DBGer ransomware removal instructions
What is DBGer?
Developed using EternalBlue and Mimikatz, DBGer is a ransomware-type virus discovered by MalwareHunterTeam. Immediately after infiltration, DBGer encrypts most stored files and renames them using the "[[firstname.lastname@example.org]][original_filename].dbger" pattern. For example, "sample.jpg" is renamed to "[email@example.com]sample.jpg.dbger". Compromised data immediately becomes unusable. Following successful encryption, DBGer generates a text file ("_How_to_decrypt_files.txt") and opens it automatically.
As usual, the new text file contains a message informing victims of the encryption. To restore data, victims are encouraged to pay a ransom. Note that an identical message is delivered in three languages: English, Korean, and Chinese. Therefore, it is safe to assume that developers are from Asia or target users who live in this region. There is no additional information provided and, therefore, it is currently unknown which cryptography (symmetric or asymmetric) DBGer uses. In any case, decryption requires a unique key. Developers store all keys on a remote server. To receive them, victims are encouraged to pay a ransom of 1 Bitcoin (currently equivalent to ~$6500). It is also stated that ransoms must be paid within three days after encryption, otherwise restoring compromised data is no longer possible. Note that, as compared to other ransomware-type viruses, this cost is extremely high (ransoms typically fluctuate between $500 and $1500). Furthermore, cyber criminals can never be trusted. Research shows that these people often ignore victims, once payments are submitted. Therefore, paying typically gives no positive result and users are scammed. We strongly advise you to ignore all requests to contact these people or submit any payments. Unfortunately, there are no tools capable of cracking DBGer encryption and restoring data free of charge. Therefore, there is only one solution: to restore everything from a backup.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
DBGer is virtually identical to Gw3w, Excuses, Donut, Insta, and dozens of other ransomware-type viruses. All are developed by different cyber criminals. Despite this, their behavior is identical - all encrypt data and make ransom demands. In fact, these viruses typically have just two major differences: 1) type of used cryptography, and; 2) cost of decryption. Unfortunately, most employ algorithms such as RSA, AES, and others that generate unique decryption keys. Therefore, file decryption manually without involvement of developers (contacting these people is not recommended) is virtually impossible. The only possible scenarios are ransomware not being fully developed or having certain bugs/flaws (e.g., the key is hard-coded, stored locally or similar). This malware presents a strong case for maintaining regular data backups, however, it is very important to store them on a remote server (e.g., Cloud) or unplugged storage device (external hard drive, Flash drive or similar), otherwise backups are encrypted together with regular files.

How to protect yourself from ransomware infections?
Be aware that poor knowledge and careless behavior are the main reasons for computer infections. The key to safety is caution. Therefore, pay close attention when browsing the Internet and downloading/installing/updating software. Carefully analyze each received email attachment. If the file seems irrelevant or has been received from a suspicious/unrecognizable email address, do not open it and delete the email immediately. Furthermore, we strongly advise you to download your software from official sources only, using direct download links. Third party downloaders/installers often include rogue programs, and thus these tools should never be used. The same rule applies to software updating. Keep installed applications updated, however, this should be achieved through implemented update functions or tools provided by the official developer only. Make sure you have a reputable anti-virus/anti-spyware suite installed and running.

DBGer ransomware removal:
- What is DBGer?
- STEP 1. DBGer virus removal using safe mode with networking.
- STEP 2. DBGer ransomware removal using System Restore.
Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK. During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

Windows 8 users: Start Windows 8 is Safe Mode with Networking - Go to Windows 8 Start Screen, type Advanced, in the search results select Settings. Click Advanced startup options, in the opened "General PC Settings" window, select Advanced startup. Click the "Restart now" button. Your computer will now restart into the "Advanced Startup options menu". Click the "Troubleshoot" button, and then click the "Advanced options" button. In the advanced option screen, click "Startup settings". Click the "Restart" button. Your PC will restart into the Startup Settings screen. Press F5 to boot in Safe Mode with Networking.

Windows 10 users: Click the Windows logo and select the Power icon. In the opened menu click "Restart" while holding "Shift" button on your keyboard. In the "choose an option" window click on the "Troubleshoot", next select "Advanced options". In the advanced options menu select "Startup Settings" and click on the "Restart" button. In the following window you should click the "F5" button on your keyboard. This will restart your operating system in safe mode with networking.

1) Download and install 2) Run system scan 3) Enjoy your clean computer!
If you cannot start your computer in Safe Mode with Networking, try performing a System Restore.
Video showing how to remove ransomware virus using "Safe Mode with Command Prompt" and "System Restore":
1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.
2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.
3. Next, type this line: rstrui.exe and press ENTER.
4. In the opened window, click "Next".
5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the DBGer ransomware virus infiltrating your PC).
6. In the opened window, click "Yes".
7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining DBGer ransomware files.
To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of DBGer are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.
To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.
If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.
To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as DBGer ransomware.
Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.
Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.
HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
Malwarebytes Anti-Ransomware Beta uses advanced proactive technology that monitors ransomware activity and terminates it immediately - before reaching users' files:
- The best way to avoid damage from ransomware infections is to maintain regular up-to-date backups. More information on online backup solutions and data recovery software Here.
