DoppelPaymer ransomware removal instructions

What is DoppelPaymer?

DoppelPaymer is ransomware-type malware designed to prevent victims from accessing their files by encryption. To regain access, victims are encouraged to pay cyber criminals a ransom. Research shows that criminals use DoppelPaymer in targeted attacks. I.e., they target specific companies and/or industries. Criminals who have a specific target often seek to infiltrate (infect) the whole network (for example, all computers used within a particular company). This ransomware appends the ".locked" extension to the filename of each encrypted file. For example, "1.jpg" becomes "1.jpg.locked". Each encrypted file receives an associated ransom message within a .txt file. For instance, the message for "1.jpg.locked" is contained within "1.jpg.readme2unlock.txt", and so on. Updated variants of this ransomware use ".doppeled" extension for encrypted files.

All ransom messages contain identical text stating that victims should not shut down or restart their computers, rename/delete encrypted files or ransom messages, or try to restore files using other software. According to cyber criminals, these actions might lead to permanent data loss. To get instructions about how to decrypt data, victims must install the Tor browser and open a link, which is provided in each created ransom message. It is mentioned that victims have seven days to use the link, after which it becomes invalid. Furthermore, it is stated that the faster victims contact DoppelPaymer's developers, the lower the cost of decryption. The aforementioned link opens a Tor website on which victims can contact cyber criminals via online chat. A screenshot of the Tor website, which was generated when cyber criminals targeted the Ohio Gratings Inc. company, is provided below. Typically, malware such as DoppelPaymer ransomware encrypts files with strong algorithms, and thus it is impossible for victims to decrypt data without specific tools held only by the developers of the ransomware. Unfortunately, even if cyber criminals have these tools, they tend not to send them - victims who pay are generally scammed. In most cases, the only free way to recover files without using tools purchased from cyber criminals is to restore them from a backup (provided is was not also encrypted). Files remain encrypted even if victims uninstall ransomware from the system. Uninstalling this malware simply prevents further encryption.

More examples of ransomware-type software include Nvram, Major, and Lokf. In most cases, it is designed to encrypt data and create or display a ransom message with instructions about how to pay for a decryption tool and/or key. Common differences are size of ransom and cryptographic algorithm (symmetric or asymmetric) that ransomware uses to encrypt data. Most of these programs use strong encryption and thus it is impossible to decrypt files without tools held only by the developers of the ransomware, unless the program has bugs, flaws, etc. Therefore, maintain a backup of data and keep it on a remote server or unplugged storage device.

How did ransomware infect my computer?

Most cyber criminals proliferate malicious programs (including ransomware) through spam campaigns, Trojans, fake software updaters, untrustworthy software download channels/tools and unofficial software 'cracking' (activation) tools. Cyber criminals send emails with files attached. If opened, these install malicious software. Examples of files they usually attach are Microsoft Office and PDF documents, archive files such as ZIP, RAR, executable files (.exe and others), and JavaScript files. They disguise the emails as important, official, and so on. Trojans infect systems by installing additional malware. These are malicious programs that often cause chain infections, however, they they are only effective if already installed. Fake software updaters are tools that install malware rather than fixes/updates, or they exploit bugs/flaws of outdated software installed on the operating system. Untrustworthy software download channels/sources are used to proliferate malware. Some examples of dubious download channels are free file hosting and freeware download websites, Peer-to-Peer networks (torrent clients, eMule, etc.), unofficial websites, and third party downloaders. They often include malicious files that are disguised as legitimate and harmless. By downloading and opening these files, people often install malicious software. Unofficial activation tools supposedly bypass paid activation of licensed software, however, they are commonly designed by cyber criminals to spread malicious programs - they can cause installation of various high-risk malware.

How to protect yourself from ransomware infections

Do not open attachments or web links included in irrelevant emails, especially if they are sent from suspicious, unknown addresses. Do not download software using third party downloaders, unofficial web pages, or the other sources mentioned above. The safest way to download is using official websites and direct download links. Keep installed software up to date, however, it should be updated properly using tools and/or functions provided by the official software developers. Third party tools should never be used. The same applies to software activation ('cracking') tools. Note that it is illegal to use these tools. Finally, regularly scan the operating system with 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 Malwarebytes for Windows to automatically eliminate this ransomware.

Malicious DoppelPaymer process running in Task Manager as "SpotLife WebAlbum Service Plugin":

Update February 4, 2020 - Crooks have released an updated version of DoppelPaymer ransomware which is virtually the same. The main difference is threats that are written on its website. Originally, developers claimed that they've stolen some data and will make it public unless the ransom is paid. However, the current version claims that the data will be either made public or sold in the dark web to other cyber criminals. Which one is worse depends on who gets their hands on the data. If your information is public, but no one is there to search for or abuse it, then the harm may not be done. However, cyber criminals who buy personal information do this with an intention of gaining value - stealing credit cards, identities, etc. Therefore, users who have their personal data stolen may face a lot of issues.

Update February 27, 2020 - The developers of DoppelPaymer ransomware have recently started leaking information stolen from various victims. The data is stored in a public website named "Dopple Leaks" hosted in the Tor network:

Update June 10, 2020 - The developers of DoppelPaymer ransomware have recently breached a network belonging to one of NASA's contractors' - a company named Digital Management Inc. Once infiltrated, crooks stole thousands of files containing classified information, such as HR documents, project details, information about employees, and so forth. As a proof, ransomware developers have leaked a small portion of stolen files in the dark web. There's no doubt that the rest will be used for extortion purposes.

Isolating the infected device:

Some ransomware-type infections are designed to encrypt files within external storage devices, infect them, and even spread throughout the entire local network. For this reason, it is very important to isolate the infected device (computer) as soon as possible.

Step 1: Disconnect from the internet.

The easiest way to disconnect a computer from the internet is to unplug the Ethernet cable from the motherboard, however, some devices are connected via a wireless network and for some users (especially those who are not particularly tech-savvy), disconnecting cables may seem troublesome. Therefore, you can also disconnect the system manually via Control Panel:

Navigate to the "Control Panel", click the search bar in the upper-right corner of the screen, enter "Network and Sharing Center" and select search result:

Click the "Change adapter settings" option in the upper-left corner of the window:

Right-click on each connection point and select "Disable". Once disabled, the system will no longer be connected to the internet. To re-enable the connection points, simply right-click again and select "Enable".

Step 2: Unplug all storage devices.

As mentioned above, ransomware might encrypt data and infiltrate all storage devices that are connected to the computer. For this reason, all external storage devices (flash drives, portable hard drives, etc.) should be disconnected immediately, however, we strongly advise you to eject each device before disconnecting to prevent data corruption:

Navigate to "My Computer", right-click on each connected device and select "Eject":

Step 3: Log-out of cloud storage accounts.

Some ransomware-type might be able to hijack software that handles data stored within "the Cloud". Therefore, the data could be corrupted/encrypted. For this reason, you should log-out of all cloud storage accounts within browsers and other related software. You should also consider temporarily uninstalling the cloud-management software until the infection is completely removed.

Identify the ransomware infection:

To properly handle an infection, one must first identify it. Some ransomware infections use ransom-demand messages as an introduction (see the WALDO ransomware text file below).

This, however, is rare. In most cases, ransomware infections deliver more direct messages simply stating that data is encrypted and that victims must pay some sort of ransom. Note that ransomware-type infections typically generate messages with different file names (for example, "_readme.txt", "READ-ME.txt", "DECRYPTION_INSTRUCTIONS.txt", "DECRYPT_FILES.html", etc.). Therefore, using the name of a ransom message may seem like a good way to identify the infection. The problem is that most of these names are generic and some infections use the same names, even though the delivered messages are different and the infections themselves are unrelated. Therefore, using the message filename alone can be ineffective and even lead to permanent data loss (for example, by attempting to decrypt data using tools designed for different ransomware infections, users are likely to end up permanently damaging files and decryption will no longer be possible even with the correct tool).

Another way to identify a ransomware infection is to check the file extension, which is appended to each encrypted file. Ransomware infections are often named by the extensions they append (see files encrypted by Qewe ransomware below).

This method is only effective, however, when the appended extension is unique - many ransomware infections append a generic extension (for example, ".encrypted", ".enc", ".crypted", ".locked", etc.). In these cases, identifying ransomware by its appended extension becomes impossible.

One of the easiest and quickest ways to identify a ransomware infection is to use the ID Ransomware website. This service supports most existing ransomware infections. Victims simply upload a ransom message and/or one encrypted file (we advise you to upload both if possible).

The ransomware will be identified within seconds and you will be provided with various details, such as the name of the malware family to which the infection belongs, whether it is decryptable, and so on.

Example 1 (Qewe [Stop/Djvu] ransomware):

Example 2 (.iso [Phobos] ransomware):

If your data happens to be encrypted by a ransomware that is not supported by ID Ransomware, you can always try searching the internet by using certain keywords (for example, ransom message title, file extension, provided contact emails, cryptowallet addresses, etc.).

Encryption algorithms used by most ransomware-type infections are extremely sophisticated and, if the encryption is performed properly, only the developer is capable of restoring data. This is because decryption requires a specific key, which is generated during the encryption. Restoring data without the key is impossible. In most cases, cyber criminals store keys on a remote server, rather than using the infected machine as a host. Dharma (CrySis), Phobos, and other families of high-end ransomware infections are virtually flawless, and thus restoring data encrypted without the developers' involvement is simply impossible. Despite this, there are dozens of ransomware-type infections that are poorly developed and contain a number of flaws (for example, the use of identical encryption/decryption keys for each victim, keys stored locally, etc.). Therefore, always check for available decryption tools for any ransomware that infiltrates your computer.

Finding the correct decryption tool on the internet can be very frustrating. For this reason, we recommend that you use the No More Ransom Project and this is where identifying the ransomware infection is useful. The No More Ransom Project website contains a "Decryption Tools" section with a search bar. Enter the name of the identified ransomware, and all available decryptors (if there are any) will be listed.

Depending on the situation (quality of ransomware infection, type of encryption algorithm used, etc.), restoring data with certain third-party tools might be possible. Therefore, we advise you to use EaseUS Data Recovery Wizard Pro. This tool supports over a thousand data types (graphics, video, audio, documents, etc.) and it is very intuitive (little knowledge is necessary to recover data).

EaseUS Data Recovery Wizard Pro

By downloading any software listed on this website you agree to our Privacy Policy and Terms of Use. Trial version of EaseUS Data Recovery Wizard Pro is capable of scanning drives and listing recoverable files - to restore them, you must purchase a license.

Step 1: Perform a scan.

Hover your mouse over the partition you wish to scan and select "Scan". You can also select a specific folder, or click shortcut icons to scan the Desktop or Recycle Bin:

Wait for EaseUS Data Recovery Wizard Pro to complete the scan. The scanning duration depends on the volume of files (both in quantity and size) that you are scanning (for example, several hundreds gigabytes could take over an hour to scan). Therefore, be patient during the scanning process. We also advise against modifying or deleting existing files, since this might interfere with the scan. If you add additional data (for example, downloading files/content) while scanning, this will prolong the process:

Step 2: Recover data.

Once the process is complete, select the folders/files you wish to restore and simply click "Recover". Note that some free space on your storage drive is necessary to restore data. Note also that the trial version of EaseUS Data Recovery Wizard Pro is only capable of scanning drives and listing recoverable files - to restore them, you must purchase a license:

Step 3: Save the scan session (optional).

We recommend that you save the scanning session once you have completed recovery, in case you decide to recover additional files later. Simply click the "Save Scan Session" icon in the upper-right corner of the screen and choose the location for the file to be saved. This will save a lot of time, since you will not need to re-scan the storage drive the next time you wish to restore something. Bear in mind, however, that data removed after the scanning session has finished will not be listed:

Create data backups:

Proper file management and creating backups is essential for data security. Therefore, always be very careful and think ahead.

Partition management: We recommend that you store your data in multiple partitions and avoid storing important files within the partition that contains the entire operating system. If you fall into a situation whereby you cannot boot the system and are forced to format the disk on which the operating system is installed (in most cases, this is where malware infections hide), you will lose all data stored within that drive. This is the advantage of having multiple partitions: if you have the entire storage device assigned to a single partition, you will be forced to delete everything, however, creating multiple partitions and allocating the data properly allows you to prevent such problems. You can easily format a single partition without affecting the others - therefore, one will be cleaned and the others will remain untouched, and your data will be saved. Managing partitions is quite simple and you can find all necessary information on Microsoft's documentation web page.

Data backups: The most reliable backup method is to use an external storage device and keep it unplugged. Copy your data to an external hard drive, flash (thumb) drive, SSD, HDD, or any other storage device, unplug it and store it in a dry place away from sun and extreme temperatures. This method is, however, quite inefficient, since data backups and updates need to be made regularly. You can also use a cloud service or remote server. Here, an internet connection is required and there is always the chance of a security breach. Therefore, you should consider using an application to create data backups locally.

EaseUS Todo Backup

By downloading any software listed on this website you agree to our Privacy Policy and Terms of Use. To use full-featured product, you have to purchase a license for EaseUS Todo Backup. 30 days free trial available.

We recommend using the EaseUS Todo Backup application. The "Home" edition of EaseUS Todo Backup is usually more than adequate for regular users, however, the "Business" edition is more suitable for companies and large computer networks. The EaseUS Todo Backup application provides extensive data protection features. You can easily create backups, and encrypt and compress them for enhanced protection and storage saving purposes. It also allows you to set backup schedules, create bootable devices, and restore the system if a crash occurs. You can easily choose where to store the created backup: locally; uploaded to an external drive; FTP; cloud storage, or elsewhere. In summary, EaseUS Todo Backup is an all-in-one tool, which provides all features required to properly backup your data.

Creating a data backup:

The backup process is virtually identical regardless of the item (file, partition, entire system) you wish to backup. Taking the File Backup feature as an example:

Step 1: Choose which item to backup.

Click on the "Menu" icon in the upper-left corner of the screen to reveal the menu and select "File Backup":

Select the files you want to backup. You can also enter a name and description of the backup that will be created:

Step 2: Change the default settings.

The EaseUS Todo Backup application provides a variety of additional options that can be added/modified while creating the backup. For example, you can encrypt data (add a password), select the compression rate (how much the backup should be compressed), performance (how many system resources should be allocated), add an email notification (you receive an email once the process is complete) and so on.

To open the options window, click the "Backup options" button in the lower-left corner of the screen:

Select the settings you want to change and click "Save". You can also reset your changes by clicking "Reset to initial settings":

Step 3: Select the backup destination.

As mentioned above, EaseUS Todo Backup allows you to choose where backups are saved - locally or externally.

Click the "Browse..." button and select the location you want the backup to be saved:

Step 4: Safety measures and process completion.

Depending on the location you have chosen, there are a number of measures you should or should not take. If you are uploading to an internet-connected location (for example, Cloud storage, FTP, etc.), be sure to maintain your internet connection, otherwise you will have to start again. The same applies to external storage devices - do not unplug them until the process is complete.

The progress bar displays estimated time remaining until completion. Large backups (hundreds of gigabytes) can take hours to create (depending on storage device speed, internet connection, etc.). Therefore, the application also allows you to optionally choose what the system should do (shut down, sleep or hibernate) once the process has finished:

The best way to avoid damage from ransomware infections is to maintain regular up-to-date backups.
