Jope ransomware removal instructions

What is Jope?

There are many ransomware-type programs that belong to the Djvu family, Jope is one of them. It encrypts victim's files, adds a new extension to their filenames and creates a ransom note. Jope renames encrypted files by appending the ".jope" extension to their filenames, for example, it renames "1.jpg" to "1.jpg.jope", "2.jpg" to "2.jpg.jope", etc. Instructions on how to contact cyber criminals, details like size of a ransom and other information are provided in a text file named "_readme.txt". Credits for discovering Jope ransomware belong to Michael Gillespie.

As stated in the ransom note, Jope encrypts files (documents, photos, databases, etc.) by using a strong encryption. Files can be encrypted with a decryption software and unique key that cost $980 or $490, their price depends on how fast victims are going to contact Jope's developers. In order to be able to purchase decryption software and key for $490 victims have to contact cyber criminals in the first 72 hours after encryption. It can be done by writing an email to or, it has to contain the assigned personal ID. When contacted, Jope's developers should provide a cryptocurrency wallet address that has to be used to pay a ransom. In most cases cyber criminals behind a particular ransomware are the only ones who can help victims to decrypt their files. What is worse, victims who trust them (pay a ransom) tend to get scammed - cyber criminals do not send them a decryption tool and/or key even after a payment. Typically, the only way to recover files without having to purchase any decryption tools and risking to get scammed is to restore them from a backup. It is worthwhile to mention that victims who uninstall ransomware prevent it from causing further encryptions. Although, encrypted files remain inaccessible.

More examples of software of this type are Mado, N2019cov and UPPER. In most cases ransomware is designed to encrypt files and provide (create and/or display) some ransom note. Usually main and most common variables are encryption algorithm (symmetric or asymmetric) that ransomware uses to encrypt data size of a ransom. Either way, most of the times it is impossible to decrypt files without tools that only cyber criminals who designed a particular ransomware have. It is possible only in cases where ransomware is not finished (has bugs, flaws, etc.). Unfortunately, it happens rarely and victims can recover their files without losing money only by using a data backup. Therefore, it is important to always have data backed up and keep it stored on a remote server and/or unplugged storage device.

How did ransomware infect my computer?

One of the most popular ways to spread malicious programs is by using spam campaigns. Cyber criminals send malicious files or website links designed to download them via email. Their main goal is to trick recipients into executing malicious file. Typically, they attach Microsoft Office documents, PDF documents, executables like .exe, archive files (like ZIP, RAR or JavaScript files. Another way to infect systems with ransomware or other malware is by tricking users installing some Trojan. Malicious programs of this type often are designed to cause chain infections - they install other malicious software. Fake software updating tools can cause ca infect systems by installing malware instead updating installed software, or by exploiting bugs, flaws of outdated programs. Untrustworthy software download sources such as freeware download websites, free file hosting websites, Peer-to-Peer networks (like torrents, eMule etc), various third party downloaders can be used as tools to distribute malware too. It is common that cyber criminals use them as tools to upload, host malicious files. It means that files that are downloaded through such sources, if opened, might lead to installation of malware like ransomware. One more way to proliferate malware is through software 'cracking' (unofficial activation) tools. These programs supposed to activate licensed software for free. Nevertheless, they can be and often are designed to install malware instead.

How to protect yourself from ransomware infections?

Programs should be downloaded only from official websites and through direct links. Other channels like third party downloaders, Peer-to-Peer networks, unofficial websites, etc., can be used by cyber criminals to spread malicious software. The same applies to various third party installers. Operating system and installed programs must be updated by using implemented functions and/or tools that are designed by the official software developers. Unofficial activation ('cracking') and updating tools can be designed to install malware. Besides, it is not legal to activate licensed software with programs of this type (third party activators). Attachments and/or links in irrelevant emails that are received from suspicious, unknown addresses should not be opened. It is common that such emails are being sent by cyber criminals who attempt spread malware. It is worth mentioning that they often disguise their emails as important, official, and so on. And finally, operating system is safer if it is regularly scanned with a reputable antivirus or anti-spyware software. Therefore, we recommend to have one installed and always keep it up-to-date. If your computer is already infected with Jope, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this ransomware.

IMPORTANT NOTE! - As well as encrypting data, ransomware-type infections from the Djvu malware family also add a number of entries to the Windows "hosts" file. The entries contain URLs of various websites, most of which are related to malware removal. This is done to prevent users from accessing malware security websites and seeking help. Our website ( is also on the list. Removing these entries, however, is simple - you can find detailed instructions in this article (note that, although the steps are shown in the Windows 10 environment, the process is virtually identical on all versions of the Microsoft Windows operating system).

There are currently two versions of Djvu ransomware infections: old and new. The old versions were designed to encrypt data by using a hard-coded "offline key" whenever the infected machine had no internet connection or the server was timing out/not responding. Therefore, some victims were able to decrypt data using a tool developed by cyber security researcher, Michael Gillespie, however, since the encryption mechanism has been slightly changed (hence the new version, released in August, 2019), the decrypter no longer works and it is not supported anymore. If your data has been encrypted by an older version, you might be able to restore it with the another tool developed by Emsisoft and Michael Gillespie. It supports a total of 148 Djvu's variants and you can find more information, as well as download link and decryption instructions in Emsisoft's official page.

Additionally, Emsisoft is now providing a service that allows to decrypt data (again, only if it was encrypted by Djvu variants released before August, 2019) for those victims who have a pair of the same file before and after the encryption. All victims have to do is upload a pair of original and encrypted file to Emsisoft's Djvu decryption page and download the aforementioned decryption tool (the download link will be provided after uploading files). Note that the file processing may take some time so be patient. It is also worth mentioning that the system must have an Internet connection during the entire decryption process, otherwise it will fail.

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