DoppelPaymer ransomware removal instructions

What is DoppelPaymer?

DoppelPaymer is a ransomware-type malware that is designed to prevent victims from accessing their files by encrypting them. To be able to use their files again victims are forced to pay cyber criminals a ransom. Research shows that cyber criminals use DoppelPaymer in targeted attacks. It means that they target specific companies and/or industries. Quite often cyber criminals who have a specific target seek to infiltrate (infect) a whole network, i.e., computers used in a particular company. This ransomware appends the ".locked" extension to a filename of every encrypted file, for example, it changes "1.jpg" to "1.jpg.locked", and so on. Every encrypted file gets its own ransom note (.txt file). For instance, a note for "1.jpg.locked" is "1.jpg.readme2unlock.txt", and so forth.

All ransom notes contain identical text. As stated in them, victims should not shut down or restart their computers, rename or delete encrypted files (and ransom notes), or try to restore files using any software. According to cyber criminals, such actions might lead to permanent data loss. In order to get instructions on how to decrypt data, victims have to install Tor browser and open the link which is provided in every created ransom note. It is mentioned that victims have 7 days to use the link, after that it will become invalid. Also, it is stated that the faster victims will contact DoppelPaymer's developers, the lower the price of a decryption will be. The aforementioned link opens a Tor website where victims can contact cyber criminals via an online chat. A screenshot of a Tor website that was generated when cyber criminals targeted the Ohio Gratings Inc. company is provided below. Typically, malware like DoppelPaymer ransomware encrypts files with strong algorithms and it is impossible for victims to decrypt data without tools that only developers of a particular ransomware have. Unfortunately, even if cyber criminals have those tools, they tend not to send them. Simply said, quite often victims who pay a ransom get scammed. In most cases the only (and free) way to recover files without using tools that can be purchased only from cyber criminals is to restore them from a backup it was not encrypted too. Besides, encrypted files remain encrypted even if victims uninstall ransomware from the system. Uninstalling such malware only prevents it from causing further encryptions.

DoppelPaymer decrypt instructions

More examples of ransomware-type software are Nvram, Major and Lokf. In most cases it is designed to encrypt data and create or display a ransom note with instructions on how to pay for a decryption tool and/or key. Two main (and most common) differences are size of a ransom and cryptographic algorithm (symmetric or asymmetric) that ransomware uses to encrypt data. Unluckily, most of these programs cause strong encryptions and it is impossible to decrypt files without tools that only developers of a particular ransomware can provide. It is possible to recover files without their help only if a program contains bugs, flaws, etc. That is why it is important to have a backup of data created and keep it on a remote server or unplugged storage device.

How did ransomware infect my computer?

Most cyber criminals spread malicious programs (including ransomware) through spam campaigns, Trojans, fake software updaters, untrustworthy software download channels/tools and unofficial software 'cracking' (activation) tools. Very often cyber criminals send emails with files attached to them that, if opened, install malicious software. Examples of files that they usually attach are Microsoft Office and PDF documents, archive files like ZIP, RAR, executable files (.exe and others) and JavaScript files. It is worth mentioning that they disguise such emails as important, official, and so on. Trojans infect systems by installing additional malware. These are malicious programs that usually are designed to cause chain infections. Nevertheless, they cause damage only if they are already installed. Fake software updaters are tools that install malware instead of fixes, updates, or exploit bugs, flaws of outdated software that is installed on the operating system. Untrustworthy software download channels/sources are being used as tools to spread malware too. Some examples of unreliable download channels are free file hosting and freeware download websites, Peer-to-Peer networks (like torrent clients, eMule, etc.), unofficial websites and third party downloaders. They often include malicious files that are disguised as legitimate, harmless. By downloading and opening those files people install malicious software by themselves. Unofficial activation tools supposed to bypass paid activations of licensed software. However, quite often these tools are designed by cyber criminals who use them with a purpose to spread malicious programs. Simply said, if used, these tools can cause installation of various high-risk malware.

How to protect yourself from ransomware infections?

We strongly recommend not to open attachments and/or web that are included in irrelevant emails, especially if they are sent from suspicious, unknown addresses. Also, software should not be downloaded using some third party downloaders, unofficial pages and other sources that were mentioned in the paragraph above. The safest way to download it is to use official websites and direct download links for that. Also, installed software should always be up do date, however, it should be updated properly: using tools and/or functions that are provided (designed) by official software developers. Third party tools should never be used. The same applies to software activation ('cracking') tools, besides, it is not legal to use them. And finally, we advise to regularly scan operating system with a reputable antivirus or anti-spyware software and keep it up to date. If your computer is already infected with DoppelPaymer, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

4. In the opened window, click "Next".

restore system files and settings

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 DoppelPaymer ransomware virus infiltrating your PC).

select a restore point

6. In the opened window, click "Yes".

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining DoppelPaymer 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 DoppelPaymer 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.

Restoring files encrypted by CryptoDefense

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 regain control of the files encrypted by DoppelPaymer, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.

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 DoppelPaymer 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, and Desktop folders.

Controll Folder Access

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:
