DiskDoctor ransomware – a new addition to Scarab virus family

DiskDoctor Ransomware

Disk Doctor ransomware is a file-encrypting virus that belongs to the group of Scarab ransomware viruses. The virus came to the world in June 2018 and started encrypting victims' files with AES cipher. During the encryption, it adds .DiskDoctor file extension to each document, picture or other records. As soon as ransomware[1] finishes encrypting files, it downloads a ransom note “HOW_TO_RECOVER_ENCRYPTED_FILES.txt” in every folder that contains encrypted files.

DiskDoctor ransomware virus usually spreads via malicious spam emails that contain an infected attachment. If a person opens it, malware is dropped on the system and starts causing system changes. Once it settles in Windows OS, it starts scanning the system looking for the targeted files for the encryption. 

When all files are locked with .DiskDoctor extension, malware drops a ransom note in the text file. This document includes information about data recovery instructions and threatens not to use any other methods to retrieve stolen data: 

Warning all your files is encrypted are !!! 
The receive the decoder's the To, a must you the send an email to  the email address with your personal ID: 
with In response you will of the receive Further instructions. 
The Do not Attempt * to uninstall the program or the run  antivirus software. 
Attempts to the self *-decrypt the files is will of of result in the  loss of your data. 
Decoders of OTHER * the users are Incompatible with your  data, as with the each user has a unique encryption key. 

DiskDoctor ransomware gives each victim a unique identification number which is provided in the ransom note. As you can see from the quote above, developers of the virus require to send it to the contact email address. Crooks are supposed to respond with data decryption solution.

There's no doubt that criminals will ask to pay a specific amount of money in Bitcoins or other cryptocurrencies. The size of the ransom is unknown, but it might differ from victim to victim based on the amount and importance of the encrypted data. The most important part is that payment does not guarantee that you will get a needed decryption software.

Cybersecurity specialists from[2] inform that cyber criminals might disappear as soon as they get the payment. These people are only interested in getting an easy money; data recovery is optional for them. Thus, you should not risk. No one can guarantee that crooks will give you a mercy and release encrypted files. 

We highly recommend focusing on DiskDoctor removal instead of looking for the ways to decrypt data. Currently, the official and safe to use decryptor is not released yet. The only possibility to restore all files is to use backups. However, if you do not have them, there's still a possibility to recover at least some of them. We have provided a couple of alternative methods that might help.

However, before trying data recovery options, you have to remove DiskDoctor from the machine. While it sits inside the computer, it might encrypt your files again and again. This malicious program runs every time when a device is turned on. Hence, begin system scan with Reimage Reimage Cleaner Intego and get rid of the cyber threat in order to try recovery methods and protect new files from the encryption.

Spam emails might contain not so innocent attachments

Various research data tell that ransomware is most likely to strike from malicious email attachments. This distribution method is the most popular one for a couple of years. Unfortunately, it's the most effective too. Crooks learned how to use social engineering and create convincing emails that trick users into opening an obfuscated attachment.

Usually, these letters seem legitimate and contain safe-looking files, for instance, Microsoft Word. However, even such innocent file can contain malicious macros that install malware payload on the system immediately. So, it's important to be careful with received emails. We highly recommend keeping away from spam folder: do not open these letters and keep away from all clickable content inside of it.

In some rare occasions, developers of ransomware use other distribution strategies, such as:

  • displaying malware-laden ads on legitimate and high-risk websites;
  • upload obfuscated programs to file-sharing[3] programs;
  • deliver fake security or update alerts asking to download specific content;
  • launch brute-force attacks.

Hence, following basic cyber security tips is needed to minimize the risk of the attack. Creating backups is also important. If you fail to identify phishing email or install bogus programs and let ransomware inside, you don't need to worry about lost files. They are safely stored in external or cloud drive.

DiskDoctor ransomware elimination guide for Windows users

To remove DiskDoctor correctly we advise you to use professional anti-malware tools, for instance, Reimage Reimage Cleaner Intego, SpyHunter 5Combo Cleaner, Malwarebytes.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove DiskDoctor from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by security experts.

If your files are encrypted by DiskDoctor, you can use several methods to restore them:

Data Recovery Pro – professional tool for restoring compromised files

This tool is designed to recover encrypted or accidentally deleted files on your computer. It's not an official decryptor for ransomware, so it may not restore all of the data.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by DiskDoctor ransomware;
  • Restore them.

Windows Previous Versions feature – for individual file recovery

This feature works for restoring files, but only when System Restore was enabled before ransomware infiltration.

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

ShadowExplorer can help restore lost files if DiskDoctor ransomware left Shadow Copies

If you were successful and virus left those Shadow Copies you can follow these steps and use ShadowExplorer

  • Download Shadow Explorer (;
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

DiskDoctor decryptor is not available yet

We want to discourage you from obtaining decryptor provided by cyber criminals. If none of the above-mentioned methods helped to restore files, please be patient. Hopefully, IT specialists and malware researchers will crack ransomware's code and create a free decryptor soon.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from DiskDoctor and other ransomwares, use a reputable anti-spyware, such as Reimage Reimage Cleaner Intego, SpyHunter 5Combo Cleaner or Malwarebytes

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. It is a hassle when your website is protected from suspicious connections and unauthorized IP addresses.

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 server or network manager that need to monitor connections and activities. This is how you bypass some of the authentications factors and can remotely use your banking accounts without triggering suspicious with each login. 

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. It is better to clock the access to your website from different IP addresses. So you can keep the project safe and secure when you have the dedicated IP address VPN and protected access to the content management system.

Backup files for the later use, in case of the malware attack

Computer users can suffer various losses due to cyber infections or their own faulty doings. Software issues created by malware or direct data loss due to encryption can lead to problems with your device or permanent damage. When you have proper up-to-date backups, you can easily recover after such an incident and get back to work.

It is crucial to create updates to your backups after any changes on the device, so you can get back to the point you were working on when malware changes anything or issues with the device causes data or performance corruption. Rely on such behavior and make file backup your daily or weekly habit.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware occurs out of nowhere. Use Data Recovery Pro for the system restoring purpose.
