Devil ransomware removal instructions

What is Devil?

Devil is a part of Dharma, a family of ransomware-type programs. It renames encrypted files by appending victim's ID, developer's email address and ".devil" extension to their filenames. For example, it renames a file named "1.jpg" to "1.jpg.id[1E857D00-2574].[decrypt4data@protonmail.com].devil", and so on. Like most programs of this type, Devil provides victims with instructions on how to contact its developers/decrypt files as well. In this case it creates the "info.txt" file and displays a pop-up window (info.hta). Updated variants of this ransomware use ".[theblackarrow@tuta.io].devil" extension for encrypted files.

As stated in the pop-up window, Devil encrypts all files and they cannot be decrypted without a decryption tool and/or key that can be purchased from its developers. Instructions on how to purchase it can be received by writing an email to decrypt4data@protonmail.com, it is mentioned that price of a decryption depends on how fast victims will contact these cyber criminals. Devil's developers promise to send a decryption tool after a payment. Also, they offer a free decryption of 5 files that can be sent to them via the provided email address. However, those files should not be larger than 4MB and contain valuable information. It is also stated that by renaming or trying to decrypt files with some other software victims may cause permanent data loss and/or increase price of a decryption. Unfortunately, there are no other (and free) tools that could decrypt files encrypted by Devil, at least not at the moment. However, we do not recommend to trust these or any other cyber criminals (ransomware developers), quite often they do not send decryption tools and/or keys even if victims meed all their demands (pay them a ransom). It means that they only way to recover files without having to pay a ransom (and risking to be scammed) is to restore them from a backup. It is worth mentioning that files remain encrypted even if ransomware is uninstalled/removed from the operating system. However, it is worth doing because removal of ransomware prevents it from causing further data loss (encryptions).

More examples of malicious programs that are classified as ransomware are NEMTY 2.5 REVENGE, Helpforyoupc and Zeoticus. What most of them have in common is that they are designed to prevent victims from accessing their files and create ransom notes. Typically, two main differences are cryptographic algorithm (symmetric or asymmetric) that ransomware uses to encrypt data and size of a ransom that its developers demand to be paid. Most of the times cyber criminals behind a particular ransomware are the only ones who can help victims to decrypt files/have tools that can decrypt encrypted data. It is possible to avoid data (and financial) loss only when ransomware contains bugs, flaws or other vulnerabilities, and/or when victims have a data backup. That is why it is always a good idea to have a backup of data created and keep it on some remote server or unplugged storage device.

How did ransomware infect my computer?

Quite often cyber criminals attempt to trick people into installing various malware by sending emails that are disguised as important, official and contain malicious attachments and/or web links that are designed to download malicious files. If opened, those files/attachments infect operating systems with malware. Some examples of files that are being attached to such emails are Microsoft Office, PDF documents, JavaScript files, executable files like .exe, and archives in ZIP, RAR and other formats. Another way to unintentionally install malicious software is to open a file downloaded through an untrustworthy source. For example, unofficial website, free file hosting or freeware download website, Peer-to-Peer network like torrent client, eMule, third party downloader, and other source of this kind. Furthermore, malicious software can be distributed through other software of this type called Trojan. Trojan is a type of malicious program that is often designed to cause chain infections/install other malware. However, it can happen only if a Trojan is already installed on the operating system. Quite often various unofficial software activation and updating tools lead to installation of malicious software too. They install malware instead of activating or updating software. Additionally, fake/unofficial updating tools can infect systems by exploiting bugs, flaws of outdated software that is installed on the operating system.

How to protect yourself from ransomware infections?

If a received email is irrelevant, it is sent from unknown address and contains some attachment (or website link) it should be ignored. We strongly recommend not to open files (or web links) that are presented in emails of this kind without being sure that it is safe to do that. Software should be downloaded from official websites and direct download links. Other sources (like Peer-to-Peer networks, third party downloaders, unofficial pages, etc.) could be used to proliferate malware. Installed programs should be updated through implemented functions or tools that are provided by official software developers. The same applies to their activation. It is illegal to use third party tools to activate licensed programs and it may lead to having a system infected with malware. And finally, it is important to regularly scan the operating system for threats with a reputable antivirus or anti-spyware suite and always keep it up to date. If your computer is already infected with Devil, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

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 Devil 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 Devil 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 Devil, 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 Devil 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.
