DDE ransomware – a dangerous virus that adds .encrypted extension to locked files

DDE ransomware

DDE ransomware is a newly discovered cryptovirus that enters machines via macro-enabled malicious MS office documents. Researchers believe that the virus comes from Crypt888 ransomware family. DDE virus locks up all personal files using AES encryption algorithm and then appends the .encrypted extension. As soon as malware's payload is distributed, it runs a main executable dde_ransomware.exe. Additionally, the wallpaper is removed and replaced with a red one which contains a ransom note. Victims are urged to contact cybercrooks via and pay ransom for data release. Hackers also add a twist by stating that decryption is also possible without the personal key.

Main executable dde_ransomware.exe

Detection and elimination Use Reimage Reimage Cleaner Intego or Malwarebytes

DDE ransomware also displays a pop-up window with the name “HACKER” that shows the following text:

Your important files are encrypted.
If you need them, You can find my KEY to decrypt.

The ransom message is quite baffling, as it is not clear what crooks are talking about. The only way to recover encoded files is by using a unique key which is usually kept on a remote server by criminals. Nevertheless, it seems like DDE ransomware was made as a joke, as the email address “” does not exist and has nothing to do with Google.

If you found such message on your screen, you are in bad luck, as it seems like the only reliable way to retrieve access to files is by recovering them from a backup. However, before you proceed with data recovery, you should take care of DDE ransomware removal promptly. We suggest using powerful anti-malware software, such as Reimage Reimage Cleaner Intego or Malwarebytes.

DDE ransomware makes a series of changes to the targeted machine. As soon as it enters, it boots an executable file which is run in the background, modifies Windows Registry to retain persistence and downloads malicious apps using Background Intelligent Transfer Service used by Windows. Finally, malware deletes Shadow Volume Copies.

DDE virus then scans the computer and looks for personal files, including:

  • Images
  • Pictures
  • MS Office and OpenOffice documents
  • Video
  • Audio
  • Databases
  • Archives, etc.

As soon as encryption is complete, users lose access to all personal data. The only way to decrypt files is by using backups. Additionally, third-party software may be able to help – please see instructions below.

Security experts recommend you to remove DDE ransomware using reliable anti-malware software. However, you should never attempt to get rid of the virus manually, as you could damage your machine even more.

Ransomware-type viruses are not a new threat and have been around for over ten years. Unfortunately, it seems like it is not a long enough time for users to learn the very basics of internet security and virtual safety.

To avoid ransomware infection, please follow these simple tips:

  • Install anti-malware software and keep it up to date;
  • Always patch the operating system as soon as updates are out;
  • Do not open suspicious emails (most of them land in the Spam folder) or its attachments;
  • Backup all your files and keep it on a remote device such as a USB stick or a cloud account (OneDrive, iCloud, Dropbox, etc.);
  • Do not download cracked software;
  • Set all your software to update itself automatically – it is less likely to click on fake update pop-up;
  • Scan every executable using security software before opening it;
  • Avoid websites of questionable content, such as porn, file-sharing, gambling and other sites.

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

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

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
