For Windows 8, 8.1 and 10. Fix registry entries created by Dharma on your PC.

For Windows XP, Vista, 7 systems:

1. Remove all CDs and DVDs, and then Restart your PC from the “Start” menu.
2. Select one of the two options provided below:

– For PCs with a single operating system: Press “F8” repeatedly after the first boot screen shows up during the restart of your computer. In case the Windows logo appears on the screen, you have to repeat the same task again.

– For PCs with multiple operating systems: Тhe arrow keys will help you select the operating system you prefer to start in Safe Mode. Press “F8” just as described for a single operating system.

3. As the “Advanced Boot Options” screen appears, select the Safe Mode option you want using the arrow keys. As you make your selection, press “Enter“.

4. Log on to your computer using your administrator account

While your computer is in Safe Mode, the words “Safe Mode” will appear in all four corners of your screen.

Step 1: Open the Start Menu

Step 2: Whilst holding down Shift button, click on Power and then click on Restart.
Step 3: After reboot, the aftermentioned menu will appear. From there you should choose Troubleshoot.

Step 4: You will see the Troubleshoot menu. From this menu you can choose Advanced Options.

Step 5: After the Advanced Options menu appears, click on Startup Settings.

Step 6: Click on Restart.

Step 7: A menu will appear upon reboot. You should choose Safe Mode by pressing its corresponding number and the machine will restart.

Some malicious scripts may modify the registry entries of your computer to change different settings. This is why manual clean up of your Windows Registry Database is strongly recommended. Since the tutorial on how to do this is a bit lenghty, we recommend following our instructive article about fixing registry entries.

2.Find malicious files created by Dharma on your PC

Find malicious files created by Dharma

1. For Windows 8, 8.1 and 10. 2. For Windows 7,XP and Vista.

For Newer Windows Operating Systems

Step 1:

On your keyboard press  + R and write explorer.exe in the Run text box and then click on the Ok button.

Step 2:

Click on your PC from the quick access bar. This is usually an icon with a monitor and its name is either “My Computer”, “My PC” or “This PC” or whatever you have named it.

Step 3:

Navigate to the search box in the top-right of your PC’s screen and type “fileextension:” and after which type the file extension. If you are looking for malicious executables, an example may be “fileextension:exe”. After doing that, leave a space and type the file name you believe the malware has created. Here is how it may appear if your file has been found:

N.B. We recommend to wait for the green loading bar in the navination box to fill up in case the PC is looking for the file and hasn’t found it yet.

For Older Windows Operating Systems

In older Windows OS’s the conventional approach should be the effective one:

Step 1:

Click on the Start Menu icon (usually on your bottom-left) and then choose the Search preference.

Step 2:

After the search window appears, choose More Advanced Options from the search assistant box. Another way is by clicking on All Files and Folders.

Step 3:

After that type the name of the file you are looking for and click on the Search button. This might take some time after which results will appear. If you have found the malicious file, you may copy or open its location by right-clicking on it.

Now you should be able to discover any file on Windows as long as it is on your hard drive and is not concealed via special software.

2. Restore files encrypted by Dharma

Restore Files Encrypted by Dharma

Ransomware infections like Dharma aim to encrypt your files using an encryption algorithm which may be very difficult to directly decrypt. This is why we have suggested several alternative methods that may help you go around direct decryption and try to restore your files. Bear in mind that they may not be 100% effective but they may help you little or a lot in some situations.

Method 1: Scanning your drive’s sectors by using Data Recovery software.
Another method of restoring your files is by trying to bring back your files via data recovery software. Here are some suggestions for preferred data recovery software solutions:

• Stellar Phoenix Data Recovery Technicians License(Pro version with more features)
• Stellar Phoenix Windows Data Recovery
• Stellar Phoenix Photo Recovery

Method 2: Trying Kaspersky and EmsiSoft’s decryptors.
If the first method does not work, we suggest trying to use decryptors for other ransomware viruses, in case your virus is a variant of them. The two primary developers of decryptors are Kaspersky and EmsiSoft, links to which we have provided below:

• Kaspersky Decryptors
• Emsisoft Decryptors

Urgent! It is strongly advisable to first remove the Dharma threat before attempting any decryption, since it may interfere with system files and registries. You can do the removal yourself just in 5 minutes, using an advanced malware removal tool.

Method 3: Using Shadow Explorer

To restore your data in case you have backup set up, it is important to check for shadow copies in Windows using this software if ransomware has not deleted them:

• Shadow Explorer

Method 4: Finding Dharma decryption key while it communicates it via a network sniffing software.

Another way to decrypt the files is by using a Network Sniffer to get the encryption key, while files are encrypted on your system. A Network Sniffer is a program and/or device monitoring data traveling over a network, such as its internet traffic and internet packets. If you have a sniffer set before the attack happened you might get information about the decryption key. See how-to instructions below:

Instructions on How to Find Decryption Key for Files Encrypted By Ransowmare

Optional: Using Alternative Anti-Malware Tools

Remove Dharma Using Other Alternative Tools

   We have a client that was recently hit by the DHARMA strain. (accounts server) The issue that we have is how it managed to get through a very tight security platform.

   We locked Accounts down and removed Administrator privileges. In addition the “Host” that was infected does not have a mail account. We also have a multi vectored security platform that is linked to the cloud (17 best of breed AV’S that scan mail / web and endpoint protection). Which fortunately stopped it half way through the encryption. (But is is still 300Gb that needed to be restored)

   Recently we opened up RDP for a 3rd party vendor to run updates on their platform. They then got hit…
   (The 3rd party company run’s updates for 100s corporate clients – and are adamant that it is not from their side as other sites would be affected).

   My query is – how does this infection then get in? The server (2012 R2) was recently formatted and reloaded – all patches up to date, is behind a firewall, is not internet or mail facing and we have a proven solid security platform)

   RDP? Brute force attack… some kind of BOT?

   No other unit has the payload on the network.

   Is very odd… any input will be appreciated… Thanks

      You could theoretically use a network sniffer to intercept any POST communication related to Dharma, but for this you have to know the remote server it connects to and for this you have to have the malicious payload of the virus which should contain the IP or host of the C2 server in it. Then you may add it as a fiter in Wireshark and reinfect a test PC or if you have an infected computer, make Wireshark run on startup and intercept any traffic or communication packets. Below we have a theoretical tutorial on how to run wireshark on startup and how to try and detect information in packets, so feel free to help yourself. Bear in mind that you have to be infected with the thing to try this and it is only theoretical, meaning that it may or may not work, because the virus may send the information via encrypted packages or encrypt the decryption key on your computer and send it afterwards.

      I have just seen a site where I have identified RDP as the means of entry for two separate attacks. In both cases generic test accounts with an easily guessable password (hint, the user accounts are test accounts in a school). I would check, and double check that your RDP access is only allowed to specific real users, and not across the board to any domain admins and test accounts, Make sure these accounts have good passwords. Plus, ideally, do not publish RDP on it’s default port of 3389. At least change this to a different port, or better still put in a web gateway to access it.

      Take a look at a page like https://security.berkeley.edu/resources/best-practices-how-articles/securing-remote-desktop-rdp-system-administrators for more info on securing RDP.

      My next step is going to be installing App Locker on the RDP boxes to ensure that no malware can run.

      NB. If you look at the owner of the files you can find out what account was infected and caused the file encryption.
